    Description: Insulin-induced gene 1 (Insig-1) and Insig-2 are endoplasmic reticulum membrane-embedded sterol sensors that regulate the cellular accumulation of sterols. Despite their physiological importance, the structural information on Insigs remains limited. Here we report the high-resolution structures of MvINS, an Insig homolog from Mycobacterium vanbaalenii. MvINS exists as a homotrimer. Each protomer comprises six transmembrane segments (TMs), with TM3 and TM4 contributing to homotrimerization. The six TMs enclose a V-shaped cavity that can accommodate a diacylglycerol molecule. A homology-based structural model of human Insig-2, together with biochemical characterizations, suggest that the central cavity of Insig-2 accommodates 25-hydroxycholesterol, whereas TM3 and TM4 engage in Scap binding. These analyses provide an important framework for further functional and mechanistic understanding of Insig proteins and the sterol regulatory element-binding protein pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4704858/" 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/PMC4704858/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ren, Ruobing -- Zhou, Xinhui -- He, Yuan -- Ke, Meng -- Wu, Jianping -- Liu, Xiaohui -- Yan, Chuangye -- Wu, Yixuan -- Gong, Xin -- Lei, Xiaoguang -- Yan, S Frank -- Radhakrishnan, Arun -- Yan, Nieng -- HL-20948/HL/NHLBI NIH HHS/ -- P01 HL020948/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jul 10;349(6244):187-91. doi: 10.1126/science.aab1091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Membrane Biology, Tsinghua University, Beijing 100084, China.

    Description: Proton-pumping complex I of the mitochondrial respiratory chain is among the largest and most complicated membrane protein complexes. The enzyme contributes substantially to oxidative energy conversion in eukaryotic cells. Its malfunctions are implicated in many hereditary and degenerative disorders. We report the x-ray structure of mitochondrial complex I at a resolution of 3.6 to 3.9 angstroms, describing in detail the central subunits that execute the bioenergetic function. A continuous axis of basic and acidic residues running centrally through the membrane arm connects the ubiquinone reduction site in the hydrophilic arm to four putative proton-pumping units. The binding position for a substrate analogous inhibitor and blockage of the predicted ubiquinone binding site provide a model for the "deactive" form of the enzyme. The proposed transition into the active form is based on a concerted structural rearrangement at the ubiquinone reduction site, providing support for a two-state stabilization-change mechanism of proton pumping.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zickermann, Volker -- Wirth, Christophe -- Nasiri, Hamid -- Siegmund, Karin -- Schwalbe, Harald -- Hunte, Carola -- Brandt, Ulrich -- New York, N.Y. -- Science. 2015 Jan 2;347(6217):44-9. doi: 10.1126/science.1259859.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Bioenergetics Group, Institute of Biochemistry II, Medical School, Goethe-University, 60438 Frankfurt am Main, Germany.

    Description: Lactic acid racemization is involved in lactate metabolism and cell wall assembly of many microorganisms. Lactate racemase (Lar) requires nickel, but the nickel-binding site and the role of three accessory proteins required for its activation remain enigmatic. We combined mass spectrometry and x-ray crystallography to show that Lar from Lactobacillus plantarum possesses an organometallic nickel-containing prosthetic group. A nicotinic acid mononucleotide derivative is tethered to Lys(184) and forms a tridentate pincer complex that coordinates nickel through one metal-carbon and two metal-sulfur bonds, with His(200) as another ligand. Although similar complexes have been previously synthesized, there was no prior evidence for the existence of pincer cofactors in enzymes. The wide distribution of the accessory proteins without Lar suggests that it may play a role in other enzymes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Desguin, Benoit -- Zhang, Tuo -- Soumillion, Patrice -- Hols, Pascal -- Hu, Jian -- Hausinger, Robert P -- New York, N.Y. -- Science. 2015 Jul 3;349(6243):66-9. doi: 10.1126/science.aab2272.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Michigan State University, East Lansing, MI 48824, USA. ; Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, MI 48824, USA. ; Institute of Life Sciences, Universite Catholique de Louvain, B-1348 Louvain-la-Neuve, Belgium. ; Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, MI 48824, USA.

