    Description: The final identity and functional properties of a neuron are specified by terminal differentiation genes, which are controlled by specific motifs in compact regulatory regions. To determine how these sequences integrate inputs from transcription factors that specify cell types, we compared the regulatory mechanism of Drosophila Rhodopsin genes that are expressed in subsets of photoreceptors to that of phototransduction genes that are expressed broadly, in all photoreceptors. Both sets of genes share an 11-base pair (bp) activator motif. Broadly expressed genes contain a palindromic version that mediates expression in all photoreceptors. In contrast, each Rhodopsin exhibits characteristic single-bp substitutions that break the symmetry of the palindrome and generate activator or repressor motifs critical for restricting expression to photoreceptor subsets. Sensory neuron subtypes can therefore evolve through single-bp changes in short regulatory motifs, allowing the discrimination of a wide spectrum of stimuli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rister, Jens -- Razzaq, Ansa -- Boodram, Pamela -- Desai, Nisha -- Tsanis, Cleopatra -- Chen, Hongtao -- Jukam, David -- Desplan, Claude -- K99EY023995/EY/NEI NIH HHS/ -- R01 EY13010/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1258-61. doi: 10.1126/science.aab3417.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Developmental Genetics, Department of Biology, New York University, 100 Washington Square East, New York, NY 10003-6688, USA. ; Center for Developmental Genetics, Department of Biology, New York University, 100 Washington Square East, New York, NY 10003-6688, USA. cd38@nyu.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26785491" target="_blank"〉PubMed〈/a〉

    Description: Congenital heart disease (CHD) patients have an increased prevalence of extracardiac congenital anomalies (CAs) and risk of neurodevelopmental disabilities (NDDs). Exome sequencing of 1213 CHD parent-offspring trios identified an excess of protein-damaging de novo mutations, especially in genes highly expressed in the developing heart and brain. These mutations accounted for 20% of patients with CHD, NDD, and CA but only 2% of patients with isolated CHD. Mutations altered genes involved in morphogenesis, chromatin modification, and transcriptional regulation, including multiple mutations in RBFOX2, a regulator of mRNA splicing. Genes mutated in other cohorts examined for NDD were enriched in CHD cases, particularly those with coexisting NDD. These findings reveal shared genetic contributions to CHD, NDD, and CA and provide opportunities for improved prognostic assessment and early therapeutic intervention in CHD patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homsy, Jason -- Zaidi, Samir -- Shen, Yufeng -- Ware, James S -- Samocha, Kaitlin E -- Karczewski, Konrad J -- DePalma, Steven R -- McKean, David -- Wakimoto, Hiroko -- Gorham, Josh -- Jin, Sheng Chih -- Deanfield, John -- Giardini, Alessandro -- Porter, George A Jr -- Kim, Richard -- Bilguvar, Kaya -- Lopez-Giraldez, Francesc -- Tikhonova, Irina -- Mane, Shrikant -- Romano-Adesman, Angela -- Qi, Hongjian -- Vardarajan, Badri -- Ma, Lijiang -- Daly, Mark -- Roberts, Amy E -- Russell, Mark W -- Mital, Seema -- Newburger, Jane W -- Gaynor, J William -- Breitbart, Roger E -- Iossifov, Ivan -- Ronemus, Michael -- Sanders, Stephan J -- Kaltman, Jonathan R -- Seidman, Jonathan G -- Brueckner, Martina -- Gelb, Bruce D -- Goldmuntz, Elizabeth -- Lifton, Richard P -- Seidman, Christine E -- Chung, Wendy K -- T32 HL007208/HL/NHLBI NIH HHS/ -- Arthritis Research UK/United Kingdom -- British Heart Foundation/United Kingdom -- Department of Health/United Kingdom -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1262-6. doi: 10.1126/science.aac9396.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, MA, USA.

    Description: Research into stem cells and aging aims to understand how stem cells maintain tissue health, what mechanisms ultimately lead to decline in stem cell function with age, and how the regenerative capacity of somatic stem cells can be enhanced to promote healthy aging. Here, we explore the effects of aging on stem cells in different tissues. Recent research has focused on the ways that genetic mutations, epigenetic changes, and the extrinsic environmental milieu influence stem cell functionality over time. We describe each of these three factors, the ways in which they interact, and how these interactions decrease stem cell health over time. We are optimistic that a better understanding of these changes will uncover potential strategies to enhance stem cell function and increase tissue resiliency into old age.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodell, Margaret A -- Rando, Thomas A -- P01 AG036695/AG/NIA NIH HHS/ -- R01 AG047820/AG/NIA NIH HHS/ -- R01 AR062185/AR/NIAMS NIH HHS/ -- R37 AG023806/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1199-204. doi: 10.1126/science.aab3388.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stem Cells and Regenerative Medicine Center, Center for Cell and Gene Therapy, and Department of Pediatrics, Baylor College of Medicine, Houston, TX 77030, USA. goodell@bcm.edu rando@stanford.edu. ; Glenn Center for the Biology of Aging and Department of Neurology and Neurological Sciences, Stanford University School of Medicine, Stanford, CA 94305, USA, and Center for Regenerative Rehabilitation, Veterans Administration Palo Alto Health Care System, Palo Alto, CA 94304, USA. goodell@bcm.edu rando@stanford.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26785478" target="_blank"〉PubMed〈/a〉

    Description: Mono-ubiquitination of Fancd2 is essential for repairing DNA interstrand cross-links (ICLs), but the underlying mechanisms are unclear. The Fan1 nuclease, also required for ICL repair, is recruited to ICLs by ubiquitinated (Ub) Fancd2. This could in principle explain how Ub-Fancd2 promotes ICL repair, but we show that recruitment of Fan1 by Ub-Fancd2 is dispensable for ICL repair. Instead, Fan1 recruitment--and activity--restrains DNA replication fork progression and prevents chromosome abnormalities from occurring when DNA replication forks stall, even in the absence of ICLs. Accordingly, Fan1 nuclease-defective knockin mice are cancer-prone. Moreover, we show that a Fan1 variant in high-risk pancreatic cancers abolishes recruitment by Ub-Fancd2 and causes genetic instability without affecting ICL repair. Therefore, Fan1 recruitment enables processing of stalled forks that is essential for genome stability and health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770513/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770513/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lachaud, Christophe -- Moreno, Alberto -- Marchesi, Francesco -- Toth, Rachel -- Blow, J Julian -- Rouse, John -- WT096598MA/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):846-9. doi: 10.1126/science.aad5634.

    Description: Hundreds of pathways for degradation converge at ubiquitin recognition by a proteasome. Here, we found that the five known proteasomal ubiquitin receptors in yeast are collectively nonessential for ubiquitin recognition and identified a sixth receptor, Rpn1. A site ( T1: ) in the Rpn1 toroid recognized ubiquitin and ubiquitin-like ( UBL: ) domains of substrate shuttling factors. T1 structures with monoubiquitin or lysine 48 diubiquitin show three neighboring outer helices engaging two ubiquitins. T1 contributes a distinct substrate-binding pathway with preference for lysine 48-linked chains. Proximal to T1 within the Rpn1 toroid is a second UBL-binding site ( T2: ) that assists in ubiquitin chain disassembly, by binding the UBL of deubiquitinating enzyme Ubp6. Thus, a two-site recognition domain intrinsic to the proteasome uses distinct ubiquitin-fold ligands to assemble substrates, shuttling factors, and a deubiquitinating enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shi, Yuan -- Chen, Xiang -- Elsasser, Suzanne -- Stocks, Bradley B -- Tian, Geng -- Lee, Byung-Hoon -- Shi, Yanhong -- Zhang, Naixia -- de Poot, Stefanie A H -- Tuebing, Fabian -- Sun, Shuangwu -- Vannoy, Jacob -- Tarasov, Sergey G -- Engen, John R -- Finley, Daniel -- Walters, Kylie J -- New York, N.Y. -- Science. 2016 Feb 19;351(6275). pii: aad9421. doi: 10.1126/science.aad9421.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA. ; Protein Processing Section, Structural Biophysics Laboratory, Center for Cancer Research, National Cancer Institute, Frederick, MD 21702, USA. ; Department of Chemistry and Chemical Biology, Northeastern University, Boston, MA 02115, USA. ; Protein Processing Section, Structural Biophysics Laboratory, Center for Cancer Research, National Cancer Institute, Frederick, MD 21702, USA.

    Description: The recent rapid spread of Zika virus and its unexpected linkage to birth defects and an autoimmune neurological syndrome have generated worldwide concern. Zika virus is a flavivirus like the dengue, yellow fever, and West Nile viruses. We present the 3.8 angstrom resolution structure of mature Zika virus, determined by cryo-electron microscopy (cryo-EM). The structure of Zika virus is similar to other known flavivirus structures, except for the ~10 amino acids that surround the Asn(154) glycosylation site in each of the 180 envelope glycoproteins that make up the icosahedral shell. The carbohydrate moiety associated with this residue, which is recognizable in the cryo-EM electron density, may function as an attachment site of the virus to host cells. This region varies not only among Zika virus strains but also in other flaviviruses, which suggests that differences in this region may influence virus transmission and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4845755/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4845755/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sirohi, Devika -- Chen, Zhenguo -- Sun, Lei -- Klose, Thomas -- Pierson, Theodore C -- Rossmann, Michael G -- Kuhn, Richard J -- R01 AI073755/AI/NIAID NIH HHS/ -- R01 AI076331/AI/NIAID NIH HHS/ -- R01AI073755/AI/NIAID NIH HHS/ -- R01AI076331/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):467-70. doi: 10.1126/science.aaf5316.

    Description: The nuclear pore complex (NPC) controls the transport of macromolecules between the nucleus and cytoplasm, but its molecular architecture has thus far remained poorly defined. We biochemically reconstituted NPC core protomers and elucidated the underlying protein-protein interaction network. Flexible linker sequences, rather than interactions between the structured core scaffold nucleoporins, mediate the assembly of the inner ring complex and its attachment to the NPC coat. X-ray crystallographic analysis of these scaffold nucleoporins revealed the molecular details of their interactions with the flexible linker sequences and enabled construction of full-length atomic structures. By docking these structures into the cryoelectron tomographic reconstruction of the intact human NPC and validating their placement with our nucleoporin interactome, we built a composite structure of the NPC symmetric core that contains ~320,000 residues and accounts for ~56 megadaltons of the NPC's structured mass. Our approach provides a paradigm for the structure determination of similarly complex macromolecular assemblies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Daniel H -- Stuwe, Tobias -- Schilbach, Sandra -- Rundlet, Emily J -- Perriches, Thibaud -- Mobbs, George -- Fan, Yanbin -- Thierbach, Karsten -- Huber, Ferdinand M -- Collins, Leslie N -- Davenport, Andrew M -- Jeon, Young E -- Hoelz, Andre -- 5 T32 GM07616/GM/NIGMS NIH HHS/ -- ACB-12002/PHS HHS/ -- AGM-12006/PHS HHS/ -- R01 GM111461/GM/NIGMS NIH HHS/ -- R01-GM111461/GM/NIGMS NIH HHS/ -- T32 GM007616/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):aaf1015. doi: 10.1126/science.aaf1015.

    Description: The dynamic properties of foldamers, synthetic molecules that mimic folded biomolecules, have mainly been explored in free solution. We report on the design, synthesis, and conformational behavior of photoresponsive foldamers bound in a phospholipid bilayer akin to a biological membrane phase. These molecules contain a chromophore, which can be switched between two configurations by different wavelengths of light, attached to a helical synthetic peptide that both promotes membrane insertion and communicates conformational change along its length. Light-induced structural changes in the chromophore are translated into global conformational changes, which are detected by monitoring the solid-state (19)F nuclear magnetic resonance signals of a remote fluorine-containing residue located 1 to 2 nanometers away. The behavior of the foldamers in the membrane phase is similar to that of analogous compounds in organic solvents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Poli, Matteo -- Zawodny, Wojciech -- Quinonero, Ophelie -- Lorch, Mark -- Webb, Simon J -- Clayden, Jonathan -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):575-80. doi: 10.1126/science.aad8352.

    Description: T cell-mediated destruction of insulin-producing beta cells in the pancreas causes type 1 diabetes (T1D). CD4 T cell responses play a central role in beta cell destruction, but the identity of the epitopes recognized by pathogenic CD4 T cells remains unknown. We found that diabetes-inducing CD4 T cell clones isolated from nonobese diabetic mice recognize epitopes formed by covalent cross-linking of proinsulin peptides to other peptides present in beta cell secretory granules. These hybrid insulin peptides (HIPs) are antigenic for CD4 T cells and can be detected by mass spectrometry in beta cells. CD4 T cells from the residual pancreatic islets of two organ donors who had T1D also recognize HIPs. Autoreactive T cells targeting hybrid peptides may explain how immune tolerance is broken in T1D.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Delong, Thomas -- Wiles, Timothy A -- Baker, Rocky L -- Bradley, Brenda -- Barbour, Gene -- Reisdorph, Richard -- Armstrong, Michael -- Powell, Roger L -- Reisdorph, Nichole -- Kumar, Nitesh -- Elso, Colleen M -- DeNicola, Megan -- Bottino, Rita -- Powers, Alvin C -- Harlan, David M -- Kent, Sally C -- Mannering, Stuart I -- Haskins, Kathryn -- 1K01DK094941/DK/NIDDK NIH HHS/ -- 1R01DK081166/DK/NIDDK NIH HHS/ -- 5U01DK89572/DK/NIDDK NIH HHS/ -- DK104211/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):711-4. doi: 10.1126/science.aad2791.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbiology, University of Colorado School of Medicine, Denver, Anschutz Medical Campus, Aurora, CO 80045, USA. thomas.delong@ucdenver.edu katie.haskins@ucdenver.edu. ; Department of Immunology and Microbiology, University of Colorado School of Medicine, Denver, Anschutz Medical Campus, Aurora, CO 80045, USA. ; Pharmaceutical Sciences, University of Colorado School of Medicine, Aurora, CO 80045, USA. ; Immunology and Diabetes Unit, St. Vincent's Institute of Medical Research, 9 Princes Street, Fitzroy, Victoria 3065, Australia. ; Department of Medicine, Diabetes Division, Diabetes Center of Excellence, University of Massachusetts Medical School, Worcester, MA, USA. ; Institute of Cellular Therapeutics, Allegheny-Singer Research Institute, Allegheny Health Network, Pittsburgh, PA, USA. ; Division of Diabetes, Endocrinology, and Metabolism, Department of Medicine, and Department of Molecular Physiology and Biophysics, Vanderbilt University Medical Center, Nashville, TN, USA.

