    Description: The field of optogenetics uses channelrhodopsins (ChRs) for light-induced neuronal activation. However, optimized tools for cellular inhibition at moderate light levels are lacking. We found that replacement of E90 in the central gate of ChR with positively charged residues produces chloride-conducting ChRs (ChloCs) with only negligible cation conductance. Molecular dynamics modeling unveiled that a high-affinity Cl(-)-binding site had been generated near the gate. Stabilizing the open state dramatically increased the operational light sensitivity of expressing cells (slow ChloC). In CA1 pyramidal cells, ChloCs completely inhibited action potentials triggered by depolarizing current injections or synaptic stimulation. Thus, by inverting the charge of the selectivity filter, we have created a class of directly light-gated anion channels that can be used to block neuronal output in a fully reversible fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wietek, Jonas -- Wiegert, J Simon -- Adeishvili, Nona -- Schneider, Franziska -- Watanabe, Hiroshi -- Tsunoda, Satoshi P -- Vogt, Arend -- Elstner, Marcus -- Oertner, Thomas G -- Hegemann, Peter -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):409-12. doi: 10.1126/science.1249375.

    Description: The excitatory neurotransmitter glutamate induces modulatory actions via the metabotropic glutamate receptors (mGlus), which are class C G protein-coupled receptors (GPCRs). We determined the structure of the human mGlu1 receptor seven-transmembrane (7TM) domain bound to a negative allosteric modulator, FITM, at a resolution of 2.8 angstroms. The modulator binding site partially overlaps with the orthosteric binding sites of class A GPCRs but is more restricted than most other GPCRs. We observed a parallel 7TM dimer mediated by cholesterols, which suggests that signaling initiated by glutamate's interaction with the extracellular domain might be mediated via 7TM interactions within the full-length receptor dimer. A combination of crystallography, structure-activity relationships, mutagenesis, and full-length dimer modeling provides insights about the allosteric modulation and activation mechanism of class C GPCRs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991565/" 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/PMC3991565/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Huixian -- Wang, Chong -- Gregory, Karen J -- Han, Gye Won -- Cho, Hyekyung P -- Xia, Yan -- Niswender, Colleen M -- Katritch, Vsevolod -- Meiler, Jens -- Cherezov, Vadim -- Conn, P Jeffrey -- Stevens, Raymond C -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DK097376/DK/NIDDK NIH HHS/ -- R01 GM080403/GM/NIGMS NIH HHS/ -- R01 GM099842/GM/NIGMS NIH HHS/ -- R01 MH062646/MH/NIMH NIH HHS/ -- R01 MH090192/MH/NIMH NIH HHS/ -- R01 NS031373/NS/NINDS NIH HHS/ -- R21 NS078262/NS/NINDS NIH HHS/ -- R37 NS031373/NS/NINDS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):58-64. doi: 10.1126/science.1249489.

    Description: The hierarchical packaging of eukaryotic chromatin plays a central role in transcriptional regulation and other DNA-related biological processes. Here, we report the 11-angstrom-resolution cryogenic electron microscopy (cryo-EM) structures of 30-nanometer chromatin fibers reconstituted in the presence of linker histone H1 and with different nucleosome repeat lengths. The structures show a histone H1-dependent left-handed twist of the repeating tetranucleosomal structural units, within which the four nucleosomes zigzag back and forth with a straight linker DNA. The asymmetric binding and the location of histone H1 in chromatin play a role in the formation of the 30-nanometer fiber. Our results provide mechanistic insights into how nucleosomes compact into higher-order chromatin fibers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Feng -- Chen, Ping -- Sun, Dapeng -- Wang, Mingzhu -- Dong, Liping -- Liang, Dan -- Xu, Rui-Ming -- Zhu, Ping -- Li, Guohong -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):376-80. doi: 10.1126/science.1251413.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Laboratory of Biomacromolecules, Institute of Biophysics, Chinese Academy of Sciences, Beijing 100101, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24763583" target="_blank"〉PubMed〈/a〉