    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: Phosphatidylinositol 3-kinase Vps34 complexes regulate intracellular membrane trafficking in endocytic sorting, cytokinesis, and autophagy. We present the 4.4 angstrom crystal structure of the 385-kilodalton endosomal complex II (PIK3C3-CII), consisting of Vps34, Vps15 (p150), Vps30/Atg6 (Beclin 1), and Vps38 (UVRAG). The subunits form a Y-shaped complex, centered on the Vps34 C2 domain. Vps34 and Vps15 intertwine in one arm, where the Vps15 kinase domain engages the Vps34 activation loop to regulate its activity. Vps30 and Vps38 form the other arm that brackets the Vps15/Vps34 heterodimer, suggesting a path for complex assembly. We used hydrogen-deuterium exchange mass spectrometry (HDX-MS) to reveal conformational changes accompanying membrane binding and identify a Vps30 loop that is critical for the ability of complex II to phosphorylate giant liposomes on which complex I is inactive.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4601532/" 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/PMC4601532/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rostislavleva, Ksenia -- Soler, Nicolas -- Ohashi, Yohei -- Zhang, Lufei -- Pardon, Els -- Burke, John E -- Masson, Glenn R -- Johnson, Chris -- Steyaert, Jan -- Ktistakis, Nicholas T -- Williams, Roger L -- BB/K019155/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- MC_U105184308/Medical Research Council/United Kingdom -- PG11/109/29247/British Heart Foundation/United Kingdom -- U105184308/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):aac7365. doi: 10.1126/science.aac7365.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. ; Structural Biology Research Center, VIB, B-1050 Brussels, Belgium.

    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: Massive data collection by businesses and governments calls into question traditional methods for protecting privacy, underpinned by two core principles: (i) notice, that there should be no data collection system whose existence is secret, and (ii) consent, that data collected for one purpose not be used for another without user permission. But notice, designated as a fundamental privacy principle in a different era, makes little sense in situations where collection consists of lots and lots of small amounts of information, whereas consent is no longer realistic, given the complexity and number of decisions that must be made. Thus, efforts to protect privacy by controlling use of data are gaining more attention. I discuss relevant technology, policy, and law, as well as some examples that can illuminate the way.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landau, Susan -- New York, N.Y. -- Science. 2015 Jan 30;347(6221):504-6. doi: 10.1126/science.aaa4961.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Worcester Polytechnic Institute, Worcester, MA 01609, USA. susan.landau@privacyink.org.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25635089" target="_blank"〉PubMed〈/a〉

    Description: In eukaryotic cells, phosphatidylserine (PS) is synthesized in the endoplasmic reticulum (ER) but is highly enriched in the plasma membrane (PM), where it contributes negative charge and to specific recruitment of signaling proteins. This distribution relies on transport mechanisms whose nature remains elusive. Here, we found that the PS transporter Osh6p extracted phosphatidylinositol 4-phosphate (PI4P) and exchanged PS for PI4P between two membranes. We solved the crystal structure of Osh6p:PI4P complex and demonstrated that the transport of PS by Osh6p depends on PI4P recognition in vivo. Finally, we showed that the PI4P-phosphatase Sac1p, by maintaining a PI4P gradient at the ER/PM interface, drove PS transport. Thus, PS transport by oxysterol-binding protein-related protein (ORP)/oxysterol-binding homology (Osh) proteins is fueled by PI4P metabolism through PS/PI4P exchange cycles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moser von Filseck, Joachim -- Copic, Alenka -- Delfosse, Vanessa -- Vanni, Stefano -- Jackson, Catherine L -- Bourguet, William -- Drin, Guillaume -- New York, N.Y. -- Science. 2015 Jul 24;349(6246):432-6. doi: 10.1126/science.aab1346.

    Description: Microbial sulfate reduction has governed Earth's biogeochemical sulfur cycle for at least 2.5 billion years. However, the enzymatic mechanisms behind this pathway are incompletely understood, particularly for the reduction of sulfite-a key intermediate in the pathway. This critical reaction is performed by DsrAB, a widespread enzyme also involved in other dissimilatory sulfur metabolisms. Using in vitro assays with an archaeal DsrAB, supported with genetic experiments in a bacterial system, we show that the product of sulfite reduction by DsrAB is a protein-based trisulfide, in which a sulfite-derived sulfur is bridging two conserved cysteines of DsrC. Physiological studies also reveal that sulfate reduction rates are determined by cellular levels of DsrC. Dissimilatory sulfate reduction couples the four-electron reduction of the DsrC trisulfide to energy conservation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Santos, Andre A -- Venceslau, Sofia S -- Grein, Fabian -- Leavitt, William D -- Dahl, Christiane -- Johnston, David T -- Pereira, Ines A C -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):1541-5. doi: 10.1126/science.aad3558.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Instituto de Tecnologia Quimica e Biologica Antonio Xavier, Universidade Nova de Lisboa, Oeiras, Portugal. ; Department of Earth and Planetary Science, Harvard University, Cambridge, MA, USA. ; Institut fur Mikrobiologie & Biotechnologie, Rheinische Friedrich-Wilhelms-Universitat Bonn, Germany. ; Instituto de Tecnologia Quimica e Biologica Antonio Xavier, Universidade Nova de Lisboa, Oeiras, Portugal. ipereira@itqb.unl.pt.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26680199" target="_blank"〉PubMed〈/a〉