    Description: As tumors grow, they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intratumor heterogeneity (ITH) on antitumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden and overall survival in primary lung adenocarcinomas. CD8(+)tumor-infiltrating lymphocytes reactive to clonal neoantigens were identified in early-stage non-small cell lung cancer and expressed high levels of PD-1. Sensitivity to PD-1 and CTLA-4 blockade in patients with advanced NSCLC and melanoma was enhanced in tumors enriched for clonal neoantigens. T cells recognizing clonal neoantigens were detectable in patients with durable clinical benefit. Cytotoxic chemotherapy-induced subclonal neoantigens, contributing to an increased mutational load, were enriched in certain poor responders. These data suggest that neoantigen heterogeneity may influence immune surveillance and support therapeutic developments targeting clonal neoantigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGranahan, Nicholas -- Furness, Andrew J S -- Rosenthal, Rachel -- Ramskov, Sofie -- Lyngaa, Rikke -- Saini, Sunil Kumar -- Jamal-Hanjani, Mariam -- Wilson, Gareth A -- Birkbak, Nicolai J -- Hiley, Crispin T -- Watkins, Thomas B K -- Shafi, Seema -- Murugaesu, Nirupa -- Mitter, Richard -- Akarca, Ayse U -- Linares, Joseph -- Marafioti, Teresa -- Henry, Jake Y -- Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Schadendorf, Dirk -- Garraway, Levi A -- Makarov, Vladimir -- Rizvi, Naiyer A -- Snyder, Alexandra -- Hellmann, Matthew D -- Merghoub, Taha -- Wolchok, Jedd D -- Shukla, Sachet A -- Wu, Catherine J -- Peggs, Karl S -- Chan, Timothy A -- Hadrup, Sine R -- Quezada, Sergio A -- Swanton, Charles -- 12100/Cancer Research UK/United Kingdom -- 1R01CA155010-02/CA/NCI NIH HHS/ -- 1R01CA182461-01/CA/NCI NIH HHS/ -- 1R01CA184922-01/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1463-9. doi: 10.1126/science.aaf1490.

    Description: Brazil has experienced an unprecedented epidemic of Zika virus (ZIKV), with ~30,000 cases reported to date. ZIKV was first detected in Brazil in May 2015, and cases of microcephaly potentially associated with ZIKV infection were identified in November 2015. We performed next-generation sequencing to generate seven Brazilian ZIKV genomes sampled from four self-limited cases, one blood donor, one fatal adult case, and one newborn with microcephaly and congenital malformations. Results of phylogenetic and molecular clock analyses show a single introduction of ZIKV into the Americas, which we estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil. The estimated date of origin coincides with an increase in air passengers to Brazil from ZIKV-endemic areas, as well as with reported outbreaks in the Pacific Islands. ZIKV genomes from Brazil are phylogenetically interspersed with those from other South American and Caribbean countries. Mapping mutations onto existing structural models revealed the context of viral amino acid changes present in the outbreak lineage; however, no shared amino acid changes were found among the three currently available virus genomes from microcephaly cases. Municipality-level incidence data indicate that reports of suspected microcephaly in Brazil best correlate with ZIKV incidence around week 17 of pregnancy, although this correlation does not demonstrate causation. Our genetic description and analysis of ZIKV isolates in Brazil provide a baseline for future studies of the evolution and molecular epidemiology of this emerging virus in the Americas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faria, Nuno Rodrigues -- Azevedo, Raimunda do Socorro da Silva -- Kraemer, Moritz U G -- Souza, Renato -- Cunha, Mariana Sequetin -- Hill, Sarah C -- Theze, Julien -- Bonsall, Michael B -- Bowden, Thomas A -- Rissanen, Ilona -- Rocco, Iray Maria -- Nogueira, Juliana Silva -- Maeda, Adriana Yurika -- Vasami, Fernanda Giseli da Silva -- Macedo, Fernando Luiz de Lima -- Suzuki, Akemi -- Rodrigues, Sueli Guerreiro -- Cruz, Ana Cecilia Ribeiro -- Nunes, Bruno Tardeli -- Medeiros, Daniele Barbosa de Almeida -- Rodrigues, Daniela Sueli Guerreiro -- Nunes Queiroz, Alice Louize -- da Silva, Eliana Vieira Pinto -- Henriques, Daniele Freitas -- Travassos da Rosa, Elisabeth Salbe -- de Oliveira, Consuelo Silva -- Martins, Livia Caricio -- Vasconcelos, Helena Baldez -- Casseb, Livia Medeiros Neves -- Simith, Darlene de Brito -- Messina, Jane P -- Abade, Leandro -- Lourenco, Jose -- Carlos Junior Alcantara, Luiz -- de Lima, Maricelia Maia -- Giovanetti, Marta -- Hay, Simon I -- de Oliveira, Rodrigo Santos -- Lemos, Poliana da Silva -- de Oliveira, Layanna Freitas -- de Lima, Clayton Pereira Silva -- da Silva, Sandro Patroca -- de Vasconcelos, Janaina Mota -- Franco, Luciano -- Cardoso, Jedson Ferreira -- Vianez-Junior, Joao Lidio da Silva Goncalves -- Mir, Daiana -- Bello, Gonzalo -- Delatorre, Edson -- Khan, Kamran -- Creatore, Marisa -- Coelho, Giovanini Evelim -- de Oliveira, Wanderson Kleber -- Tesh, Robert -- Pybus, Oliver G -- Nunes, Marcio R T -- Vasconcelos, Pedro F C -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095066/Wellcome Trust/United Kingdom -- 102427/Wellcome Trust/United Kingdom -- MR/L009528/1/Medical Research Council/United Kingdom -- R24 AT 120942/AT/NCCIH NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):345-9. doi: 10.1126/science.aaf5036.

    Description: Ebola virus causes hemorrhagic fever with a high case fatality rate for which there is no approved therapy. Two human monoclonal antibodies, mAb100 and mAb114, in combination, protect nonhuman primates against all signs of Ebola virus disease, including viremia. Here, we demonstrate that mAb100 recognizes the base of the Ebola virus glycoprotein (GP) trimer, occludes access to the cathepsin-cleavage loop, and prevents the proteolytic cleavage of GP that is required for virus entry. We show that mAb114 interacts with the glycan cap and inner chalice of GP, remains associated after proteolytic removal of the glycan cap, and inhibits binding of cleaved GP to its receptor. These results define the basis of neutralization for two protective antibodies and may facilitate development of therapies and vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Misasi, John -- Gilman, Morgan S A -- Kanekiyo, Masaru -- Gui, Miao -- Cagigi, Alberto -- Mulangu, Sabue -- Corti, Davide -- Ledgerwood, Julie E -- Lanzavecchia, Antonio -- Cunningham, James -- Muyembe-Tamfun, Jean Jacques -- Baxa, Ulrich -- Graham, Barney S -- Xiang, Ye -- Sullivan, Nancy J -- McLellan, Jason S -- 5K08AI079381/AI/NIAID NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- T32GM008704/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1343-6. doi: 10.1126/science.aad6117.

    Description: With functions that range from cell envelope structure to signal transduction and transport, lipoproteins constitute 2 to 3% of bacterial genomes and play critical roles in bacterial physiology, pathogenicity, and antibiotic resistance. Lipoproteins are synthesized with a signal peptide securing them to the cytoplasmic membrane with the lipoprotein domain in the periplasm or outside the cell. Posttranslational processing requires a signal peptidase II (LspA) that removes the signal peptide. Here, we report the crystal structure of LspA from Pseudomonas aeruginosa complexed with the antimicrobial globomycin at 2.8 angstrom resolution. Mutagenesis studies identify LspA as an aspartyl peptidase.

    Description: Splicing of precursor messenger RNA is accomplished by a dynamic megacomplex known as the spliceosome. Assembly of a functional spliceosome requires a preassembled U4/U6.U5 tri-snRNP complex, which comprises the U5 small nuclear ribonucleoprotein (snRNP), the U4 and U6 small nuclear RNA (snRNA) duplex, and a number of protein factors. Here we report the three-dimensional structure of a Saccharomyces cerevisiae U4/U6.U5 tri-snRNP at an overall resolution of 3.8 angstroms by single-particle electron cryomicroscopy. The local resolution for the core regions of the tri-snRNP reaches 3.0 to 3.5 angstroms, allowing construction of a refined atomic model. Our structure contains U5 snRNA, the extensively base-paired U4/U6 snRNA, and 30 proteins including Prp8 and Snu114, which amount to 8495 amino acids and 263 nucleotides with a combined molecular mass of ~1 megadalton. The catalytic nucleotide U80 from U6 snRNA exists in an inactive conformation, stabilized by its base-pairing interactions with U4 snRNA and protected by Prp3. Pre-messenger RNA is bound in the tri-snRNP through base-pairing interactions with U6 snRNA and loop I of U5 snRNA. This structure, together with that of the spliceosome, reveals the molecular choreography of the snRNAs in the activation process of the spliceosomal ribozyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wan, Ruixue -- Yan, Chuangye -- Bai, Rui -- Wang, Lin -- Huang, Min -- Wong, Catherine C L -- Shi, Yigong -- New York, N.Y. -- Science. 2016 Jan 29;351(6272):466-75. doi: 10.1126/science.aad6466.

    Description: Drug resistance compromises control of malaria. Here, we show that resistance to a commonly used antimalarial medication, atovaquone, is apparently unable to spread. Atovaquone pressure selects parasites with mutations in cytochrome b, a respiratory protein with low but essential activity in the mammalian blood phase of the parasite life cycle. Resistance mutations rescue parasites from the drug but later prove lethal in the mosquito phase, where parasites require full respiration. Unable to respire efficiently, resistant parasites fail to complete mosquito development, arresting their life cycle. Because cytochrome b is encoded by the maternally inherited parasite mitochondrion, even outcrossing with wild-type strains cannot facilitate spread of resistance. Lack of transmission suggests that resistance will be unable to spread in the field, greatly enhancing the utility of atovaquone in malaria control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodman, Christopher D -- Siregar, Josephine E -- Mollard, Vanessa -- Vega-Rodriguez, Joel -- Syafruddin, Din -- Matsuoka, Hiroyuki -- Matsuzaki, Motomichi -- Toyama, Tomoko -- Sturm, Angelika -- Cozijnsen, Anton -- Jacobs-Lorena, Marcelo -- Kita, Kiyoshi -- Marzuki, Sangkot -- McFadden, Geoffrey I -- AI031478/AI/NIAID NIH HHS/ -- RR00052/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):349-53. doi: 10.1126/science.aad9279.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of BioSciences, University of Melbourne, Melbourne, VIC 3010, Australia. gim@unimelb.edu.au deang@unimelb.edu.au. ; School of BioSciences, University of Melbourne, Melbourne, VIC 3010, Australia.

    Description: The U4/U6.U5 triple small nuclear ribonucleoprotein (tri-snRNP) is a major spliceosome building block. We obtained a three-dimensional structure of the 1.8-megadalton human tri-snRNP at a resolution of 7 angstroms using single-particle cryo-electron microscopy (cryo-EM). We fit all known high-resolution structures of tri-snRNP components into the EM density map and validated them by protein cross-linking. Our model reveals how the spatial organization of Brr2 RNA helicase prevents premature U4/U6 RNA unwinding in isolated human tri-snRNPs and how the ubiquitin C-terminal hydrolase-like protein Sad1 likely tethers the helicase Brr2 to its preactivation position. Comparison of our model with cryo-EM three-dimensional structures of the Saccharomyces cerevisiae tri-snRNP and Schizosaccharomyces pombe spliceosome indicates that Brr2 undergoes a marked conformational change during spliceosome activation, and that the scaffolding protein Prp8 is also rearranged to accommodate the spliceosome's catalytic RNA network.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Agafonov, Dmitry E -- Kastner, Berthold -- Dybkov, Olexandr -- Hofele, Romina V -- Liu, Wen-Ti -- Urlaub, Henning -- Luhrmann, Reinhard -- Stark, Holger -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1416-20. doi: 10.1126/science.aad2085.

    Description: Poly(ethylene terephthalate) (PET) is used extensively worldwide in plastic products, and its accumulation in the environment has become a global concern. Because the ability to enzymatically degrade PET has been thought to be limited to a few fungal species, biodegradation is not yet a viable remediation or recycling strategy. By screening natural microbial communities exposed to PET in the environment, we isolated a novel bacterium, Ideonella sakaiensis 201-F6, that is able to use PET as its major energy and carbon source. When grown on PET, this strain produces two enzymes capable of hydrolyzing PET and the reaction intermediate, mono(2-hydroxyethyl) terephthalic acid. Both enzymes are required to enzymatically convert PET efficiently into its two environmentally benign monomers, terephthalic acid and ethylene glycol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Shosuke -- Hiraga, Kazumi -- Takehana, Toshihiko -- Taniguchi, Ikuo -- Yamaji, Hironao -- Maeda, Yasuhito -- Toyohara, Kiyotsuna -- Miyamoto, Kenji -- Kimura, Yoshiharu -- Oda, Kohei -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1196-9. doi: 10.1126/science.aad6359.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Biology, Faculty of Textile Science, Kyoto Institute of Technology, Matsugasaki, Sakyo-ku, Kyoto 606-8585, Japan.