    Description: This Review presents basic facts regarding the long-run evolution of income and wealth inequality in Europe and the United States. Income and wealth inequality was very high a century ago, particularly in Europe, but dropped dramatically in the first half of the 20th century. Income inequality has surged back in the United States since the 1970s so that the United States is much more unequal than Europe today. We discuss possible interpretations and lessons for the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Piketty, Thomas -- Saez, Emmanuel -- New York, N.Y. -- Science. 2014 May 23;344(6186):838-43. doi: 10.1126/science.1251936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, Paris School of Economics, Paris, France. thomas.piketty@psemail.eu. ; Department of Economics, University of California at Berkeley, Berkeley, CA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24855258" target="_blank"〉PubMed〈/a〉

    Description: Lightning plays an important role in atmospheric chemistry and in the initiation of wildfires, but the impact of global warming on lightning rates is poorly constrained. Here we propose that the lightning flash rate is proportional to the convective available potential energy (CAPE) times the precipitation rate. Using observations, the product of CAPE and precipitation explains 77% of the variance in the time series of total cloud-to-ground lightning flashes over the contiguous United States (CONUS). Storms convert CAPE times precipitated water mass to discharged lightning energy with an efficiency of 1%. When this proxy is applied to 11 climate models, CONUS lightning strikes are predicted to increase 12 +/- 5% per degree Celsius of global warming and about 50% over this century.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Romps, David M -- Seeley, Jacob T -- Vollaro, David -- Molinari, John -- New York, N.Y. -- Science. 2014 Nov 14;346(6211):851-4. doi: 10.1126/science.1259100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Science, University of California, Berkeley, and Earth Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, CA, USA. romps@berkeley.edu. ; Department of Earth and Planetary Science, University of California, Berkeley, and Earth Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, CA, USA. ; Department of Atmospheric and Environmental Sciences, State University of New York at Albany, Albany, NY, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25395536" target="_blank"〉PubMed〈/a〉

    Description: Although substantial progress has been achieved in the structural analysis of exporters from the superfamily of adenosine triphosphate (ATP)-binding cassette (ABC) transporters, much less is known about how they selectively recognize substrates and how substrate binding is coupled to ATP hydrolysis. We have addressed these questions through crystallographic analysis of the Atm1/ABCB7/HMT1/ABCB6 ortholog from Novosphingobium aromaticivorans DSM 12444, NaAtm1, at 2.4 angstrom resolution. Consistent with a physiological role in cellular detoxification processes, functional studies showed that glutathione derivatives can serve as substrates for NaAtm1 and that its overexpression in Escherichia coli confers protection against silver and mercury toxicity. The glutathione binding site highlights the articulated design of ABC exporters, with ligands and nucleotides spanning structurally conserved elements to create adaptable interfaces accommodating conformational rearrangements during the transport cycle.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4151877/" 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/PMC4151877/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Jonas Y -- Yang, Janet G -- Zhitnitsky, Daniel -- Lewinson, Oded -- Rees, Douglas C -- GM45162/GM/NIGMS NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- R01 GM045162/GM/NIGMS NIH HHS/ -- R37 GM045162/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1133-6. doi: 10.1126/science.1246489.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Division of Chemistry and Chemical Engineering, Mail Code 114-96, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604198" target="_blank"〉PubMed〈/a〉

    Description: Despite recent advances, the structures of many proteins cannot be determined by electron cryomicroscopy because the individual proteins move during irradiation. This blurs the images so that they cannot be aligned with each other to calculate a three-dimensional density. Much of this movement stems from instabilities in the carbon substrates used to support frozen samples in the microscope. Here we demonstrate a gold specimen support that nearly eliminates substrate motion during irradiation. This increases the subnanometer image contrast such that alpha helices of individual proteins are resolved. With this improvement, we determine the structure of apoferritin, a smooth octahedral shell of alpha-helical subunits that is particularly difficult to solve by electron microscopy. This advance in substrate design will enable the solution of currently intractable protein structures.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4296556/" 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/PMC4296556/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Russo, Christopher J -- Passmore, Lori A -- 261151/European Research Council/International -- MC_U105192715/Medical Research Council/United Kingdom -- U105192715/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1377-80. doi: 10.1126/science.1259530.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Laboratory of Molecular Biology, Francis Crick Avenue, Cambridge CB2 0QH, UK. ; Medical Research Council (MRC) Laboratory of Molecular Biology, Francis Crick Avenue, Cambridge CB2 0QH, UK. passmore@mrc-lmb.cam.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25504723" target="_blank"〉PubMed〈/a〉