    Description: Chemokines are small proteins that function as immune modulators through activation of chemokine G protein-coupled receptors (GPCRs). Several viruses also encode chemokines and chemokine receptors to subvert the host immune response. How protein ligands activate GPCRs remains unknown. We report the crystal structure at 2.9 angstrom resolution of the human cytomegalovirus GPCR US28 in complex with the chemokine domain of human CX3CL1 (fractalkine). The globular body of CX3CL1 is perched on top of the US28 extracellular vestibule, whereas its amino terminus projects into the central core of US28. The transmembrane helices of US28 adopt an active-state-like conformation. Atomic-level simulations suggest that the agonist-independent activity of US28 may be due to an amino acid network evolved in the viral GPCR to destabilize the receptor's inactive state.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4445376/" 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/PMC4445376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burg, John S -- Ingram, Jessica R -- Venkatakrishnan, A J -- Jude, Kevin M -- Dukkipati, Abhiram -- Feinberg, Evan N -- Angelini, Alessandro -- Waghray, Deepa -- Dror, Ron O -- Ploegh, Hidde L -- Garcia, K Christopher -- DP1 GM106409/GM/NIGMS NIH HHS/ -- R01 GM097015/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 6;347(6226):1113-7. doi: 10.1126/science.aaa5026.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University School of Medicine, Stanford, CA 94305, USA.

    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: Pigment-protein and pigment-pigment interactions are of fundamental importance to the light-harvesting and photoprotective functions essential to oxygenic photosynthesis. The orange carotenoid protein (OCP) functions as both a sensor of light and effector of photoprotective energy dissipation in cyanobacteria. We report the atomic-resolution structure of an active form of the OCP consisting of the N-terminal domain and a single noncovalently bound carotenoid pigment. The crystal structure, combined with additional solution-state structural data, reveals that OCP photoactivation is accompanied by a 12 angstrom translocation of the pigment within the protein and a reconfiguration of carotenoid-protein interactions. Our results identify the origin of the photochromic changes in the OCP triggered by light and reveal the structural determinants required for interaction with the light-harvesting antenna during photoprotection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leverenz, Ryan L -- Sutter, Markus -- Wilson, Adjele -- Gupta, Sayan -- Thurotte, Adrien -- Bourcier de Carbon, Celine -- Petzold, Christopher J -- Ralston, Corie -- Perreau, Francois -- Kirilovsky, Diana -- Kerfeld, Cheryl A -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jun 26;348(6242):1463-6. doi: 10.1126/science.aaa7234.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MSU-DOE Plant Research Laboratory, Michigan State University, East Lansing, MI 48824, USA. ; MSU-DOE Plant Research Laboratory, Michigan State University, East Lansing, MI 48824, USA.

    Description: This paper examines the success of peer-review panels in predicting the future quality of proposed research. We construct new data to track publication, citation, and patenting outcomes associated with more than 130,000 research project (R01) grants funded by the U.S. National Institutes of Health from 1980 to 2008. We find that better peer-review scores are consistently associated with better research outcomes and that this relationship persists even when we include detailed controls for an investigator's publication history, grant history, institutional affiliations, career stage, and degree types. A one-standard deviation worse peer-review score among awarded grants is associated with 15% fewer citations, 7% fewer publications, 19% fewer high-impact publications, and 14% fewer follow-on patents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Danielle -- Agha, Leila -- New York, N.Y. -- Science. 2015 Apr 24;348(6233):434-8. doi: 10.1126/science.aaa0185.