    Description: Oncogenes are activated through well-known chromosomal alterations such as gene fusion, translocation, and focal amplification. In light of recent evidence that the control of key genes depends on chromosome structures called insulated neighborhoods, we investigated whether proto-oncogenes occur within these structures and whether oncogene activation can occur via disruption of insulated neighborhood boundaries in cancer cells. We mapped insulated neighborhoods in T cell acute lymphoblastic leukemia (T-ALL) and found that tumor cell genomes contain recurrent microdeletions that eliminate the boundary sites of insulated neighborhoods containing prominent T-ALL proto-oncogenes. Perturbation of such boundaries in nonmalignant cells was sufficient to activate proto-oncogenes. Mutations affecting chromosome neighborhood boundaries were found in many types of cancer. Thus, oncogene activation can occur via genetic alterations that disrupt insulated neighborhoods in malignant cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hnisz, Denes -- Weintraub, Abraham S -- Day, Daniel S -- Valton, Anne-Laure -- Bak, Rasmus O -- Li, Charles H -- Goldmann, Johanna -- Lajoie, Bryan R -- Fan, Zi Peng -- Sigova, Alla A -- Reddy, Jessica -- Borges-Rivera, Diego -- Lee, Tong Ihn -- Jaenisch, Rudolf -- Porteus, Matthew H -- Dekker, Job -- Young, Richard A -- AI120766/AI/NIAID NIH HHS/ -- CA109901/CA/NCI NIH HHS/ -- HG002668/HG/NHGRI NIH HHS/ -- MH104610/MH/NIMH NIH HHS/ -- NS088538/NS/NINDS NIH HHS/ -- R01 GM 112720/GM/NIGMS NIH HHS/ -- R01 HG002668/HG/NHGRI NIH HHS/ -- R01 HG003143/HG/NHGRI NIH HHS/ -- R01 MH104610/MH/NIMH NIH HHS/ -- U01 DA 040588/DA/NIDA NIH HHS/ -- U01 HG007910/HG/NHGRI NIH HHS/ -- U01 R01 AI 117839/AI/NIAID NIH HHS/ -- U54 CA193419/CA/NCI NIH HHS/ -- U54 DK107980/DK/NIDDK NIH HHS/ -- U54 HG007010/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1454-8. doi: 10.1126/science.aad9024.

    Description: Sequencing of exomes and genomes has revealed abundant genetic variation affecting the coding sequences of human transcription factors (TFs), but the consequences of such variation remain largely unexplored. We developed a computational, structure-based approach to evaluate TF variants for their impact on DNA binding activity and used universal protein-binding microarrays to assay sequence-specific DNA binding activity across 41 reference and 117 variant alleles found in individuals of diverse ancestries and families with Mendelian diseases. We found 77 variants in 28 genes that affect DNA binding affinity or specificity and identified thousands of rare alleles likely to alter the DNA binding activity of human sequence-specific TFs. Our results suggest that most individuals have unique repertoires of TF DNA binding activities, which may contribute to phenotypic variation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4825693/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4825693/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barrera, Luis A -- Vedenko, Anastasia -- Kurland, Jesse V -- Rogers, Julia M -- Gisselbrecht, Stephen S -- Rossin, Elizabeth J -- Woodard, Jaie -- Mariani, Luca -- Kock, Kian Hong -- Inukai, Sachi -- Siggers, Trevor -- Shokri, Leila -- Gordan, Raluca -- Sahni, Nidhi -- Cotsapas, Chris -- Hao, Tong -- Yi, Song -- Kellis, Manolis -- Daly, Mark J -- Vidal, Marc -- Hill, David E -- Bulyk, Martha L -- P50 HG004233/HG/NHGRI NIH HHS/ -- R01 HG003985/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1450-4. doi: 10.1126/science.aad2257.

    Description: Antibiotic treatment has two conflicting effects: the desired, immediate effect of inhibiting bacterial growth and the undesired, long-term effect of promoting the evolution of resistance. Although these contrasting outcomes seem inextricably linked, recent work has revealed several ways by which antibiotics can be combined to inhibit bacterial growth while, counterintuitively, selecting against resistant mutants. Decoupling treatment efficacy from the risk of resistance can be achieved by exploiting specific interactions between drugs, and the ways in which resistance mutations to a given drug can modulate these interactions or increase the sensitivity of the bacteria to other compounds. Although their practical application requires much further development and validation, and relies on advances in genomic diagnostics, these discoveries suggest novel paradigms that may restrict or even reverse the evolution of resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baym, Michael -- Stone, Laura K -- Kishony, Roy -- R01-GM081617/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 1;351(6268):aad3292. doi: 10.1126/science.aad3292.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Systems Biology, Harvard Medical School, Boston, MA, USA. ; Department of Systems Biology, Harvard Medical School, Boston, MA, USA.

    Description: SH3 and multiple ankyrin repeat domains 3 (SHANK3) haploinsufficiency is causative for the neurological features of Phelan-McDermid syndrome (PMDS), including a high risk of autism spectrum disorder (ASD). We used unbiased, quantitative proteomics to identify changes in the phosphoproteome of Shank3-deficient neurons. Down-regulation of protein kinase B (PKB/Akt)-mammalian target of rapamycin complex 1 (mTORC1) signaling resulted from enhanced phosphorylation and activation of serine/threonine protein phosphatase 2A (PP2A) regulatory subunit, B56beta, due to increased steady-state levels of its kinase, Cdc2-like kinase 2 (CLK2). Pharmacological and genetic activation of Akt or inhibition of CLK2 relieved synaptic deficits in Shank3-deficient and PMDS patient-derived neurons. CLK2 inhibition also restored normal sociability in a Shank3-deficient mouse model. Our study thereby provides a novel mechanistic and potentially therapeutic understanding of deregulated signaling downstream of Shank3 deficiency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bidinosti, Michael -- Botta, Paolo -- Kruttner, Sebastian -- Proenca, Catia C -- Stoehr, Natacha -- Bernhard, Mario -- Fruh, Isabelle -- Mueller, Matthias -- Bonenfant, Debora -- Voshol, Hans -- Carbone, Walter -- Neal, Sarah J -- McTighe, Stephanie M -- Roma, Guglielmo -- Dolmetsch, Ricardo E -- Porter, Jeffrey A -- Caroni, Pico -- Bouwmeester, Tewis -- Luthi, Andreas -- Galimberti, Ivan -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1199-203. doi: 10.1126/science.aad5487.

    Description: Bacterial adaptive immunity and genome engineering involving the CRISPR (clustered regularly interspaced short palindromic repeats)-associated (Cas) protein Cas9 begin with RNA-guided DNA unwinding to form an RNA-DNA hybrid and a displaced DNA strand inside the protein. The role of this R-loop structure in positioning each DNA strand for cleavage by the two Cas9 nuclease domains is unknown. We determine molecular structures of the catalytically active Streptococcus pyogenes Cas9 R-loop that show the displaced DNA strand located near the RuvC nuclease domain active site. These protein-DNA interactions, in turn, position the HNH nuclease domain adjacent to the target DNA strand cleavage site in a conformation essential for concerted DNA cutting. Cas9 bends the DNA helix by 30 degrees , providing the structural distortion needed for R-loop formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Fuguo -- Taylor, David W -- Chen, Janice S -- Kornfeld, Jack E -- Zhou, Kaihong -- Thompson, Aubri J -- Nogales, Eva -- Doudna, Jennifer A -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Feb 19;351(6275):867-71. doi: 10.1126/science.aad8282.

    Description: Induction of broadly neutralizing antibodies (bnAbs) is a major HIV vaccine goal. Germline-targeting immunogens aim to initiate bnAb induction by activating bnAb germline precursor B cells. Critical unmet challenges are to determine whether bnAb precursor naive B cells bind germline-targeting immunogens and occur at sufficient frequency in humans for reliable vaccine responses. Using deep mutational scanning and multitarget optimization, we developed a germline-targeting immunogen (eOD-GT8) for diverse VRC01-class bnAbs. We then used the immunogen to isolate VRC01-class precursor naive B cells from HIV-uninfected donors. Frequencies of true VRC01-class precursors, their structures, and their eOD-GT8 affinities support this immunogen as a candidate human vaccine prime. These methods could be applied to germline targeting for other classes of HIV bnAbs and for Abs to other pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4872700/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4872700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jardine, Joseph G -- Kulp, Daniel W -- Havenar-Daughton, Colin -- Sarkar, Anita -- Briney, Bryan -- Sok, Devin -- Sesterhenn, Fabian -- Ereno-Orbea, June -- Kalyuzhniy, Oleksandr -- Deresa, Isaiah -- Hu, Xiaozhen -- Spencer, Skye -- Jones, Meaghan -- Georgeson, Erik -- Adachi, Yumiko -- Kubitz, Michael -- deCamp, Allan C -- Julien, Jean-Philippe -- Wilson, Ian A -- Burton, Dennis R -- Crotty, Shane -- Schief, William R -- P01 AI094419/AI/NIAID NIH HHS/ -- P01 AI110657/AI/NIAID NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1458-63. doi: 10.1126/science.aad9195.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbial Science, The Scripps Research Institute, La Jolla, CA 92037, USA.

    Description: The lung is constantly exposed to environmental atmospheric cues. How it senses and responds to these cues is poorly defined. Here, we show that Roundabout receptor (Robo) genes are expressed in pulmonary neuroendocrine cells (PNECs), a rare, innervated epithelial population. Robo inactivation in mouse lung results in an inability of PNECs to cluster into sensory organoids and triggers increased neuropeptide production upon exposure to air. Excess neuropeptides lead to an increase in immune infiltrates, which in turn remodel the matrix and irreversibly simplify the alveoli. We demonstrate in vivo that PNECs act as precise airway sensors that elicit immune responses via neuropeptides. These findings suggest that the PNEC and neuropeptide abnormalities documented in a wide array of pulmonary diseases may profoundly affect symptoms and progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Branchfield, Kelsey -- Nantie, Leah -- Verheyden, Jamie M -- Sui, Pengfei -- Wienhold, Mark D -- Sun, Xin -- 5T32AI007635/AI/NIAID NIH HHS/ -- HL097134/HL/NHLBI NIH HHS/ -- HL122406/HL/NHLBI NIH HHS/ -- R01 HL113870/HL/NHLBI NIH HHS/ -- T32 GM007133/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):707-10. doi: 10.1126/science.aad7969.

    Description: The "cancerized field" concept posits that cancer-prone cells in a given tissue share an oncogenic mutation, but only discreet clones within the field initiate tumors. Most benign nevi carry oncogenic BRAF(V600E) mutations but rarely become melanoma. The zebrafish crestin gene is expressed embryonically in neural crest progenitors (NCPs) and specifically reexpressed in melanoma. Live imaging of transgenic zebrafish crestin reporters shows that within a cancerized field (BRAF(V600E)-mutant; p53-deficient), a single melanocyte reactivates the NCP state, revealing a fate change at melanoma initiation in this model. NCP transcription factors, including sox10, regulate crestin expression. Forced sox10 overexpression in melanocytes accelerated melanoma formation, which is consistent with activation of NCP genes and super-enhancers leading to melanoma. Our work highlights NCP state reemergence as a key event in melanoma initiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaufman, Charles K -- Mosimann, Christian -- Fan, Zi Peng -- Yang, Song -- Thomas, Andrew J -- Ablain, Julien -- Tan, Justin L -- Fogley, Rachel D -- van Rooijen, Ellen -- Hagedorn, Elliott J -- Ciarlo, Christie -- White, Richard M -- Matos, Dominick A -- Puller, Ann-Christin -- Santoriello, Cristina -- Liao, Eric C -- Young, Richard A -- Zon, Leonard I -- HG002668/HG/NHGRI NIH HHS/ -- K08 AR061071/AR/NIAMS NIH HHS/ -- R01 CA103846/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 29;351(6272):aad2197. doi: 10.1126/science.aad2197.

    Description: Type IVa pili are filamentous cell surface structures observed in many bacteria. They pull cells forward by extending, adhering to surfaces, and then retracting. We used cryo-electron tomography of intact Myxococcus xanthus cells to visualize type IVa pili and the protein machine that assembles and retracts them (the type IVa pilus machine, or T4PM) in situ, in both the piliated and nonpiliated states, at a resolution of 3 to 4 nanometers. We found that T4PM comprises an outer membrane pore, four interconnected ring structures in the periplasm and cytoplasm, a cytoplasmic disc and dome, and a periplasmic stem. By systematically imaging mutants lacking defined T4PM proteins or with individual proteins fused to tags, we mapped the locations of all 10 T4PM core components and the minor pilins, thereby providing insights into pilus assembly, structure, and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Yi-Wei -- Rettberg, Lee A -- Treuner-Lange, Anke -- Iwasa, Janet -- Sogaard-Andersen, Lotte -- Jensen, Grant J -- R01 GM094800B/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):aad2001. doi: 10.1126/science.aad2001.

    Description: Plant immunity against foreign gene invasion takes advantage of posttranscriptional gene silencing (PTGS). How plants elaborately avert inappropriate PTGS of endogenous coding genes remains unclear. We demonstrate in Arabidopsis that both 5'-3' and 3'-5' cytoplasmic RNA decay pathways act as repressors of transgene and endogenous PTGS. Disruption of bidirectional cytoplasmic RNA decay leads to pleiotropic developmental defects and drastic transcriptomic alterations, which are substantially rescued by PTGS mutants. Upon dysfunction of bidirectional RNA decay, a large number of 21- to 22-nucleotide endogenous small interfering RNAs are produced from coding transcripts, including multiple microRNA targets, which could interfere with their cognate gene expression and functions. This study highlights the risk of unwanted PTGS and identifies cytoplasmic RNA decay pathways as safeguards of plant transcriptome and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Xinyan -- Zhu, Ying -- Liu, Xiaodan -- Hong, Xinyu -- Xu, Yang -- Zhu, Ping -- Shen, Yang -- Wu, Huihui -- Ji, Yusi -- Wen, Xing -- Zhang, Chen -- Zhao, Qiong -- Wang, Yichuan -- Lu, Jian -- Guo, Hongwei -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):120-3. doi: 10.1126/science.aaa2618.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Protein and Plant Gene Research, College of Life Sciences, Peking University, Beijing 100871, China. ; Biodynamic Optical Imaging Center, School of Life Sciences, Peking University, Beijing 100871, China. ; Peking-Tsinghua Center for Life Sciences, Peking University, Beijing 100871, China. ; State Key Laboratory of Protein and Plant Gene Research, College of Life Sciences, Peking University, Beijing 100871, China.