    Description: Human mitochondrial ribosomes are highly divergent from all other known ribosomes and are specialized to exclusively translate membrane proteins. They are linked with hereditary mitochondrial diseases and are often the unintended targets of various clinically useful antibiotics. Using single-particle cryogenic electron microscopy, we have determined the structure of its large subunit to 3.4 angstrom resolution, revealing 48 proteins, 21 of which are specific to mitochondria. The structure unveils an adaptation of the exit tunnel for hydrophobic nascent peptides, extensive remodeling of the central protuberance, including recruitment of mitochondrial valine transfer RNA (tRNA(Val)) to play an integral structural role, and changes in the tRNA binding sites related to the unusual characteristics of mitochondrial tRNAs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4246062/" 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/PMC4246062/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, Alan -- Amunts, Alexey -- Bai, Xiao-chen -- Sugimoto, Yoichiro -- Edwards, Patricia C -- Murshudov, Garib -- Scheres, Sjors H W -- Ramakrishnan, V -- 096570/Wellcome Trust/United Kingdom -- MC_U105184332/Medical Research Council/United Kingdom -- MC_UP_A025_1012/Medical Research Council/United Kingdom -- MC_UP_A025_1013/Medical Research Council/United Kingdom -- WT096570/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Nov 7;346(6210):718-22. doi: 10.1126/science.1258026.

    Description: Phosphatidylinositol 4-kinases (PI4Ks) and small guanosine triphosphatases (GTPases) are essential for processes that require expansion and remodeling of phosphatidylinositol 4-phosphate (PI4P)-containing membranes, including cytokinesis, intracellular development of malarial pathogens, and replication of a wide range of RNA viruses. However, the structural basis for coordination of PI4K, GTPases, and their effectors is unknown. Here, we describe structures of PI4Kbeta (PI4KIIIbeta) bound to the small GTPase Rab11a without and with the Rab11 effector protein FIP3. The Rab11-PI4KIIIbeta interface is distinct compared with known structures of Rab complexes and does not involve switch regions used by GTPase effectors. Our data provide a mechanism for how PI4KIIIbeta coordinates Rab11 and its effectors on PI4P-enriched membranes and also provide strategies for the design of specific inhibitors that could potentially target plasmodial PI4KIIIbeta to combat malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4046302/" 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/PMC4046302/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burke, John E -- Inglis, Alison J -- Perisic, Olga -- Masson, Glenn R -- McLaughlin, Stephen H -- Rutaganira, Florentine -- Shokat, Kevan M -- Williams, Roger L -- MC_U105184308/Medical Research Council/United Kingdom -- PG/11/109/29247/British Heart Foundation/United Kingdom -- PG11/109/29247/British Heart Foundation/United Kingdom -- R01AI099245/AI/NIAID NIH HHS/ -- T32 GM064337/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):1035-8. doi: 10.1126/science.1253397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. jeburke@uvic.ca rlw@mrc-lmb.cam.ac.uk. ; Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. ; Howard Hughes Medical Institute and Department of Cellular and Molecular Pharmacology, University of California, San Francisco (UCSF), San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24876499" target="_blank"〉PubMed〈/a〉

    Description: Molecular chaperones prevent aggregation and misfolding of proteins, but scarcity of structural data has impeded an understanding of the recognition and antiaggregation mechanisms. We report the solution structure, dynamics, and energetics of three trigger factor (TF) chaperone molecules in complex with alkaline phosphatase (PhoA) captured in the unfolded state. Our data show that TF uses multiple sites to bind to several regions of the PhoA substrate protein primarily through hydrophobic contacts. Nuclear magnetic resonance (NMR) relaxation experiments show that TF interacts with PhoA in a highly dynamic fashion, but as the number and length of the PhoA regions engaged by TF increase, a more stable complex gradually emerges. Multivalent binding keeps the substrate protein in an extended, unfolded conformation. The results show how molecular chaperones recognize unfolded polypeptides and, by acting as unfoldases and holdases, prevent the aggregation and premature (mis)folding of unfolded proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4070327/" 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/PMC4070327/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saio, Tomohide -- Guan, Xiao -- Rossi, Paolo -- Economou, Anastassios -- Kalodimos, Charalampos G -- GM073854/GM/NIGMS NIH HHS/ -- R01 GM073854/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 May 9;344(6184):1250494. doi: 10.1126/science.1250494.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Integrative Proteomics Research and Department of Chemistry and Chemical Biology, Rutgers University, Piscataway, NJ 08854, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24812405" target="_blank"〉PubMed〈/a〉