    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: We studied the distributional preferences of an elite cadre of Yale Law School students, a group that will assume positions of power in U.S. society. Our experimental design allows us to test whether redistributive decisions are consistent with utility maximization and to decompose underlying preferences into two qualitatively different tradeoffs: fair-mindedness versus self-interest, and equality versus efficiency. Yale Law School subjects are more consistent than subjects drawn from the American Life Panel, a diverse sample of Americans. Relative to the American Life Panel, Yale Law School subjects are also less fair-minded and substantially more efficiency-focused. We further show that our measure of equality-efficiency tradeoffs predicts Yale Law School students' career choices: Equality-minded subjects are more likely to be employed at nonprofit organizations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fisman, Raymond -- Jakiela, Pamela -- Kariv, Shachar -- Markovits, Daniel -- New York, N.Y. -- Science. 2015 Sep 18;349(6254):aab0096. doi: 10.1126/science.aab0096.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, Boston University, Boston, MA, USA. rfisman@bu.edu. ; Department of Agricultural and Resource Economics, University of Maryland, College Park, MD, USA. ; Department of Economics, University of California, Berkeley, Berkely, CA, USA. ; Yale Law School, Yale University, New Haven, CT, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26383958" target="_blank"〉PubMed〈/a〉

    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: XRCC4 and XLF are two structurally related proteins that function in DNA double-strand break (DSB) repair. Here, we identify human PAXX (PAralog of XRCC4 and XLF, also called C9orf142) as a new XRCC4 superfamily member and show that its crystal structure resembles that of XRCC4. PAXX interacts directly with the DSB-repair protein Ku and is recruited to DNA-damage sites in cells. Using RNA interference and CRISPR-Cas9 to generate PAXX(-/-) cells, we demonstrate that PAXX functions with XRCC4 and XLF to mediate DSB repair and cell survival in response to DSB-inducing agents. Finally, we reveal that PAXX promotes Ku-dependent DNA ligation in vitro and assembly of core nonhomologous end-joining (NHEJ) factors on damaged chromatin in cells. These findings identify PAXX as a new component of the NHEJ machinery.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4338599/" 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/PMC4338599/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ochi, Takashi -- Blackford, Andrew N -- Coates, Julia -- Jhujh, Satpal -- Mehmood, Shahid -- Tamura, Naoka -- Travers, Jon -- Wu, Qian -- Draviam, Viji M -- Robinson, Carol V -- Blundell, Tom L -- Jackson, Stephen P -- 11224/Cancer Research UK/United Kingdom -- 268536/European Research Council/International -- A11224/Cancer Research UK/United Kingdom -- C28598/A9787/Cancer Research UK/United Kingdom -- C6/A11224/Cancer Research UK/United Kingdom -- C6946/A14492/Cancer Research UK/United Kingdom -- WT092096/Wellcome Trust/United Kingdom -- WT093167/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Jan 9;347(6218):185-8. doi: 10.1126/science.1261971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Cambridge, 80 Tennis Court Road, Cambridge CB2 1GA, UK. ; Wellcome Trust/Cancer Research UK Gurdon Institute, University of Cambridge, Tennis Court Road, Cambridge CB2 1QN, UK. ; Physical and Theoretical Chemistry Laboratory, University of Oxford, South Parks Road, Oxford OX1 3QZ, UK. ; Department of Genetics, University of Cambridge, Cambridge CB2 3EH, UK. ; Department of Biochemistry, University of Cambridge, 80 Tennis Court Road, Cambridge CB2 1GA, UK. s.jackson@gurdon.cam.ac.uk tlb20@cam.ac.uk. ; Department of Biochemistry, University of Cambridge, 80 Tennis Court Road, Cambridge CB2 1GA, UK.

    Description: Circadian clocks generate slow and ordered cellular dynamics but consist of fast-moving bio-macromolecules; consequently, the origins of the overall slowness remain unclear. We identified the adenosine triphosphate (ATP) catalytic region [adenosine triphosphatase (ATPase)] in the amino-terminal half of the clock protein KaiC as the minimal pacemaker that controls the in vivo frequency of the cyanobacterial clock. Crystal structures of the ATPase revealed that the slowness of this ATPase arises from sequestration of a lytic water molecule in an unfavorable position and coupling of ATP hydrolysis to a peptide isomerization with high activation energy. The slow ATPase is coupled with another ATPase catalyzing autodephosphorylation in the carboxyl-terminal half of KaiC, yielding the circadian response frequency of intermolecular interactions with other clock-related proteins that influences the transcription and translation cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abe, Jun -- Hiyama, Takuya B -- Mukaiyama, Atsushi -- Son, Seyoung -- Mori, Toshifumi -- Saito, Shinji -- Osako, Masato -- Wolanin, Julie -- Yamashita, Eiki -- Kondo, Takao -- Akiyama, Shuji -- New York, N.Y. -- Science. 2015 Jul 17;349(6245):312-6. doi: 10.1126/science.1261040.