    Description: Although the genes essential for life have been identified in less complex model organisms, their elucidation in human cells has been hindered by technical barriers. We used extensive mutagenesis in haploid human cells to identify approximately 2000 genes required for optimal fitness under culture conditions. To study the principles of genetic interactions in human cells, we created a synthetic lethality network focused on the secretory pathway based exclusively on mutations. This revealed a genetic cross-talk governing Golgi homeostasis, an additional subunit of the human oligosaccharyltransferase complex, and a phosphatidylinositol 4-kinase beta adaptor hijacked by viruses. The synthetic lethality map parallels observations made in yeast and projects a route forward to reveal genetic networks in diverse aspects of human cell biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blomen, Vincent A -- Majek, Peter -- Jae, Lucas T -- Bigenzahn, Johannes W -- Nieuwenhuis, Joppe -- Staring, Jacqueline -- Sacco, Roberto -- van Diemen, Ferdy R -- Olk, Nadine -- Stukalov, Alexey -- Marceau, Caleb -- Janssen, Hans -- Carette, Jan E -- Bennett, Keiryn L -- Colinge, Jacques -- Superti-Furga, Giulio -- Brummelkamp, Thijn R -- New York, N.Y. -- Science. 2015 Nov 27;350(6264):1092-6. doi: 10.1126/science.aac7557.

    Description: Immune checkpoint inhibitors, which unleash a patient's own T cells to kill tumors, are revolutionizing cancer treatment. To unravel the genomic determinants of response to this therapy, we used whole-exome sequencing of non-small cell lung cancers treated with pembrolizumab, an antibody targeting programmed cell death-1 (PD-1). In two independent cohorts, higher nonsynonymous mutation burden in tumors was associated with improved objective response, durable clinical benefit, and progression-free survival. Efficacy also correlated with the molecular smoking signature, higher neoantigen burden, and DNA repair pathway mutations; each factor was also associated with mutation burden. In one responder, neoantigen-specific CD8+ T cell responses paralleled tumor regression, suggesting that anti-PD-1 therapy enhances neoantigen-specific T cell reactivity. Our results suggest that the genomic landscape of lung cancers shapes response to anti-PD-1 therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rizvi, Naiyer A -- Hellmann, Matthew D -- Snyder, Alexandra -- Kvistborg, Pia -- Makarov, Vladimir -- Havel, Jonathan J -- Lee, William -- Yuan, Jianda -- Wong, Phillip -- Ho, Teresa S -- Miller, Martin L -- Rekhtman, Natasha -- Moreira, Andre L -- Ibrahim, Fawzia -- Bruggeman, Cameron -- Gasmi, Billel -- Zappasodi, Roberta -- Maeda, Yuka -- Sander, Chris -- Garon, Edward B -- Merghoub, Taha -- Wolchok, Jedd D -- Schumacher, Ton N -- Chan, Timothy A -- K23 CA149079/CA/NCI NIH HHS/ -- P30 CA008748/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):124-8. doi: 10.1126/science.aaa1348.

    Description: The function of neural circuits depends on the generation of specific classes of neurons. Neural identity is typically established near the time when neurons exit the cell cycle to become postmitotic cells, and it is generally accepted that, once the identity of a neuron has been established, its fate is maintained throughout life. Here, we show that network activity dynamically modulates the properties of fast-spiking (FS) interneurons through the postmitotic expression of the transcriptional regulator Er81. In the adult cortex, Er81 protein levels define a spectrum of FS basket cells with different properties, whose relative proportions are, however, continuously adjusted in response to neuronal activity. Our findings therefore suggest that interneuron properties are malleable in the adult cortex, at least to a certain extent.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4702376/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4702376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehorter, Nathalie -- Ciceri, Gabriele -- Bartolini, Giorgia -- Lim, Lynette -- del Pino, Isabel -- Marin, Oscar -- 103714MA/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Sep 11;349(6253):1216-20. doi: 10.1126/science.aab3415.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MRC Centre for Developmental Neurobiology, Medical Research Council, New Hunt's House, Guy's Campus, King's College London, London SE1 1UL, UK.

    Description: A central process in evolution is the recruitment of genes to regulatory networks. We engineered immotile strains of the bacterium Pseudomonas fluorescens that lack flagella due to deletion of the regulatory gene fleQ. Under strong selection for motility, these bacteria consistently regained flagella within 96 hours via a two-step evolutionary pathway. Step 1 mutations increase intracellular levels of phosphorylated NtrC, a distant homolog of FleQ, which begins to commandeer control of the fleQ regulon at the cost of disrupting nitrogen uptake and assimilation. Step 2 is a switch-of-function mutation that redirects NtrC away from nitrogen uptake and toward its novel function as a flagellar regulator. Our results demonstrate that natural selection can rapidly rewire regulatory networks in very few, repeatable mutational steps.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, Tiffany B -- Mulley, Geraldine -- Dills, Alexander H -- Alsohim, Abdullah S -- McGuffin, Liam J -- Studholme, David J -- Silby, Mark W -- Brockhurst, Michael A -- Johnson, Louise J -- Jackson, Robert W -- BB/J015350/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/K003240/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT097835MF/Wellcome Trust/United Kingdom -- WT101650MA/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Feb 27;347(6225):1014-7. doi: 10.1126/science.1259145.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of Reading, Whiteknights, Reading RG6 6AJ, UK. ; Department of Biology, University of Massachusetts Dartmouth, 285 Old Westport Road, North Dartmouth, MA 02747, USA. ; School of Biological Sciences, University of Reading, Whiteknights, Reading RG6 6AJ, UK.

    Description: Sedimentary basins in eastern Africa preserve a record of continental rifting and contain important fossil assemblages for interpreting hominin evolution. However, the record of hominin evolution between 3 and 2.5 million years ago (Ma) is poorly documented in surface outcrops, particularly in Afar, Ethiopia. Here we present the discovery of a 2.84- to 2.58-million-year-old fossil and hominin-bearing sediments in the Ledi-Geraru research area of Afar, Ethiopia, that have produced the earliest record of the genus Homo. Vertebrate fossils record a faunal turnover indicative of more open and probably arid habitats than those reconstructed earlier in this region, which is in broad agreement with hypotheses addressing the role of environmental forcing in hominin evolution at this time. Geological analyses constrain depositional and structural models of Afar and date the LD 350-1 Homo mandible to 2.80 to 2.75 Ma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DiMaggio, Erin N -- Campisano, Christopher J -- Rowan, John -- Dupont-Nivet, Guillaume -- Deino, Alan L -- Bibi, Faysal -- Lewis, Margaret E -- Souron, Antoine -- Garello, Dominique -- Werdelin, Lars -- Reed, Kaye E -- Arrowsmith, J Ramon -- New York, N.Y. -- Science. 2015 Mar 20;347(6228):1355-9. doi: 10.1126/science.aaa1415.

    Description: Extremophiles, microorganisms thriving in extreme environmental conditions, must have proteins and nucleic acids that are stable at extremes of temperature and pH. The nonenveloped, rod-shaped virus SIRV2 (Sulfolobus islandicus rod-shaped virus 2) infects the hyperthermophilic acidophile Sulfolobus islandicus, which lives at 80 degrees C and pH 3. We have used cryo-electron microscopy to generate a three-dimensional reconstruction of the SIRV2 virion at ~4 angstrom resolution, which revealed a previously unknown form of virion organization. Although almost half of the capsid protein is unstructured in solution, this unstructured region folds in the virion into a single extended alpha helix that wraps around the DNA. The DNA is entirely in the A-form, which suggests a common mechanism with bacterial spores for protecting DNA in the most adverse environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DiMaio, Frank -- Yu, Xiong -- Rensen, Elena -- Krupovic, Mart -- Prangishvili, David -- Egelman, Edward H -- GM035269/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 May 22;348(6237):914-7. doi: 10.1126/science.aaa4181.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA. ; Department of Biochemistry and Molecular Genetics, University of Virginia, Charlottesville, VA 22908, USA. ; Institut Pasteur, Department of Microbiology, 25 rue du Dr. Roux, Paris 75015, France. ; Institut Pasteur, Department of Microbiology, 25 rue du Dr. Roux, Paris 75015, France. egelman@virginia.edu david.prangishvili@pasteur.fr. ; Department of Biochemistry and Molecular Genetics, University of Virginia, Charlottesville, VA 22908, USA. egelman@virginia.edu david.prangishvili@pasteur.fr.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25999507" target="_blank"〉PubMed〈/a〉

    Description: Strigolactones are naturally occurring signaling molecules that affect plant development, fungi-plant interactions, and parasitic plant infestations. We characterized the function of 11 strigolactone receptors from the parasitic plant Striga hermonthica using chemical and structural biology. We found a clade of polyspecific receptors, including one that is sensitive to picomolar concentrations of strigolactone. A crystal structure of a highly sensitive strigolactone receptor from Striga revealed a larger binding pocket than that of the Arabidopsis receptor, which could explain the increased range of strigolactone sensitivity. Thus, the sensitivity of Striga to strigolactones from host plants is driven by receptor sensitivity. By expressing strigolactone receptors in Arabidopsis, we developed a bioassay that can be used to identify chemicals and crops with altered strigolactone levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Toh, Shigeo -- Holbrook-Smith, Duncan -- Stogios, Peter J -- Onopriyenko, Olena -- Lumba, Shelley -- Tsuchiya, Yuichiro -- Savchenko, Alexei -- McCourt, Peter -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):203-7. doi: 10.1126/science.aac9476.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell and Systems Biology, University of Toronto, 25 Willcocks Street, Toronto M5S 3B2, Canada. ; Department of Chemical Engineering and Applied Chemistry, Banting and Best Department of Medical Research, University of Toronto, 200 College Street, Toronto M5S 3E5, Canada.

    Description: Adoptive cell therapy (ACT) is a highly personalized cancer therapy that involves administration to the cancer-bearing host of immune cells with direct anticancer activity. ACT using naturally occurring tumor-reactive lymphocytes has mediated durable, complete regressions in patients with melanoma, probably by targeting somatic mutations exclusive to each cancer. These results have expanded the reach of ACT to the treatment of common epithelial cancers. In addition, the ability to genetically engineer lymphocytes to express conventional T cell receptors or chimeric antigen receptors has further extended the successful application of ACT for cancer treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenberg, Steven A -- Restifo, Nicholas P -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):62-8. doi: 10.1126/science.aaa4967.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Surgery Branch, National Cancer Institute, Center for Cancer Research, National Institutes of Health, 9000 Rockville Pike, CRC Building, Room 3W-3940, Bethesda, MD 20892, USA. sar@nih.gov restifo@nih.gov.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25838374" target="_blank"〉PubMed〈/a〉

    Description: Some tissue types give rise to human cancers millions of times more often than other tissue types. Although this has been recognized for more than a century, it has never been explained. Here, we show that the lifetime risk of cancers of many different types is strongly correlated (0.81) with the total number of divisions of the normal self-renewing cells maintaining that tissue's homeostasis. These results suggest that only a third of the variation in cancer risk among tissues is attributable to environmental factors or inherited predispositions. The majority is due to "bad luck," that is, random mutations arising during DNA replication in normal, noncancerous stem cells. This is important not only for understanding the disease but also for designing strategies to limit the mortality it causes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446723/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446723/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomasetti, Cristian -- Vogelstein, Bert -- P30 CA006973/CA/NCI NIH HHS/ -- P30-CA006973/CA/NCI NIH HHS/ -- P50-CA62924/CA/NCI NIH HHS/ -- R01-CA57345/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37-CA43460/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jan 2;347(6217):78-81. doi: 10.1126/science.1260825.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biostatistics and Bioinformatics, Department of Oncology, Sidney Kimmel Cancer Center, Johns Hopkins University School of Medicine and Department of Biostatistics, Johns Hopkins Bloomberg School of Public Health, 550 North Broadway, Baltimore, MD 21205, USA. ctomasetti@jhu.edu vogelbe@jhmi.edu. ; Ludwig Center for Cancer Genetics and Therapeutics and Howard Hughes Medical Institute, Johns Hopkins Kimmel Cancer Center, 1650 Orleans Street, Baltimore, MD 21205, USA. ctomasetti@jhu.edu vogelbe@jhmi.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25554788" target="_blank"〉PubMed〈/a〉

    Description: Splicing of precursor messenger RNA is performed by the spliceosome. In the cryogenic electron microscopy structure of the yeast spliceosome, U5 small nuclear ribonucleoprotein acts as a central scaffold onto which U6 and U2 small nuclear RNAs (snRNAs) are intertwined to form a catalytic center next to Loop I of U5 snRNA. Magnesium ions are coordinated by conserved nucleotides in U6 snRNA. The intron lariat is held in place through base-pairing interactions with both U2 and U6 snRNAs, leaving the variable-length middle portion on the solvent-accessible surface of the catalytic center. The protein components of the spliceosome anchor both 5' and 3' ends of the U2 and U6 snRNAs away from the active site, direct the RNA sequences, and allow sufficient flexibility between the ends and the catalytic center. Thus, the spliceosome is in essence a protein-directed ribozyme, with the protein components essential for the delivery of critical RNA molecules into close proximity of one another at the right time for the splicing reaction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hang, Jing -- Wan, Ruixue -- Yan, Chuangye -- Shi, Yigong -- New York, N.Y. -- Science. 2015 Sep 11;349(6253):1191-8. doi: 10.1126/science.aac8159.

    Description: TREK-2 (KCNK10/K2P10), a two-pore domain potassium (K2P) channel, is gated by multiple stimuli such as stretch, fatty acids, and pH and by several drugs. However, the mechanisms that control channel gating are unclear. Here we present crystal structures of the human TREK-2 channel (up to 3.4 angstrom resolution) in two conformations and in complex with norfluoxetine, the active metabolite of fluoxetine (Prozac) and a state-dependent blocker of TREK channels. Norfluoxetine binds within intramembrane fenestrations found in only one of these two conformations. Channel activation by arachidonic acid and mechanical stretch involves conversion between these states through movement of the pore-lining helices. These results provide an explanation for TREK channel mechanosensitivity, regulation by diverse stimuli, and possible off-target effects of the serotonin reuptake inhibitor Prozac.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dong, Yin Yao -- Pike, Ashley C W -- Mackenzie, Alexandra -- McClenaghan, Conor -- Aryal, Prafulla -- Dong, Liang -- Quigley, Andrew -- Grieben, Mariana -- Goubin, Solenne -- Mukhopadhyay, Shubhashish -- Ruda, Gian Filippo -- Clausen, Michael V -- Cao, Lishuang -- Brennan, Paul E -- Burgess-Brown, Nicola A -- Sansom, Mark S P -- Tucker, Stephen J -- Carpenter, Elisabeth P -- 084655/Wellcome Trust/United Kingdom -- 092809/Z/10/Z/Wellcome Trust/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1256-9. doi: 10.1126/science.1261512.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Genomics Consortium, University of Oxford, Oxford OX3 7DQ, UK. ; Structural Genomics Consortium, University of Oxford, Oxford OX3 7DQ, UK.