    Description: River networks evolve as migrating drainage divides reshape river basins and change network topology by capture of river channels. We demonstrate that a characteristic metric of river network geometry gauges the horizontal motion of drainage divides. Assessing this metric throughout a landscape maps the dynamic states of entire river networks, revealing diverse conditions: Drainage divides in the Loess Plateau of China appear stationary; the young topography of Taiwan has migrating divides driving adjustment of major basins; and rivers draining the ancient landscape of the southeastern United States are reorganizing in response to escarpment retreat and coastal advance. The ability to measure the dynamic reorganization of river basins presents opportunities to examine landscape-scale interactions among tectonics, erosion, and ecology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willett, Sean D -- McCoy, Scott W -- Perron, J Taylor -- Goren, Liran -- Chen, Chia-Yu -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1248765. doi: 10.1126/science.1248765.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geological Institute, Swiss Federal Institute of Technology, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604204" target="_blank"〉PubMed〈/a〉

    Description: In certain human cancers, the expression of critical oncogenes is driven from large regulatory elements, called super-enhancers, that recruit much of the cell's transcriptional apparatus and are defined by extensive acetylation of histone H3 lysine 27 (H3K27ac). In a subset of T-cell acute lymphoblastic leukemia (T-ALL) cases, we found that heterozygous somatic mutations are acquired that introduce binding motifs for the MYB transcription factor in a precise noncoding site, which creates a super-enhancer upstream of the TAL1 oncogene. MYB binds to this new site and recruits its H3K27 acetylase-binding partner CBP, as well as core components of a major leukemogenic transcriptional complex that contains RUNX1, GATA-3, and TAL1 itself. Additionally, most endogenous super-enhancers found in T-ALL cells are occupied by MYB and CBP, which suggests a general role for MYB in super-enhancer initiation. Thus, this study identifies a genetic mechanism responsible for the generation of oncogenic super-enhancers in malignant cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4720521/" 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/PMC4720521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mansour, Marc R -- Abraham, Brian J -- Anders, Lars -- Berezovskaya, Alla -- Gutierrez, Alejandro -- Durbin, Adam D -- Etchin, Julia -- Lawton, Lee -- Sallan, Stephen E -- Silverman, Lewis B -- Loh, Mignon L -- Hunger, Stephen P -- Sanda, Takaomi -- Young, Richard A -- Look, A Thomas -- 1R01CA176746-01/CA/NCI NIH HHS/ -- 5P01CA109901-08/CA/NCI NIH HHS/ -- 5P01CA68484/CA/NCI NIH HHS/ -- CA114766/CA/NCI NIH HHS/ -- CA120215/CA/NCI NIH HHS/ -- CA167124/CA/NCI NIH HHS/ -- CA29139/CA/NCI NIH HHS/ -- CA30969/CA/NCI NIH HHS/ -- CA98413/CA/NCI NIH HHS/ -- CA98543/CA/NCI NIH HHS/ -- P01 CA109901/CA/NCI NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- R01 HG002668/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1373-7. doi: 10.1126/science.1259037.

    Description: The signal recognition particle (SRP) is central to membrane protein targeting; SRP RNA is essential for SRP assembly, elongation arrest, and activation of SRP guanosine triphosphatases. In eukaryotes, SRP function relies on the SRP68-SRP72 heterodimer. We present the crystal structures of the RNA-binding domain of SRP68 (SRP68-RBD) alone and in complex with SRP RNA and SRP19. SRP68-RBD is a tetratricopeptide-like module that binds to a RNA three-way junction, bends the RNA, and inserts an alpha-helical arginine-rich motif (ARM) into the major groove. The ARM opens the conserved 5f RNA loop, which in ribosome-bound SRP establishes a contact to ribosomal RNA. Our data provide the structural basis for eukaryote-specific, SRP68-driven RNA remodeling required for protein translocation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grotwinkel, Jan Timo -- Wild, Klemens -- Segnitz, Bernd -- Sinning, Irmgard -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):101-4. doi: 10.1126/science.1249094.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Heidelberg University Biochemistry Center (BZH), INF 328, D-69120 Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24700861" target="_blank"〉PubMed〈/a〉