    Description: Enterovirus D68 (EV-D68) is a member of Picornaviridae and is a causative agent of recent outbreaks of respiratory illness in children in the United States. We report here the crystal structures of EV-D68 and its complex with pleconaril, a capsid-binding compound that had been developed as an anti-rhinovirus drug. The hydrophobic drug-binding pocket in viral protein 1 contained density that is consistent with a fatty acid of about 10 carbon atoms. This density could be displaced by pleconaril. We also showed that pleconaril inhibits EV-D68 at a half-maximal effective concentration of 430 nanomolar and might, therefore, be a possible drug candidate to alleviate EV-D68 outbreaks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4307789/" 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/PMC4307789/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Yue -- Sheng, Ju -- Fokine, Andrei -- Meng, Geng -- Shin, Woong-Hee -- Long, Feng -- Kuhn, Richard J -- Kihara, Daisuke -- Rossmann, Michael G -- AI11219/AI/NIAID NIH HHS/ -- R24 GM111072/GM/NIGMS NIH HHS/ -- R37 AI011219/AI/NIAID NIH HHS/ -- RR007707/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2015 Jan 2;347(6217):71-4. doi: 10.1126/science.1261962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Hockmeyer Hall of Structural Biology, 240 South Martin Jischke Drive, Purdue University, West Lafayette, IN 47907, USA. ; Department of Biological Sciences, Hockmeyer Hall of Structural Biology, 240 South Martin Jischke Drive, Purdue University, West Lafayette, IN 47907, USA.

    Description: Nuclear pore complexes (NPCs) conduct nucleocytoplasmic transport and gain transport selectivity through nucleoporin FG domains. Here, we report a structural analysis of the FG Nup62*58*54 complex, which is a crucial component of the transport system. It comprises a approximately 13 nanometer-long trimerization interface with an unusual 2W3F coil, a canonical heterotrimeric coiled coil, and a kink that enforces a compact six-helix bundle. Nup54 also contains a ferredoxin-like domain. We further identified a heterotrimeric Nup93-binding module for NPC anchorage. The quaternary structure alternations in the Nup62 complex, which were previously proposed to trigger a general gating of the NPC, are incompatible with the trimer structure. We suggest that the highly elongated Nup62 complex projects barrier-forming FG repeats far into the central NPC channel, supporting a barrier that guards the entire cross section.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chug, Hema -- Trakhanov, Sergei -- Hulsmann, Bastian B -- Pleiner, Tino -- Gorlich, Dirk -- New York, N.Y. -- Science. 2015 Oct 2;350(6256):106-10. doi: 10.1126/science.aac7420.

    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: 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.

    Description: Bacterial adaptive immunity uses CRISPR (clustered regularly interspaced short palindromic repeats)-associated (Cas) proteins together with CRISPR transcripts for foreign DNA degradation. In type II CRISPR-Cas systems, activation of Cas9 endonuclease for DNA recognition upon guide RNA binding occurs by an unknown mechanism. Crystal structures of Cas9 bound to single-guide RNA reveal a conformation distinct from both the apo and DNA-bound states, in which the 10-nucleotide RNA "seed" sequence required for initial DNA interrogation is preordered in an A-form conformation. This segment of the guide RNA is essential for Cas9 to form a DNA recognition-competent structure that is poised to engage double-stranded DNA target sequences. We construe this as convergent evolution of a "seed" mechanism reminiscent of that used by Argonaute proteins during RNA interference in eukaryotes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Fuguo -- Zhou, Kaihong -- Ma, Linlin -- Gressel, Saskia -- Doudna, Jennifer A -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jun 26;348(6242):1477-81. doi: 10.1126/science.aab1452.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720, USA. ; Howard Hughes Medical Institute, University of California, Berkeley, CA 94720, USA. ; Max Planck Institute for Biophysical Chemistry, 37077 Gottingen, Germany. ; Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720, USA.