    Description: It is unknown whether the human immune system frequently mounts a T cell response against mutations expressed by common epithelial cancers. Using a next-generation sequencing approach combined with high-throughput immunologic screening, we demonstrated that tumor-infiltrating lymphocytes (TILs) from 9 out of 10 patients with metastatic gastrointestinal cancers contained CD4(+) and/or CD8(+) T cells that recognized one to three neo-epitopes derived from somatic mutations expressed by the patient's own tumor. There were no immunogenic epitopes shared between these patients. However, we identified in one patient a human leukocyte antigen-C*08:02-restricted T cell receptor from CD8(+) TILs that targeted the KRAS(G12D) hotspot driver mutation found in many human cancers. Thus, a high frequency of patients with common gastrointestinal cancers harbor immunogenic mutations that can potentially be exploited for the development of highly personalized immunotherapies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tran, Eric -- Ahmadzadeh, Mojgan -- Lu, Yong-Chen -- Gros, Alena -- Turcotte, Simon -- Robbins, Paul F -- Gartner, Jared J -- Zheng, Zhili -- Li, Yong F -- Ray, Satyajit -- Wunderlich, John R -- Somerville, Robert P -- Rosenberg, Steven A -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 11;350(6266):1387-90. doi: 10.1126/science.aad1253.

    Description: The nonrandom distribution of meiotic recombination shapes heredity and genetic diversification. Theoretically, hotspots--favored sites of recombination initiation--either evolve rapidly toward extinction or are conserved, especially if they are chromosomal features under selective constraint, such as promoters. We tested these theories by comparing genome-wide recombination initiation maps from widely divergent Saccharomyces species. We find that hotspots frequently overlap with promoters in the species tested, and consequently, hotspot positions are well conserved. Remarkably, the relative strength of individual hotspots is also highly conserved, as are larger-scale features of the distribution of recombination initiation. This stability, not predicted by prior models, suggests that the particular shape of the yeast recombination landscape is adaptive and helps in understanding evolutionary dynamics of recombination in other species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4656144/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4656144/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lam, Isabel -- Keeney, Scott -- F31 GM097861/GM/NIGMS NIH HHS/ -- P30 CA008748/CA/NCI NIH HHS/ -- R01 GM058673/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Nov 20;350(6263):932-7. doi: 10.1126/science.aad0814.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Louis V.

    Description: Understanding the evolution of sex determination in plants requires identifying the mechanisms underlying the transition from monoecious plants, where male and female flowers coexist, to unisexual individuals found in dioecious species. We show that in melon and cucumber, the androecy gene controls female flower development and encodes a limiting enzyme of ethylene biosynthesis, ACS11. ACS11 is expressed in phloem cells connected to flowers programmed to become female, and ACS11 loss-of-function mutants lead to male plants (androecy). CmACS11 represses the expression of the male promoting gene CmWIP1 to control the development and the coexistence of male and female flowers in monoecious species. Because monoecy can lead to dioecy, we show how a combination of alleles of CmACS11 and CmWIP1 can create artificial dioecy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boualem, Adnane -- Troadec, Christelle -- Camps, Celine -- Lemhemdi, Afef -- Morin, Halima -- Sari, Marie-Agnes -- Fraenkel-Zagouri, Rina -- Kovalski, Irina -- Dogimont, Catherine -- Perl-Treves, Rafael -- Bendahmane, Abdelhafid -- New York, N.Y. -- Science. 2015 Nov 6;350(6261):688-91. doi: 10.1126/science.aac8370.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Recherche Agronomique (INRA), Institute of Plant Sciences Paris-Saclay, CNRS, Universite Paris-Sud, Universite d'Evry, Universite Paris-Diderot, Batiment 630, 91405, Orsay, France. ; Laboratoire de Chimie et Biochimie Pharmacologiques et Toxicologiques, CNRS, UMR 8601, Universite Rene Descartes, Paris, France. ; The Mina and Everard Goodman Faculty of Life Sciences, Bar-Ilan University, Ramat Gan, Israel. ; INRA, UR 1052, Unite de Genetique et d'Amelioration des Fruits et Legumes, BP 94, F-84143 Montfavet, France. ; Institut National de la Recherche Agronomique (INRA), Institute of Plant Sciences Paris-Saclay, CNRS, Universite Paris-Sud, Universite d'Evry, Universite Paris-Diderot, Batiment 630, 91405, Orsay, France. bendahm@evry.inra.fr.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26542573" target="_blank"〉PubMed〈/a〉

    Description: An important question in ecology is how mechanistic processes occurring among individuals drive large-scale patterns of community formation and change. Here we show that in two species of bluebirds, cycles of replacement of one by the other emerge as an indirect consequence of maternal influence on offspring behavior in response to local resource availability. Sampling across broad temporal and spatial scales, we found that western bluebirds, the more competitive species, bias the birth order of offspring by sex in a way that influences offspring aggression and dispersal, setting the stage for rapid increases in population density that ultimately result in the replacement of their sister species. Our results provide insight into how predictable community dynamics can occur despite the contingency of local behavioral interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duckworth, Renee A -- Belloni, Virginia -- Anderson, Samantha R -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):875-7. doi: 10.1126/science.1260154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ 85721, USA. rad3@email.arizona.edu. ; Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ 85721, USA.

    Description: Cope's rule proposes that animal lineages evolve toward larger body size over time. To test this hypothesis across all marine animals, we compiled a data set of body sizes for 17,208 genera of marine animals spanning the past 542 million years. Mean biovolume across genera has increased by a factor of 150 since the Cambrian, whereas minimum biovolume has decreased by less than a factor of 10, and maximum biovolume has increased by more than a factor of 100,000. Neutral drift from a small initial value cannot explain this pattern. Instead, most of the size increase reflects differential diversification across classes, indicating that the pattern does not reflect a simple scaling-up of widespread and persistent selection for larger size within populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heim, Noel A -- Knope, Matthew L -- Schaal, Ellen K -- Wang, Steve C -- Payne, Jonathan L -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):867-70. doi: 10.1126/science.1260065.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geological and Environmental Sciences, Stanford University, 450 Serra Mall, Stanford, CA 94305, USA. naheim@stanford.edu. ; Department of Geological and Environmental Sciences, Stanford University, 450 Serra Mall, Stanford, CA 94305, USA. ; Department of Mathematics and Statistics, Swarthmore College, Swarthmore, PA 19081, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25700517" target="_blank"〉PubMed〈/a〉

    Description: Innate lymphoid cells (ILCs) are a growing family of immune cells that mirror the phenotypes and functions of T cells. However, in contrast to T cells, ILCs do not express acquired antigen receptors or undergo clonal selection and expansion when stimulated. Instead, ILCs react promptly to signals from infected or injured tissues and produce an array of secreted proteins termed cytokines that direct the developing immune response into one that is adapted to the original insult. The complex cross-talk between microenvironment, ILCs, and adaptive immunity remains to be fully deciphered. Only by understanding these complex regulatory networks can the power of ILCs be controlled or unleashed in order to regulate or enhance immune responses in disease prevention and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eberl, Gerard -- Colonna, Marco -- Di Santo, James P -- McKenzie, Andrew N J -- 100963/Wellcome Trust/United Kingdom -- 1U01AI095542/AI/NIAID NIH HHS/ -- MC_U105178805/Medical Research Council/United Kingdom -- R01DE021255/DE/NIDCR NIH HHS/ -- R21CA16719/CA/NCI NIH HHS/ -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 May 22;348(6237):aaa6566. doi: 10.1126/science.aaa6566.

    Description: Research in the genetics of neurodevelopmental disorders such as autism suggests that several hundred genes are likely risk factors for these disorders. This heterogeneity presents a challenge and an opportunity at the same time. Although the exact identity of many of the genes remains to be discovered, genes identified to date encode proteins that play roles in certain conserved pathways: protein synthesis, transcriptional and epigenetic regulation, and synaptic signaling. The next generation of research in neurodevelopmental disorders must address the neural circuitry underlying the behavioral symptoms and comorbidities, the cell types playing critical roles in these circuits, and common intercellular signaling pathways that link diverse genes. Results from clinical trials have been mixed so far. Only when we can leverage the heterogeneity of neurodevelopmental disorders into precision medicine will the mechanism-based therapeutics for these disorders start to unlock success.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4739545/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4739545/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sahin, Mustafa -- Sur, Mriganka -- EF1451125/PHS HHS/ -- EY007023/EY/NEI NIH HHS/ -- MH085802/MH/NIMH NIH HHS/ -- NS090473/NS/NINDS NIH HHS/ -- P20 NS080199/NS/NINDS NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- U01 NS082320/NS/NINDS NIH HHS/ -- U54 NS092090/NS/NINDS NIH HHS/ -- U54NS092090/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2015 Nov 20;350(6263). pii: aab3897. doi: 10.1126/science.aab3897.

    Description: Cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) detects intracellular DNA and signals through the adapter protein STING to initiate the antiviral response to DNA viruses. Whether DNA viruses can prevent activation of the cGAS-STING pathway remains largely unknown. Here, we identify the oncogenes of the DNA tumor viruses, including E7 from human papillomavirus (HPV) and E1A from adenovirus, as potent and specific inhibitors of the cGAS-STING pathway. We show that the LXCXE motif of these oncoproteins, which is essential for blockade of the retinoblastoma tumor suppressor, is also important for antagonizing DNA sensing. E1A and E7 bind to STING, and silencing of these oncogenes in human tumor cells restores the cGAS-STING pathway. Our findings reveal a host-virus conflict that may have shaped the evolution of viral oncogenes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lau, Laura -- Gray, Elizabeth E -- Brunette, Rebecca L -- Stetson, Daniel B -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):568-71. doi: 10.1126/science.aab3291.

    Description: Following the end-Devonian mass extinction (359 million years ago), vertebrates experienced persistent reductions in body size for at least 36 million years. Global shrinkage was not related to oxygen or temperature, which suggests that ecological drivers played a key role in determining the length and direction of size trends. Small, fast-breeding ray-finned fishes, sharks, and tetrapods, most under 1 meter in length from snout to tail, radiated to dominate postextinction ecosystems and vertebrae biodiversity. The few large-bodied, slow-breeding survivors failed to diversify, facing extinction despite earlier evolutionary success. Thus, the recovery interval resembled modern ecological successions in terms of active selection on size and related life histories. Disruption of global vertebrate, and particularly fish, biotas may commonly lead to widespread, long-term reduction in body size, structuring future biodiversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sallan, Lauren -- Galimberti, Andrew K -- New York, N.Y. -- Science. 2015 Nov 13;350(6262):812-5. doi: 10.1126/science.aac7373.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Environmental Science, University of Pennsylvania, Philadelphia, PA 19104, USA. lsallan@sas.upenn.edu. ; Department of Biology, Kalamazoo College, Kalamazoo, MI 49006, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26564854" target="_blank"〉PubMed〈/a〉

    Description: Podophyllotoxin is the natural product precursor of the chemotherapeutic etoposide, yet only part of its biosynthetic pathway is known. We used transcriptome mining in Podophyllum hexandrum (mayapple) to identify biosynthetic genes in the podophyllotoxin pathway. We selected 29 candidate genes to combinatorially express in Nicotiana benthamiana (tobacco) and identified six pathway enzymes, including an oxoglutarate-dependent dioxygenase that closes the core cyclohexane ring of the aryltetralin scaffold. By coexpressing 10 genes in tobacco-these 6 plus 4 previously discovered-we reconstitute the pathway to (-)-4'-desmethylepipodophyllotoxin (the etoposide aglycone), a naturally occurring lignan that is the immediate precursor of etoposide and, unlike podophyllotoxin, a potent topoisomerase inhibitor. Our results enable production of the etoposide aglycone in tobacco and circumvent the need for cultivation of mayapple and semisynthetic epimerization and demethylation of podophyllotoxin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lau, Warren -- Sattely, Elizabeth S -- DP2 AT008321/AT/NCCIH NIH HHS/ -- R00 GM089985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Sep 11;349(6253):1224-8. doi: 10.1126/science.aac7202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Stanford University, Stanford, CA 94305, USA. ; Department of Chemical Engineering, Stanford University, Stanford, CA 94305, USA. sattely@stanford.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26359402" target="_blank"〉PubMed〈/a〉

    Description: Human-like modes of communication, including mutual gaze, in dogs may have been acquired during domestication with humans. We show that gazing behavior from dogs, but not wolves, increased urinary oxytocin concentrations in owners, which consequently facilitated owners' affiliation and increased oxytocin concentration in dogs. Further, nasally administered oxytocin increased gazing behavior in dogs, which in turn increased urinary oxytocin concentrations in owners. These findings support the existence of an interspecies oxytocin-mediated positive loop facilitated and modulated by gazing, which may have supported the coevolution of human-dog bonding by engaging common modes of communicating social attachment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nagasawa, Miho -- Mitsui, Shouhei -- En, Shiori -- Ohtani, Nobuyo -- Ohta, Mitsuaki -- Sakuma, Yasuo -- Onaka, Tatsushi -- Mogi, Kazutaka -- Kikusui, Takefumi -- New York, N.Y. -- Science. 2015 Apr 17;348(6232):333-6. doi: 10.1126/science.1261022.