    Description: N-Methyl-D-aspartate (NMDA) receptors belong to the family of ionotropic glutamate receptors, which mediate most excitatory synaptic transmission in mammalian brains. Calcium permeation triggered by activation of NMDA receptors is the pivotal event for initiation of neuronal plasticity. Here, we show the crystal structure of the intact heterotetrameric GluN1-GluN2B NMDA receptor ion channel at 4 angstroms. The NMDA receptors are arranged as a dimer of GluN1-GluN2B heterodimers with the twofold symmetry axis running through the entire molecule composed of an amino terminal domain (ATD), a ligand-binding domain (LBD), and a transmembrane domain (TMD). The ATD and LBD are much more highly packed in the NMDA receptors than non-NMDA receptors, which may explain why ATD regulates ion channel activity in NMDA receptors but not in non-NMDA receptors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4113085/" 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/PMC4113085/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karakas, Erkan -- Furukawa, Hiro -- MH085926/MH/NIMH NIH HHS/ -- R01 GM105730/GM/NIGMS NIH HHS/ -- R01 MH085926/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):992-7. doi: 10.1126/science.1251915.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, W.

    Description: Potassium channels selectively conduct K(+) ions across cellular membranes with extraordinary efficiency. Their selectivity filter exhibits four binding sites with approximately equal electron density in crystal structures with high K(+) concentrations, previously thought to reflect a superposition of alternating ion- and water-occupied states. Consequently, cotranslocation of ions with water has become a widely accepted ion conduction mechanism for potassium channels. By analyzing more than 1300 permeation events from molecular dynamics simulations at physiological voltages, we observed instead that permeation occurs via ion-ion contacts between neighboring K(+) ions. Coulomb repulsion between adjacent ions is found to be the key to high-efficiency K(+) conduction. Crystallographic data are consistent with directly neighboring K(+) ions in the selectivity filter, and our model offers an intuitive explanation for the high throughput rates of K(+) channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kopfer, David A -- Song, Chen -- Gruene, Tim -- Sheldrick, George M -- Zachariae, Ulrich -- de Groot, Bert L -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):352-5. doi: 10.1126/science.1254840.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biomolecular Dynamics Group, Max Planck Institute for Biophysical Chemistry, 37077 Gottingen, Germany. ; Department of Biochemistry, University of Oxford, Oxford OX1 3QU, UK. sc3210@gmail.com u.zachariae@dundee.ac.uk bgroot@gwdg.de. ; Department of Structural Chemistry, University of Gottingen, 37077 Gottingen, Germany. ; School of Engineering, Physics and Mathematics, University of Dundee, Dundee DD1 4HN, UK.

    Description: Evolution and design of protein complexes are almost always viewed through the lens of amino acid mutations at protein interfaces. We showed previously that residues not involved in the physical interaction between proteins make important contributions to oligomerization by acting indirectly or allosterically. In this work, we sought to investigate the mechanism by which allosteric mutations act, using the example of the PyrR family of pyrimidine operon attenuators. In this family, a perfectly sequence-conserved helix that forms a tetrameric interface is exposed as solvent-accessible surface in dimeric orthologs. This means that mutations must be acting from a distance to destabilize the interface. We identified 11 key mutations controlling oligomeric state, all distant from the interfaces and outside ligand-binding pockets. Finally, we show that the key mutations introduce conformational changes equivalent to the conformational shift between the free versus nucleotide-bound conformations of the proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4337988/" 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/PMC4337988/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perica, Tina -- Kondo, Yasushi -- Tiwari, Sandhya P -- McLaughlin, Stephen H -- Kemplen, Katherine R -- Zhang, Xiuwei -- Steward, Annette -- Reuter, Nathalie -- Clarke, Jane -- Teichmann, Sarah A -- 095195/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Dec 19;346(6216):1254346. doi: 10.1126/science.1254346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Bioinformatics Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SD, UK.