    Description: Polycomb repressive complex 2 (PRC2) catalyzes histone H3K27 trimethylation (H3K27me3), a hallmark of gene silencing. Here we report the crystal structures of an active PRC2 complex of 170 kilodaltons from the yeast Chaetomium thermophilum in both basal and stimulated states, which contain Ezh2, Eed, and the VEFS domain of Suz12 and are bound to a cancer-associated inhibiting H3K27M peptide and a S-adenosyl-l-homocysteine cofactor. The stimulated complex also contains an additional stimulating H3K27me3 peptide. Eed is engulfed by a belt-like structure of Ezh2, and Suz12(VEFS) contacts both of these two subunits to confer an unusual split active SET domain for catalysis. Comparison of PRC2 in the basal and stimulated states reveals a mobile Ezh2 motif that responds to stimulation to allosterically regulate the active site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiao, Lianying -- Liu, Xin -- GM114576/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 16;350(6258):aac4383. doi: 10.1126/science.aac4383.

    Description: The fleeting lifetimes of the transition states (TSs) of chemical reactions make determination of their three-dimensional structures by diffraction methods a challenge. Here, we used packing interactions within the core of a protein to stabilize the planar TS conformation for rotation around the central carbon-carbon bond of biphenyl so that it could be directly observed by x-ray crystallography. The computational protein design software Rosetta was used to design a pocket within threonyl-transfer RNA synthetase from the thermophile Pyrococcus abyssi that forms complementary van der Waals interactions with a planar biphenyl. This latter moiety was introduced biosynthetically as the side chain of the noncanonical amino acid p-biphenylalanine. Through iterative rounds of computational design and structural analysis, we identified a protein in which the side chain of p-biphenylalanine is trapped in the energetically disfavored, coplanar conformation of the TS of the bond rotation reaction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4581533/" 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/PMC4581533/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearson, Aaron D -- Mills, Jeremy H -- Song, Yifan -- Nasertorabi, Fariborz -- Han, Gye Won -- Baker, David -- Stevens, Raymond C -- Schultz, Peter G -- 2 R01 GM097206-05/GM/NIGMS NIH HHS/ -- F32 GM099210/GM/NIGMS NIH HHS/ -- F32GM099210/GM/NIGMS NIH HHS/ -- R01 GM097206/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):863-7. doi: 10.1126/science.aaa2424.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Skaggs Institute for Chemical Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. ; Department of Biochemistry, University of Washington, Seattle, WA 98195, USA. ; Department of Biological Sciences, Bridge Institute, University of Southern California, Los Angeles, CA 90089, USA. ; Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.

    Description: Notch receptors guide mammalian cell fate decisions by engaging the proteins Jagged and Delta-like (DLL). The 2.3 angstrom resolution crystal structure of the interacting regions of the Notch1-DLL4 complex reveals a two-site, antiparallel binding orientation assisted by Notch1 O-linked glycosylation. Notch1 epidermal growth factor-like repeats 11 and 12 interact with the DLL4 Delta/Serrate/Lag-2 (DSL) domain and module at the N-terminus of Notch ligands (MNNL) domains, respectively. Threonine and serine residues on Notch1 are functionalized with O-fucose and O-glucose, which act as surrogate amino acids by making specific, and essential, contacts to residues on DLL4. The elucidation of a direct chemical role for O-glycans in Notch1 ligand engagement demonstrates how, by relying on posttranslational modifications of their ligand binding sites, Notch proteins have linked their functional capacity to developmentally regulated biosynthetic pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4445638/" 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/PMC4445638/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luca, Vincent C -- Jude, Kevin M -- Pierce, Nathan W -- Nachury, Maxence V -- Fischer, Suzanne -- Garcia, K Christopher -- 1R01-GM097015/GM/NIGMS NIH HHS/ -- R01 GM097015/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):847-53. doi: 10.1126/science.1261093.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University School of Medicine, Stanford, CA 94305, USA.

    Description: The highly divergent ribosomes of human mitochondria (mitoribosomes) synthesize 13 essential proteins of oxidative phosphorylation complexes. We have determined the structure of the intact mitoribosome to 3.5 angstrom resolution by means of single-particle electron cryogenic microscopy. It reveals 80 extensively interconnected proteins, 36 of which are specific to mitochondria, and three ribosomal RNA molecules. The head domain of the small subunit, particularly the messenger (mRNA) channel, is highly remodeled. Many intersubunit bridges are specific to the mitoribosome, which adopts conformations involving ratcheting or rolling of the small subunit that are distinct from those seen in bacteria or eukaryotes. An intrinsic guanosine triphosphatase mediates a contact between the head and central protuberance. The structure provides a reference for analysis of mutations that cause severe pathologies and for future drug design.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4501431/" 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/PMC4501431/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amunts, Alexey -- Brown, Alan -- Toots, Jaan -- Scheres, Sjors H W -- Ramakrishnan, V -- 096570/Wellcome Trust/United Kingdom -- MC_U105184332/Medical Research Council/United Kingdom -- MC_UP_A025_1013/Medical Research Council/United Kingdom -- WT096570/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):95-8. doi: 10.1126/science.aaa1193.