    Description: Monoclonal antibodies directed against cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), such as ipilimumab, yield considerable clinical benefit for patients with metastatic melanoma by inhibiting immune checkpoint activity, but clinical predictors of response to these therapies remain incompletely characterized. To investigate the roles of tumor-specific neoantigens and alterations in the tumor microenvironment in the response to ipilimumab, we analyzed whole exomes from pretreatment melanoma tumor biopsies and matching germline tissue samples from 110 patients. For 40 of these patients, we also obtained and analyzed transcriptome data from the pretreatment tumor samples. Overall mutational load, neoantigen load, and expression of cytolytic markers in the immune microenvironment were significantly associated with clinical benefit. However, no recurrent neoantigen peptide sequences predicted responder patient populations. Thus, detailed integrated molecular characterization of large patient cohorts may be needed to identify robust determinants of response and resistance to immune checkpoint inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Shukla, Sachet A -- Blank, Christian -- Zimmer, Lisa -- Sucker, Antje -- Hillen, Uwe -- Foppen, Marnix H Geukes -- Goldinger, Simone M -- Utikal, Jochen -- Hassel, Jessica C -- Weide, Benjamin -- Kaehler, Katharina C -- Loquai, Carmen -- Mohr, Peter -- Gutzmer, Ralf -- Dummer, Reinhard -- Gabriel, Stacey -- Wu, Catherine J -- Schadendorf, Dirk -- Garraway, Levi A -- U54 HG003067/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):207-11. doi: 10.1126/science.aad0095.

    Description: DNA strand exchange plays a central role in genetic recombination across all kingdoms of life, but the physical basis for these reactions remains poorly defined. Using single-molecule imaging, we found that bacterial RecA and eukaryotic Rad51 and Dmc1 all stabilize strand exchange intermediates in precise three-nucleotide steps. Each step coincides with an energetic signature (0.3 kBT) that is conserved from bacteria to humans. Triplet recognition is strictly dependent on correct Watson-Crick pairing. Rad51, RecA, and Dmc1 can all step over mismatches, but only Dmc1 can stabilize mismatched triplets. This finding provides insight into why eukaryotes have evolved a meiosis-specific recombinase. We propose that canonical Watson-Crick base triplets serve as the fundamental unit of pairing interactions during DNA recombination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4580133/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4580133/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Ja Yil -- Terakawa, Tsuyoshi -- Qi, Zhi -- Steinfeld, Justin B -- Redding, Sy -- Kwon, YoungHo -- Gaines, William A -- Zhao, Weixing -- Sung, Patrick -- Greene, Eric C -- CA146940/CA/NCI NIH HHS/ -- GM074739/GM/NIGMS NIH HHS/ -- R01 CA146940/CA/NCI NIH HHS/ -- R01 ES015252/ES/NIEHS NIH HHS/ -- R01 GM074739/GM/NIGMS NIH HHS/ -- R01ES015252/ES/NIEHS NIH HHS/ -- T32 GM007367/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Aug 28;349(6251):977-81. doi: 10.1126/science.aab2666.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biophysics, Columbia University, New York, NY, USA. ; Department of Biochemistry and Molecular Biophysics, Columbia University, New York, NY, USA.

This implicates missense mutations as a source of patient-specific neoantigens. However, a systematic evaluation of these putative neoantigens as targets of antitumor immunity is lacking. Moreover, it remains unknown whether vaccination can augment such responses. We found that a dendritic cell vaccine led to an increase in naturally occurring neoantigen-specific immunity and revealed previously undetected human leukocyte antigen (HLA) class I-restricted neoantigens in patients with advanced melanoma. The presentation of neoantigens by HLA-A*02:01 in human melanoma was confirmed by mass spectrometry. Vaccination promoted a diverse neoantigen-specific T cell receptor (TCR) repertoire in terms of both TCR-beta usage and clonal composition. Our results demonstrate that vaccination directed at tumor-encoded amino acid substitutions broadens the antigenic breadth and clonal diversity of antitumor immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4549796/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4549796/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carreno, Beatriz M -- Magrini, Vincent -- Becker-Hapak, Michelle -- Kaabinejadian, Saghar -- Hundal, Jasreet -- Petti, Allegra A -- Ly, Amy -- Lie, Wen-Rong -- Hildebrand, William H -- Mardis, Elaine R -- Linette, Gerald P -- 5U54HG00307/HG/NHGRI NIH HHS/ -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA91842/CA/NCI NIH HHS/ -- R21 CA179695/CA/NCI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 May 15;348(6236):803-8. doi: 10.1126/science.aaa3828.

    Description: The clinical relevance of T cells in the control of a diverse set of human cancers is now beyond doubt. However, the nature of the antigens that allow the immune system to distinguish cancer cells from noncancer cells has long remained obscure. Recent technological innovations have made it possible to dissect the immune response to patient-specific neoantigens that arise as a consequence of tumor-specific mutations, and emerging data suggest that recognition of such neoantigens is a major factor in the activity of clinical immunotherapies. These observations indicate that neoantigen load may form a biomarker in cancer immunotherapy and provide an incentive for the development of novel therapeutic approaches that selectively enhance T cell reactivity against this class of antigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schumacher, Ton N -- Schreiber, Robert D -- R01CA04305926/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):69-74. doi: 10.1126/science.aaa4971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Immunology, Netherlands Cancer Institute, Plesmanlaan 121, 1066 CX, Amsterdam, Netherlands. t.schumacher@nki.nl schreiber@immunology.wustl.edu. ; Department of Pathology and Immunology, Washington University School of Medicine, 660 South Euclid Avenue, St. Louis, MO 63110, USA. t.schumacher@nki.nl schreiber@immunology.wustl.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25838375" target="_blank"〉PubMed〈/a〉

    Description: NADPH/NADP(+) (the reduced form of NADP(+)/nicotinamide adenine dinucleotide phosphate) homeostasis is critical for countering oxidative stress in cells. Nicotinamide nucleotide transhydrogenase (TH), a membrane enzyme present in both bacteria and mitochondria, couples the proton motive force to the generation of NADPH. We present the 2.8 A crystal structure of the transmembrane proton channel domain of TH from Thermus thermophilus and the 6.9 A crystal structure of the entire enzyme (holo-TH). The membrane domain crystallized as a symmetric dimer, with each protomer containing a putative proton channel. The holo-TH is a highly asymmetric dimer with the NADP(H)-binding domain (dIII) in two different orientations. This unusual arrangement suggests a catalytic mechanism in which the two copies of dIII alternatively function in proton translocation and hydride transfer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4479213/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4479213/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, Josephine H -- Schurig-Briccio, Lici A -- Yamaguchi, Mutsuo -- Moeller, Arne -- Speir, Jeffrey A -- Gennis, Robert B -- Stout, Charles D -- 1R01GM103838-01A1/GM/NIGMS NIH HHS/ -- 5R01GM061545/GM/NIGMS NIH HHS/ -- GM073197/GM/NIGMS NIH HHS/ -- GM095600/GM/NIGMS NIH HHS/ -- P41 GM103310/GM/NIGMS NIH HHS/ -- P41GM103310/GM/NIGMS NIH HHS/ -- R01 GM061545/GM/NIGMS NIH HHS/ -- R01 GM095600/GM/NIGMS NIH HHS/ -- R01 GM103838/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Jan 9;347(6218):178-81. doi: 10.1126/science.1260451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Structural and Computational Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. ; Department of Biochemistry, University of Illinois, Urbana, IL 61801, USA. ; National Resource for Automated Molecular Microscopy, The Scripps Research Institute, La Jolla, CA 92037, USA. ; Department of Integrative Structural and Computational Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. dave@scripps.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25574024" target="_blank"〉PubMed〈/a〉

    Description: Hawks et al. argue that our analysis of Australopithecus sediba mandibles is flawed and that specimen LD 350-1 cannot be distinguished from this, or any other, Australopithecus species. Our reexamination of the evidence confirms that LD 350-1 falls outside of the pattern that A. sediba shares with Australopithecus and thus is reasonably assigned to the genus Homo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Villmoare, Brian -- Kimbel, William H -- Seyoum, Chalachew -- Campisano, Christopher J -- DiMaggio, Erin -- Rowan, John -- Braun, David R -- Arrowsmith, J Ramon -- Reed, Kaye E -- New York, N.Y. -- Science. 2015 Jun 19;348(6241):1326. doi: 10.1126/science.aab1122.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Nevada Las Vegas, Las Vegas, NV, 89154, USA.

    Description: Base-pairing interactions between nucleic acids mediate target recognition in many biological processes. We developed a super-resolution imaging and modeling platform that enabled the in vivo determination of base pairing-mediated target recognition kinetics. We examined a stress-induced bacterial small RNA, SgrS, which induces the degradation of target messenger RNAs (mRNAs). SgrS binds to a primary target mRNA in a reversible and dynamic fashion, and formation of SgrS-mRNA complexes is rate-limiting, dictating the overall regulation efficiency in vivo. Examination of a secondary target indicated that differences in the target search kinetics contribute to setting the regulation priority among different target mRNAs. This super-resolution imaging and analysis approach provides a conceptual framework that can be generalized to other small RNA systems and other target search processes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4410144/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4410144/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fei, Jingyi -- Singh, Digvijay -- Zhang, Qiucen -- Park, Seongjin -- Balasubramanian, Divya -- Golding, Ido -- Vanderpool, Carin K -- Ha, Taekjip -- GM 112659/GM/NIGMS NIH HHS/ -- GM065367/GM/NIGMS NIH HHS/ -- GM082837/GM/NIGMS NIH HHS/ -- GM092830/GM/NIGMS NIH HHS/ -- R01 GM065367/GM/NIGMS NIH HHS/ -- R01 GM082837/GM/NIGMS NIH HHS/ -- R01 GM092830/GM/NIGMS NIH HHS/ -- R01 GM112659/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 20;347(6228):1371-4. doi: 10.1126/science.1258849.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for the Physics of Living Cells, Department of Physics, University of Illinois, Urbana, IL, USA. ; Center for Biophysics and Computational Biology, University of Illinois, Urbana, IL, USA. ; Department of Microbiology, University of Illinois, Urbana, IL, USA. ; Center for the Physics of Living Cells, Department of Physics, University of Illinois, Urbana, IL, USA.

    Description: Our understanding of the origin of the genus Homo has been hampered by a limited fossil record in eastern Africa between 2.0 and 3.0 million years ago (Ma). Here we report the discovery of a partial hominin mandible with teeth from the Ledi-Geraru research area, Afar Regional State, Ethiopia, that establishes the presence of Homo at 2.80 to 2.75 Ma. This specimen combines primitive traits seen in early Australopithecus with derived morphology observed in later Homo, confirming that dentognathic departures from the australopith pattern occurred early in the Homo lineage. The Ledi-Geraru discovery has implications for hypotheses about the timing and place of origin of the genus Homo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Villmoare, Brian -- Kimbel, William H -- Seyoum, Chalachew -- Campisano, Christopher J -- DiMaggio, Erin N -- Rowan, John -- Braun, David R -- Arrowsmith, J Ramon -- Reed, Kaye E -- New York, N.Y. -- Science. 2015 Mar 20;347(6228):1352-5. doi: 10.1126/science.aaa1343.

    Description: The 18-kilodalton translocator protein (TSPO), proposed to be a key player in cholesterol transport into mitochondria, is highly expressed in steroidogenic tissues, metastatic cancer, and inflammatory and neurological diseases such as Alzheimer's and Parkinson's. TSPO ligands, including benzodiazepine drugs, are implicated in regulating apoptosis and are extensively used in diagnostic imaging. We report crystal structures (at 1.8, 2.4, and 2.5 angstrom resolution) of TSPO from Rhodobacter sphaeroides and a mutant that mimics the human Ala(147)--〉Thr(147) polymorphism associated with psychiatric disorders and reduced pregnenolone production. Crystals obtained in the lipidic cubic phase reveal the binding site of an endogenous porphyrin ligand and conformational effects of the mutation. The three crystal structures show the same tightly interacting dimer and provide insights into the controversial physiological role of TSPO and how the mutation affects cholesterol binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Fei -- Liu, Jian -- Zheng, Yi -- Garavito, R Michael -- Ferguson-Miller, Shelagh -- ACB-12002/PHS HHS/ -- AGM-12006/PHS HHS/ -- GM094625/GM/NIGMS NIH HHS/ -- GM26916/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Jan 30;347(6221):555-8. doi: 10.1126/science.1260590.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, MI 48824, USA. ; Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, MI 48824, USA. fergus20@msu.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25635101" target="_blank"〉PubMed〈/a〉

    Description: Adenosine-to-inosine (A-to-I) editing is a highly prevalent posttranscriptional modification of RNA, mediated by ADAR (adenosine deaminase acting on RNA) enzymes. In addition to RNA editing, additional functions have been proposed for ADAR1. To determine the specific role of RNA editing by ADAR1, we generated mice with an editing-deficient knock-in mutation (Adar1(E861A), where E861A denotes Glu(861)--〉Ala(861)). Adar1(E861A/E861A) embryos died at ~E13.5 (embryonic day 13.5), with activated interferon and double-stranded RNA (dsRNA)-sensing pathways. Genome-wide analysis of the in vivo substrates of ADAR1 identified clustered hyperediting within long dsRNA stem loops within 3' untranslated regions of endogenous transcripts. Finally, embryonic death and phenotypes of Adar1(E861A/E861A) were rescued by concurrent deletion of the cytosolic sensor of dsRNA, MDA5. A-to-I editing of endogenous dsRNA is the essential function of ADAR1, preventing the activation of the cytosolic dsRNA response by endogenous transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liddicoat, Brian J -- Piskol, Robert -- Chalk, Alistair M -- Ramaswami, Gokul -- Higuchi, Miyoko -- Hartner, Jochen C -- Li, Jin Billy -- Seeburg, Peter H -- Walkley, Carl R -- R01GM102484/GM/NIGMS NIH HHS/ -- T32 HG000044/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 Sep 4;349(6252):1115-20. doi: 10.1126/science.aac7049.