    Description: Coupled translocation of messenger RNA and transfer RNA (tRNA) through the ribosome, a process catalyzed by elongation factor EF-G, is a crucial step in protein synthesis. The crystal structure of a bacterial translocation complex describes the binding states of two tRNAs trapped in mid-translocation. The deacylated P-site tRNA has moved into a partly translocated pe/E chimeric hybrid state. The anticodon stem-loop of the A-site tRNA is captured in transition toward the 30S P site, while its 3' acceptor end contacts both the A and P loops of the 50S subunit, forming an ap/ap chimeric hybrid state. The structure shows how features of ribosomal RNA rearrange to hand off the A-site tRNA to the P site, revealing an active role for ribosomal RNA in the translocation process.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4242719/" 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/PMC4242719/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Jie -- Lancaster, Laura -- Donohue, John Paul -- Noller, Harry F -- GM-17129/GM/NIGMS NIH HHS/ -- GM59140/GM/NIGMS NIH HHS/ -- R01 GM017129/GM/NIGMS NIH HHS/ -- R01 GM059140/GM/NIGMS NIH HHS/ -- R01 GM105404/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Sep 5;345(6201):1188-91. doi: 10.1126/science.1255030.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Biology of RNA and Department of Molecular, Cell and Developmental Biology, University of California at Santa Cruz, Santa Cruz, CA 95064, USA. ; Center for Molecular Biology of RNA and Department of Molecular, Cell and Developmental Biology, University of California at Santa Cruz, Santa Cruz, CA 95064, USA. harry@nuvolari.ucsc.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25190797" target="_blank"〉PubMed〈/a〉

    Description: Tight junctions are cell-cell adhesion structures in epithelial cell sheets that surround organ compartments in multicellular organisms and regulate the permeation of ions through the intercellular space. Claudins are the major constituents of tight junctions and form strands that mediate cell adhesion and function as paracellular barriers. We report the structure of mammalian claudin-15 at a resolution of 2.4 angstroms. The structure reveals a characteristic beta-sheet fold comprising two extracellular segments, which is anchored to a transmembrane four-helix bundle by a consensus motif. Our analyses suggest potential paracellular pathways with distinctive charges on the extracellular surface, providing insight into the molecular basis of ion homeostasis across tight junctions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, Hiroshi -- Nishizawa, Tomohiro -- Tani, Kazutoshi -- Yamazaki, Yuji -- Tamura, Atsushi -- Ishitani, Ryuichiro -- Dohmae, Naoshi -- Tsukita, Sachiko -- Nureki, Osamu -- Fujiyoshi, Yoshinori -- New York, N.Y. -- Science. 2014 Apr 18;344(6181):304-7. doi: 10.1126/science.1248571.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cellular and Structural Physiology Institute, Nagoya University, Chikusa, Nagoya 464-8601, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24744376" target="_blank"〉PubMed〈/a〉

    Description: The yeast mitochondrial ABC transporter Atm1, in concert with glutathione, functions in the export of a substrate required for cytosolic-nuclear iron-sulfur protein biogenesis and cellular iron regulation. Defects in the human ortholog ABCB7 cause the sideroblastic anemia XLSA/A. Here, we report the crystal structures of free and glutathione-bound Atm1 in inward-facing, open conformations at 3.06- and 3.38-angstrom resolution, respectively. The glutathione binding site includes a residue mutated in XLSA/A and is located close to the inner membrane surface in a large cavity. The two nucleotide-free adenosine 5'-triphosphate binding domains do not interact yet are kept in close vicinity through tight interaction of the two C-terminal alpha-helices of the Atm1 dimer. The resulting protein stabilization may be a common structural feature of all ABC exporters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srinivasan, Vasundara -- Pierik, Antonio J -- Lill, Roland -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1137-40. doi: 10.1126/science.1246729.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Zytobiologie, Philipps-Universitat Marburg, Robert-Koch-Strasse 6, 35032 Marburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604199" target="_blank"〉PubMed〈/a〉