    Description: The impacts of climate extremes on terrestrial ecosystems are poorly understood but important for predicting carbon cycle feedbacks to climate change. Coupled climate-carbon cycle models typically assume that vegetation recovery from extreme drought is immediate and complete, which conflicts with the understanding of basic plant physiology. We examined the recovery of stem growth in trees after severe drought at 1338 forest sites across the globe, comprising 49,339 site-years, and compared the results with simulated recovery in climate-vegetation models. We found pervasive and substantial "legacy effects" of reduced growth and incomplete recovery for 1 to 4 years after severe drought. Legacy effects were most prevalent in dry ecosystems, among Pinaceae, and among species with low hydraulic safety margins. In contrast, limited or no legacy effects after drought were simulated by current climate-vegetation models. Our results highlight hysteresis in ecosystem-level carbon cycling and delayed recovery from climate extremes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderegg, W R L -- Schwalm, C -- Biondi, F -- Camarero, J J -- Koch, G -- Litvak, M -- Ogle, K -- Shaw, J D -- Shevliakova, E -- Williams, A P -- Wolf, A -- Ziaco, E -- Pacala, S -- New York, N.Y. -- Science. 2015 Jul 31;349(6247):528-32. doi: 10.1126/science.aab1833.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA.

    Description: The development of effective pharmacological inhibitors of multidomain scaffold proteins, notably transcription factors, is a particularly challenging problem. In part, this is because many small-molecule antagonists disrupt the activity of only one domain in the target protein. We devised a chemical strategy that promotes ligand-dependent target protein degradation using as an example the transcriptional coactivator BRD4, a protein critical for cancer cell growth and survival. We appended a competitive antagonist of BET bromodomains to a phthalimide moiety to hijack the cereblon E3 ubiquitin ligase complex. The resultant compound, dBET1, induced highly selective cereblon-dependent BET protein degradation in vitro and in vivo and delayed leukemia progression in mice. A second series of probes resulted in selective degradation of the cytosolic protein FKBP12. This chemical strategy for controlling target protein stability may have implications for therapeutically targeting previously intractable proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winter, Georg E -- Buckley, Dennis L -- Paulk, Joshiawa -- Roberts, Justin M -- Souza, Amanda -- Dhe-Paganon, Sirano -- Bradner, James E -- P01 CA066996/CA/NCI NIH HHS/ -- P01-CA066996/CA/NCI NIH HHS/ -- R01-CA176745/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Jun 19;348(6241):1376-81. doi: 10.1126/science.aab1433.

    Description: Research suggesting that political conservatives are happier than political liberals has relied exclusively on self-report measures of subjective well-being. We show that this finding is fully mediated by conservatives' self-enhancing style of self-report (study 1; N = 1433) and then describe three studies drawing from "big data" sources to assess liberal-conservative differences in happiness-related behavior (studies 2 to 4; N = 4936). Relative to conservatives, liberals more frequently used positive emotional language in their speech and smiled more intensely and genuinely in photographs. Our results were consistent across large samples of online survey takers, U.S. politicians, Twitter users, and LinkedIn users. Our findings illustrate the nuanced relationship between political ideology, self-enhancement, and happiness and illuminate the contradictory ways that happiness differences can manifest across behavior and self-reports.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wojcik, Sean P -- Hovasapian, Arpine -- Graham, Jesse -- Motyl, Matt -- Ditto, Peter H -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1243-6. doi: 10.1126/science.1260817.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Social Behavior, University of California, Irvine, CA 92697, USA. swojcik@uci.edu phditto@uci.edu. ; Department of Psychology and Social Behavior, University of California, Irvine, CA 92697, USA. ; Department of Psychology, University of Southern California, CA 90089, USA. ; University of Illinois, Chicago, IL 60607, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25766233" target="_blank"〉PubMed〈/a〉