    Description: Retroviruses depend on self-assembly of their capsid proteins (core particle) to yield infectious mature virions. Despite the essential role of the retroviral core, its high polymorphism has hindered high-resolution structural analyses. Here, we report the x-ray structure of the native capsid (CA) protein from bovine leukemia virus. CA is organized as hexamers that deviate substantially from sixfold symmetry, yet adjust to make two-dimensional pseudohexagonal arrays that mimic mature retroviral cores. Intra- and interhexameric quasi-equivalent contacts are uncovered, with flexible trimeric lateral contacts among hexamers, yet preserving very similar dimeric interfaces making the lattice. The conformation of each capsid subunit in the hexamer is therefore dictated by long-range interactions, revealing how the hexamers can also assemble into closed core particles, a relevant feature of retrovirus biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Obal, G -- Trajtenberg, F -- Carrion, F -- Tome, L -- Larrieux, N -- Zhang, X -- Pritsch, O -- Buschiazzo, A -- New York, N.Y. -- Science. 2015 Jul 3;349(6243):95-8. doi: 10.1126/science.aaa5182.

    Description: Human inborn errors of immunity mediated by the cytokines interleukin-17A and interleukin-17F (IL-17A/F) underlie mucocutaneous candidiasis, whereas inborn errors of interferon-gamma (IFN-gamma) immunity underlie mycobacterial disease. We report the discovery of bi-allelic RORC loss-of-function mutations in seven individuals from three kindreds of different ethnic origins with both candidiasis and mycobacteriosis. The lack of functional RORgamma and RORgammaT isoforms resulted in the absence of IL-17A/F-producing T cells in these individuals, probably accounting for their chronic candidiasis. Unexpectedly, leukocytes from RORgamma- and RORgammaT-deficient individuals also displayed an impaired IFN-gamma response to Mycobacterium. This principally reflected profoundly defective IFN-gamma production by circulating gammadelta T cells and CD4(+)CCR6(+)CXCR3(+) alphabeta T cells. In humans, both mucocutaneous immunity to Candida and systemic immunity to Mycobacterium require RORgamma, RORgammaT, or both.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4668938/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4668938/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okada, Satoshi -- Markle, Janet G -- Deenick, Elissa K -- Mele, Federico -- Averbuch, Dina -- Lagos, Macarena -- Alzahrani, Mohammed -- Al-Muhsen, Saleh -- Halwani, Rabih -- Ma, Cindy S -- Wong, Natalie -- Soudais, Claire -- Henderson, Lauren A -- Marzouqa, Hiyam -- Shamma, Jamal -- Gonzalez, Marcela -- Martinez-Barricarte, Ruben -- Okada, Chizuru -- Avery, Danielle T -- Latorre, Daniela -- Deswarte, Caroline -- Jabot-Hanin, Fabienne -- Torrado, Egidio -- Fountain, Jeffrey -- Belkadi, Aziz -- Itan, Yuval -- Boisson, Bertrand -- Migaud, Melanie -- Arlehamn, Cecilia S Lindestam -- Sette, Alessandro -- Breton, Sylvain -- McCluskey, James -- Rossjohn, Jamie -- de Villartay, Jean-Pierre -- Moshous, Despina -- Hambleton, Sophie -- Latour, Sylvain -- Arkwright, Peter D -- Picard, Capucine -- Lantz, Olivier -- Engelhard, Dan -- Kobayashi, Masao -- Abel, Laurent -- Cooper, Andrea M -- Notarangelo, Luigi D -- Boisson-Dupuis, Stephanie -- Puel, Anne -- Sallusto, Federica -- Bustamante, Jacinta -- Tangye, Stuart G -- Casanova, Jean-Laurent -- 8UL1TR000043/TR/NCATS NIH HHS/ -- HHSN272200900044C/AI/NIAID NIH HHS/ -- HHSN272200900044C/PHS HHS/ -- R37 AI095983/AI/NIAID NIH HHS/ -- R37AI095983/AI/NIAID NIH HHS/ -- T32 AI007512/AI/NIAID NIH HHS/ -- Canadian Institutes of Health Research/Canada -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Aug 7;349(6248):606-13. doi: 10.1126/science.aaa4282.

    Description: Mammoths provide a detailed example of species origins and dispersal, but understanding has been impeded by taxonomic confusion, especially in North America. The Columbian mammoth Mammuthus columbi was thought to have evolved in North America from a more primitive Eurasian immigrant. The earliest American mammoths (1.5 million years ago), however, resemble the advanced Eurasian M. trogontherii that crossed the Bering land bridge around that time, giving rise directly to M. columbi. Woolly mammoth M. primigenius later evolved in Beringia and spread into Europe and North America, leading to a diversity of morphologies as it encountered endemic M. trogontherii and M. columbi, respectively. In North America, this included intermediates ("M. jeffersonii"), suggesting introgression of M. primigenius with M. columbi. The lineage illustrates the dynamic interplay of local adaptation, dispersal, and gene flow in the evolution of a widely distributed species complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, A M -- Sher, A V -- New York, N.Y. -- Science. 2015 Nov 13;350(6262):805-9. doi: 10.1126/science.aac5660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Natural History Museum, London SW7 5BD, UK. a.lister@nhm.ac.uk. ; Severtsov Institute of Ecology and Evolution, Moscow 119071, Russia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26564853" target="_blank"〉PubMed〈/a〉

    Description: Double-stranded RNA (dsRNA) viruses possess a segmented dsRNA genome and a number of RNA-dependent RNA polymerases (RdRps) enclosed in a capsid. Until now, the precise structures of genomes and RdRps within the capsids have been unknown. Here we report the structures of RdRps and associated RNAs within nontranscribing and transcribing cypoviruses (NCPV and TCPV, respectively), using a combination of cryo-electron microscopy (cryo-EM) and a symmetry-mismatch reconstruction method. The RdRps and associated RNAs appear to exhibit a pseudo-D3 symmetric organization in both NCPV and TCPV. However, the molecular interactions between RdRps and the genomic RNA were found to differ in these states. Our work provides insight into the mechanisms of the replication and transcription in dsRNA viruses and paves a way for structural determination of lower-symmetry complexes enclosed in higher-symmetry structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Hongrong -- Cheng, Lingpeng -- New York, N.Y. -- Science. 2015 Sep 18;349(6254):1347-50. doi: 10.1126/science.aaa4938.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉College of Physics and Information Science, Hunan Normal University, Changsha, Hunan 410081, China. hrliu@hunnu.edu.cn lingpengcheng@mail.tsinghua.edu.cn. ; School of Life Sciences, Tsinghua University, Beijing 100084, China. hrliu@hunnu.edu.cn lingpengcheng@mail.tsinghua.edu.cn.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26383954" target="_blank"〉PubMed〈/a〉

    Description: Cardiac progenitor cells are multipotent and give rise to cardiac endothelium, smooth muscle, and cardiomyocytes. Here, we define and characterize the cardiomyoblast intermediate that is committed to the cardiomyocyte fate, and we characterize the niche signals that regulate commitment. Cardiomyoblasts express Hopx, which functions to coordinate local Bmp signals to inhibit the Wnt pathway, thus promoting cardiomyogenesis. Hopx integrates Bmp and Wnt signaling by physically interacting with activated Smads and repressing Wnt genes. The identification of the committed cardiomyoblast that retains proliferative potential will inform cardiac regenerative therapeutics. In addition, Bmp signals characterize adult stem cell niches in other tissues where Hopx-mediated inhibition of Wnt is likely to contribute to stem cell quiescence and to explain the role of Hopx as a tumor suppressor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jain, Rajan -- Li, Deqiang -- Gupta, Mudit -- Manderfield, Lauren J -- Ifkovits, Jamie L -- Wang, Qiaohong -- Liu, Feiyan -- Liu, Ying -- Poleshko, Andrey -- Padmanabhan, Arun -- Raum, Jeffrey C -- Li, Li -- Morrisey, Edward E -- Lu, Min Min -- Won, Kyoung-Jae -- Epstein, Jonathan A -- 5-T32-GM-007170/GM/NIGMS NIH HHS/ -- K08 HL119553/HL/NHLBI NIH HHS/ -- K08 HL119553-02/HL/NHLBI NIH HHS/ -- R01 HL071546/HL/NHLBI NIH HHS/ -- U01 HL100405/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2015 Jun 26;348(6242):aaa6071. doi: 10.1126/science.aaa6071.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell and Developmental Biology, Penn Cardiovascular Institute, Institute of Regenerative Medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA 19104, USA. ; Department of Genetics, Institute for Diabetes, Obesity, and Metabolism, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA 19104, USA. ; Department of Cell and Developmental Biology, Penn Cardiovascular Institute, Institute of Regenerative Medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA 19104, USA. epsteinj@upenn.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26113728" target="_blank"〉PubMed〈/a〉

    Description: The mechanistic target of rapamycin complex 1 (mTORC1) protein kinase is a master growth regulator that responds to multiple environmental cues. Amino acids stimulate, in a Rag-, Ragulator-, and vacuolar adenosine triphosphatase-dependent fashion, the translocation of mTORC1 to the lysosomal surface, where it interacts with its activator Rheb. Here, we identify SLC38A9, an uncharacterized protein with sequence similarity to amino acid transporters, as a lysosomal transmembrane protein that interacts with the Rag guanosine triphosphatases (GTPases) and Ragulator in an amino acid-sensitive fashion. SLC38A9 transports arginine with a high Michaelis constant, and loss of SLC38A9 represses mTORC1 activation by amino acids, particularly arginine. Overexpression of SLC38A9 or just its Ragulator-binding domain makes mTORC1 signaling insensitive to amino acid starvation but not to Rag activity. Thus, SLC38A9 functions upstream of the Rag GTPases and is an excellent candidate for being an arginine sensor for the mTORC1 pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295826/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295826/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Shuyu -- Tsun, Zhi-Yang -- Wolfson, Rachel L -- Shen, Kuang -- Wyant, Gregory A -- Plovanich, Molly E -- Yuan, Elizabeth D -- Jones, Tony D -- Chantranupong, Lynne -- Comb, William -- Wang, Tim -- Bar-Peled, Liron -- Zoncu, Roberto -- Straub, Christoph -- Kim, Choah -- Park, Jiwon -- Sabatini, Bernardo L -- Sabatini, David M -- AI47389/AI/NIAID NIH HHS/ -- F30 CA180754/CA/NCI NIH HHS/ -- F31 AG044064/AG/NIA NIH HHS/ -- F31 CA180271/CA/NCI NIH HHS/ -- R01 CA103866/CA/NCI NIH HHS/ -- R37 AI047389/AI/NIAID NIH HHS/ -- T32 GM007287/GM/NIGMS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jan 9;347(6218):188-94. doi: 10.1126/science.1257132.

    Description: During virus infection, the adaptor proteins MAVS and STING transduce signals from the cytosolic nucleic acid sensors RIG-I and cGAS, respectively, to induce type I interferons (IFNs) and other antiviral molecules. Here we show that MAVS and STING harbor two conserved serine and threonine clusters that are phosphorylated by the kinases IKK and/or TBK1 in response to stimulation. Phosphorylated MAVS and STING then bind to a positively charged surface of interferon regulatory factor 3 (IRF3) and thereby recruit IRF3 for its phosphorylation and activation by TBK1. We further show that TRIF, an adaptor protein in Toll-like receptor signaling, activates IRF3 through a similar phosphorylation-dependent mechanism. These results reveal that phosphorylation of innate adaptor proteins is an essential and conserved mechanism that selectively recruits IRF3 to activate the type I IFN pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Siqi -- Cai, Xin -- Wu, Jiaxi -- Cong, Qian -- Chen, Xiang -- Li, Tuo -- Du, Fenghe -- Ren, Junyao -- Wu, You-Tong -- Grishin, Nick V -- Chen, Zhijian J -- AI-93967/AI/NIAID NIH HHS/ -- GM-094575/GM/NIGMS NIH HHS/ -- GM-63692/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):aaa2630. doi: 10.1126/science.aaa2630.

    Description: An organism with a single recessive loss-of-function allele will typically have a wild-type phenotype, whereas individuals homozygous for two copies of the allele will display a mutant phenotype. We have developed a method called the mutagenic chain reaction (MCR), which is based on the CRISPR/Cas9 genome-editing system for generating autocatalytic mutations, to produce homozygous loss-of-function mutations. In Drosophila, we found that MCR mutations efficiently spread from their chromosome of origin to the homologous chromosome, thereby converting heterozygous mutations to homozygosity in the vast majority of somatic and germline cells. MCR technology should have broad applications in diverse organisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687737/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687737/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gantz, Valentino M -- Bier, Ethan -- R01 AI070654/AI/NIAID NIH HHS/ -- R01 AI110713/AI/NIAID NIH HHS/ -- R01 GM067247/GM/NIGMS NIH HHS/ -- R56 NS029870/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 24;348(6233):442-4. doi: 10.1126/science.aaa5945.

    Description: In Eukarya, stalled translation induces 40S dissociation and recruitment of the ribosome quality control complex (RQC) to the 60S subunit, which mediates nascent chain degradation. Here we report cryo-electron microscopy structures revealing that the RQC components Rqc2p (YPL009C/Tae2) and Ltn1p (YMR247C/Rkr1) bind to the 60S subunit at sites exposed after 40S dissociation, placing the Ltn1p RING (Really Interesting New Gene) domain near the exit channel and Rqc2p over the P-site transfer RNA (tRNA). We further demonstrate that Rqc2p recruits alanine- and threonine-charged tRNA to the A site and directs the elongation of nascent chains independently of mRNA or 40S subunits. Our work uncovers an unexpected mechanism of protein synthesis, in which a protein--not an mRNA--determines tRNA recruitment and the tagging of nascent chains with carboxy-terminal Ala and Thr extensions ("CAT tails").〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451101/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451101/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Peter S -- Park, Joseph -- Qin, Yidan -- Li, Xueming -- Parsawar, Krishna -- Larson, Matthew H -- Cox, James -- Cheng, Yifan -- Lambowitz, Alan M -- Weissman, Jonathan S -- Brandman, Onn -- Frost, Adam -- 1DP2GM110772-01/DP/NCCDPHP CDC HHS/ -- DP2 GM110772/GM/NIGMS NIH HHS/ -- GM37949/GM/NIGMS NIH HHS/ -- GM37951/GM/NIGMS NIH HHS/ -- P50 GM102706/GM/NIGMS NIH HHS/ -- R01 GM037949/GM/NIGMS NIH HHS/ -- R01 GM037951/GM/NIGMS NIH HHS/ -- U01 GM098254/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jan 2;347(6217):75-8. doi: 10.1126/science.1259724.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utah, UT 84112, USA. ; Department of Biochemistry, Stanford University, Palo Alto, CA 94305, USA. ; Institute for Cellular and Molecular Biology, University of Texas at Austin, Austin, TX 78712, USA.

    Description: Voltage-gated sodium (Nav) channels propagate action potentials in excitable cells. Accordingly, Nav channels are therapeutic targets for many cardiovascular and neurological disorders. Selective inhibitors have been challenging to design because the nine mammalian Nav channel isoforms share high sequence identity and remain recalcitrant to high-resolution structural studies. Targeting the human Nav1.7 channel involved in pain perception, we present a protein-engineering strategy that has allowed us to determine crystal structures of a novel receptor site in complex with isoform-selective antagonists. GX-936 and related inhibitors bind to the activated state of voltage-sensor domain IV (VSD4), where their anionic aryl sulfonamide warhead engages the fourth arginine gating charge on the S4 helix. By opposing VSD4 deactivation, these compounds inhibit Nav1.7 through a voltage-sensor trapping mechanism, likely by stabilizing inactivated states of the channel. Residues from the S2 and S3 helices are key determinants of isoform selectivity, and bound phospholipids implicate the membrane as a modulator of channel function and pharmacology. Our results help to elucidate the molecular basis of voltage sensing and establish structural blueprints to design selective Nav channel antagonists.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahuja, Shivani -- Mukund, Susmith -- Deng, Lunbin -- Khakh, Kuldip -- Chang, Elaine -- Ho, Hoangdung -- Shriver, Stephanie -- Young, Clint -- Lin, Sophia -- Johnson, J P Jr -- Wu, Ping -- Li, Jun -- Coons, Mary -- Tam, Christine -- Brillantes, Bobby -- Sampang, Honorio -- Mortara, Kyle -- Bowman, Krista K -- Clark, Kevin R -- Estevez, Alberto -- Xie, Zhiwei -- Verschoof, Henry -- Grimwood, Michael -- Dehnhardt, Christoph -- Andrez, Jean-Christophe -- Focken, Thilo -- Sutherlin, Daniel P -- Safina, Brian S -- Starovasnik, Melissa A -- Ortwine, Daniel F -- Franke, Yvonne -- Cohen, Charles J -- Hackos, David H -- Koth, Christopher M -- Payandeh, Jian -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):aac5464. doi: 10.1126/science.aac5464.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Neuroscience, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Biology, Xenon Pharmaceuticals Inc., Burnaby, British Columbia, V5G 4W8, Canada. ; Department of Discovery Chemistry, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Biochemical and Cellular Pharmacology, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Chemistry, Xenon Pharmaceuticals Inc., Burnaby, British Columbia, V5G 4W8, Canada. ; Department of Neuroscience, Genentech Inc., South San Francisco, CA 94080, USA. hackos.david@gene.com koth.christopher@gene.com payandeh.jian@gene.com. ; Department of Structural Biology, Genentech Inc., South San Francisco, CA 94080, USA. hackos.david@gene.com koth.christopher@gene.com payandeh.jian@gene.com.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26680203" target="_blank"〉PubMed〈/a〉

    Description: The spindle checkpoint of the cell division cycle senses kinetochores that are not attached to microtubules and prevents precocious onset of anaphase, which can lead to aneuploidy. The nuclear division cycle 80 complex (Ndc80C) is a major microtubule receptor at the kinetochore. Ndc80C also mediates the kinetochore recruitment of checkpoint proteins. We found that the checkpoint protein kinase monopolar spindle 1 (Mps1) directly bound to Ndc80C through two independent interactions. Both interactions involved the microtubule-binding surfaces of Ndc80C and were directly inhibited in the presence of microtubules. Elimination of one such interaction in human cells caused checkpoint defects expected from a failure to detect unattached kinetochores. Competition between Mps1 and microtubules for Ndc80C binding thus constitutes a direct mechanism for the detection of unattached kinetochores.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ji, Zhejian -- Gao, Haishan -- Yu, Hongtao -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jun 12;348(6240):1260-4. doi: 10.1126/science.aaa4029.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Pharmacology, University of Texas Southwestern Medical Center, 6001 Forest Park Road, Dallas, TX 74390, USA. ; Howard Hughes Medical Institute, Department of Pharmacology, University of Texas Southwestern Medical Center, 6001 Forest Park Road, Dallas, TX 74390, USA. hongtao.yu@utsouthwestern.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26068854" target="_blank"〉PubMed〈/a〉

    Description: Lipid transfer between cell membrane bilayers at contacts between the endoplasmic reticulum (ER) and other membranes help to maintain membrane lipid homeostasis. We found that two similar ER integral membrane proteins, oxysterol-binding protein (OSBP)-related protein 5 (ORP5) and ORP8, tethered the ER to the plasma membrane (PM) via the interaction of their pleckstrin homology domains with phosphatidylinositol 4-phosphate (PI4P) in this membrane. Their OSBP-related domains (ORDs) harbored either PI4P or phosphatidylserine (PS) and exchanged these lipids between bilayers. Gain- and loss-of-function experiments showed that ORP5 and ORP8 could mediate PI4P/PS countertransport between the ER and the PM, thus delivering PI4P to the ER-localized PI4P phosphatase Sac1 for degradation and PS from the ER to the PM. This exchange helps to control plasma membrane PI4P levels and selectively enrich PS in the PM.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4638224/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4638224/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chung, Jeeyun -- Torta, Federico -- Masai, Kaori -- Lucast, Louise -- Czapla, Heather -- Tanner, Lukas B -- Narayanaswamy, Pradeep -- Wenk, Markus R -- Nakatsu, Fubito -- De Camilli, Pietro -- DA018343/DA/NIDA NIH HHS/ -- DK082700/DK/NIDDK NIH HHS/ -- DK45735/DK/NIDDK NIH HHS/ -- P30 DA018343/DA/NIDA NIH HHS/ -- P30 DK045735/DK/NIDDK NIH HHS/ -- R01 DK082700/DK/NIDDK NIH HHS/ -- R37 NS036251/NS/NINDS NIH HHS/ -- R37NS036251/NS/NINDS NIH HHS/ -- T32 GM007223/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jul 24;349(6246):428-32. doi: 10.1126/science.aab1370.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Howard Hughes Medical Institute, Kavli Institute for Neuroscience, and Program for Cellular Neuroscience, Neurodegeneration, and Repair, Yale School of Medicine, New Haven, CT 06520, USA. ; Department of Biochemistry, Yong Loo Lin School of Medicine, National University of Singapore, 117456 Singapore. ; Department of Cell Biology, Howard Hughes Medical Institute, Kavli Institute for Neuroscience, and Program for Cellular Neuroscience, Neurodegeneration, and Repair, Yale School of Medicine, New Haven, CT 06520, USA. pietro.decamilli@yale.edu nakatsu@med.niigata-u.ac.jp.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26206935" target="_blank"〉PubMed〈/a〉

    Description: Severe influenza disease strikes otherwise healthy children and remains unexplained. We report compound heterozygous null mutations in IRF7, which encodes the transcription factor interferon regulatory factor 7, in an otherwise healthy child who suffered life-threatening influenza during primary infection. In response to influenza virus, the patient's leukocytes and plasmacytoid dendritic cells produced very little type I and III interferons (IFNs). Moreover, the patient's dermal fibroblasts and induced pluripotent stem cell (iPSC)-derived pulmonary epithelial cells produced reduced amounts of type I IFN and displayed increased influenza virus replication. These findings suggest that IRF7-dependent amplification of type I and III IFNs is required for protection against primary infection by influenza virus in humans. They also show that severe influenza may result from single-gene inborn errors of immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431581/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431581/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ciancanelli, Michael J -- Huang, Sarah X L -- Luthra, Priya -- Garner, Hannah -- Itan, Yuval -- Volpi, Stefano -- Lafaille, Fabien G -- Trouillet, Celine -- Schmolke, Mirco -- Albrecht, Randy A -- Israelsson, Elisabeth -- Lim, Hye Kyung -- Casadio, Melina -- Hermesh, Tamar -- Lorenzo, Lazaro -- Leung, Lawrence W -- Pedergnana, Vincent -- Boisson, Bertrand -- Okada, Satoshi -- Picard, Capucine -- Ringuier, Benedicte -- Troussier, Francoise -- Chaussabel, Damien -- Abel, Laurent -- Pellier, Isabelle -- Notarangelo, Luigi D -- Garcia-Sastre, Adolfo -- Basler, Christopher F -- Geissmann, Frederic -- Zhang, Shen-Ying -- Snoeck, Hans-Willem -- Casanova, Jean-Laurent -- 1U19AI109945/AI/NIAID NIH HHS/ -- 5R01AI100887/AI/NIAID NIH HHS/ -- 5R01NS072381/NS/NINDS NIH HHS/ -- 8UL1TR000043/TR/NCATS NIH HHS/ -- HHSN272201400008C/PHS HHS/ -- R01 AI100887/AI/NIAID NIH HHS/ -- R01 NS072381/NS/NINDS NIH HHS/ -- U19 AI109945/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Apr 24;348(6233):448-53. doi: 10.1126/science.aaa1578.

    Description: Rgs2, a regulator of G proteins, lowers blood pressure by decreasing signaling through Galphaq. Human patients expressing Met-Leu-Rgs2 (ML-Rgs2) or Met-Arg-Rgs2 (MR-Rgs2) are hypertensive relative to people expressing wild-type Met-Gln-Rgs2 (MQ-Rgs2). We found that wild-type MQ-Rgs2 and its mutant, MR-Rgs2, were destroyed by the Ac/N-end rule pathway, which recognizes N(alpha)-terminally acetylated (Nt-acetylated) proteins. The shortest-lived mutant, ML-Rgs2, was targeted by both the Ac/N-end rule and Arg/N-end rule pathways. The latter pathway recognizes unacetylated N-terminal residues. Thus, the Nt-acetylated Ac-MX-Rgs2 (X = Arg, Gln, Leu) proteins are specific substrates of the mammalian Ac/N-end rule pathway. Furthermore, the Ac/N-degron of Ac-MQ-Rgs2 was conditional, and Teb4, an endoplasmic reticulum (ER) membrane-embedded ubiquitin ligase, was able to regulate G protein signaling by targeting Ac-MX-Rgs2 proteins for degradation through their N(alpha)-terminal acetyl group.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4748709/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4748709/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Park, Sang-Eun -- Kim, Jeong-Mok -- Seok, Ok-Hee -- Cho, Hanna -- Wadas, Brandon -- Kim, Seon-Young -- Varshavsky, Alexander -- Hwang, Cheol-Sang -- DK039520/DK/NIDDK NIH HHS/ -- GM031530/GM/NIGMS NIH HHS/ -- R01 DK039520/DK/NIDDK NIH HHS/ -- R01 GM031530/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1249-52. doi: 10.1126/science.aaa3844.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Life Sciences, Pohang University of Science and Technology, Pohang, Gyeongbuk 790-784, South Korea. ; Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA. ; Medical Genomics Research Center, KRIBB, Daejeon, South Korea.

    Description: Miocene small-bodied anthropoid primates from Africa and Eurasia are generally considered to precede the divergence between the two groups of extant catarrhines-hominoids (apes and humans) and Old World monkeys-and are thus viewed as more primitive than the stem ape Proconsul. Here we describe Pliobates cataloniae gen. et sp. nov., a small-bodied (4 to 5 kilograms) primate from the Iberian Miocene (11.6 million years ago) that displays a mosaic of primitive characteristics coupled with multiple cranial and postcranial shared derived features of extant hominoids. Our cladistic analyses show that Pliobates is a stem hominoid that is more derived than previously described small catarrhines and Proconsul. This forces us to reevaluate the role played by small-bodied catarrhines in ape evolution and provides key insight into the last common ancestor of hylobatids (gibbons) and hominids (great apes and humans).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alba, David M -- Almecija, Sergio -- DeMiguel, Daniel -- Fortuny, Josep -- Perez de los Rios, Miriam -- Pina, Marta -- Robles, Josep M -- Moya-Sola, Salvador -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):aab2625. doi: 10.1126/science.aab2625.

    Description: Telomerase helps maintain telomeres by processive synthesis of telomere repeat DNA at their 3'-ends, using an integral telomerase RNA (TER) and telomerase reverse transcriptase (TERT). We report the cryo-electron microscopy structure of Tetrahymena telomerase at ~9 angstrom resolution. In addition to seven known holoenzyme proteins, we identify two additional proteins that form a complex (TEB) with single-stranded telomere DNA-binding protein Teb1, paralogous to heterotrimeric replication protein A (RPA). The p75-p45-p19 subcomplex is identified as another RPA-related complex, CST (CTC1-STN1-TEN1). This study reveals the paths of TER in the TERT-TER-p65 catalytic core and single-stranded DNA exit; extensive subunit interactions of the TERT essential N-terminal domain, p50, and TEB; and other subunit identities and structures, including p19 and p45C crystal structures. Our findings provide structural and mechanistic insights into telomerase holoenzyme function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687456/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Jiansen -- Chan, Henry -- Cash, Darian D -- Miracco, Edward J -- Ogorzalek Loo, Rachel R -- Upton, Heather E -- Cascio, Duilio -- O'Brien Johnson, Reid -- Collins, Kathleen -- Loo, Joseph A -- Zhou, Z Hong -- Feigon, Juli -- GM007185/GM/NIGMS NIH HHS/ -- GM048123/GM/NIGMS NIH HHS/ -- GM071940/GM/NIGMS NIH HHS/ -- GM101874/GM/NIGMS NIH HHS/ -- GM103479/GM/NIGMS NIH HHS/ -- P41 GM103403/GM/NIGMS NIH HHS/ -- P41 RR015301/RR/NCRR NIH HHS/ -- R01 GM048123/GM/NIGMS NIH HHS/ -- R01 GM054198/GM/NIGMS NIH HHS/ -- R01 GM071940/GM/NIGMS NIH HHS/ -- R01 GM103479/GM/NIGMS NIH HHS/ -- R01GM054198/GM/NIGMS NIH HHS/ -- S10OD018111/OD/NIH HHS/ -- S10RR23057/RR/NCRR NIH HHS/ -- UL1TR000124/TR/NCATS NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):aab4070. doi: 10.1126/science.aab4070.