    Description: Human bestrophin-1 (hBest1) is a calcium-activated chloride channel from the retinal pigment epithelium, where mutations are associated with vitelliform macular degeneration, or Best disease. We describe the structure of a bacterial homolog (KpBest) of hBest1 and functional characterizations of both channels. KpBest is a pentamer that forms a five-helix transmembrane pore, closed by three rings of conserved hydrophobic residues, and has a cytoplasmic cavern with a restricted exit. From electrophysiological analysis of structure-inspired mutations in KpBest and hBest1, we find a sensitive control of ion selectivity in the bestrophins, including reversal of anion/cation selectivity, and dramatic activation by mutations at the cytoplasmic exit. A homology model of hBest1 shows the locations of disease-causing mutations and suggests possible roles in regulation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4341822/" 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/PMC4341822/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Tingting -- Liu, Qun -- Kloss, Brian -- Bruni, Renato -- Kalathur, Ravi C -- Guo, Youzhong -- Kloppmann, Edda -- Rost, Burkhard -- Colecraft, Henry M -- Hendrickson, Wayne A -- GM095315/GM/NIGMS NIH HHS/ -- GM107462/GM/NIGMS NIH HHS/ -- R01 GM107462/GM/NIGMS NIH HHS/ -- U54 GM075026/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):355-9. doi: 10.1126/science.1259723.

    Description: In 2008, Oregon initiated a limited expansion of a Medicaid program for uninsured, low-income adults, drawing names from a waiting list by lottery. This lottery created a rare opportunity to study the effects of Medicaid coverage by using a randomized controlled design. By using the randomization provided by the lottery and emergency-department records from Portland-area hospitals, we studied the emergency department use of about 25,000 lottery participants over about 18 months after the lottery. We found that Medicaid coverage significantly increases overall emergency use by 0.41 visits per person, or 40% relative to an average of 1.02 visits per person in the control group. We found increases in emergency-department visits across a broad range of types of visits, conditions, and subgroups, including increases in visits for conditions that may be most readily treatable in primary care settings.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3955206/" 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/PMC3955206/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taubman, Sarah L -- Allen, Heidi L -- Wright, Bill J -- Baicker, Katherine -- Finkelstein, Amy N -- P30 AG012810/AG/NIA NIH HHS/ -- P30AG012810/AG/NIA NIH HHS/ -- R01 AG034151/AG/NIA NIH HHS/ -- R01AG0345151/AG/NIA NIH HHS/ -- RC2 AG036631/AG/NIA NIH HHS/ -- RC2AGO36631/RC/CCR NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 17;343(6168):263-8. doi: 10.1126/science.1246183.

    Description: Serial femtosecond crystallography using ultrashort pulses from x-ray free electron lasers (XFELs) enables studies of the light-triggered dynamics of biomolecules. We used microcrystals of photoactive yellow protein (a bacterial blue light photoreceptor) as a model system and obtained high-resolution, time-resolved difference electron density maps of excellent quality with strong features; these allowed the determination of structures of reaction intermediates to a resolution of 1.6 angstroms. Our results open the way to the study of reversible and nonreversible biological reactions on time scales as short as femtoseconds under conditions that maximize the extent of reaction initiation throughout the crystal.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4361027/" 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/PMC4361027/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tenboer, Jason -- Basu, Shibom -- Zatsepin, Nadia -- Pande, Kanupriya -- Milathianaki, Despina -- Frank, Matthias -- Hunter, Mark -- Boutet, Sebastien -- Williams, Garth J -- Koglin, Jason E -- Oberthuer, Dominik -- Heymann, Michael -- Kupitz, Christopher -- Conrad, Chelsie -- Coe, Jesse -- Roy-Chowdhury, Shatabdi -- Weierstall, Uwe -- James, Daniel -- Wang, Dingjie -- Grant, Thomas -- Barty, Anton -- Yefanov, Oleksandr -- Scales, Jennifer -- Gati, Cornelius -- Seuring, Carolin -- Srajer, Vukica -- Henning, Robert -- Schwander, Peter -- Fromme, Raimund -- Ourmazd, Abbas -- Moffat, Keith -- Van Thor, Jasper J -- Spence, John C H -- Fromme, Petra -- Chapman, Henry N -- Schmidt, Marius -- P41 GM103543/GM/NIGMS NIH HHS/ -- R01GM095583/GM/NIGMS NIH HHS/ -- R24 GM111072/GM/NIGMS NIH HHS/ -- R24GM111072/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1242-6. doi: 10.1126/science.1259357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physics Department, University of Wisconsin, Milwaukee, WI 53211, USA. ; Department of Chemistry and Biochemistry, Arizona State University, Tempe, AZ 85287, USA. ; Department of Physics, Arizona State University, Tempe, AZ 85287, USA. ; Linac Coherent Light Source, SLAC National Accelerator Laboratory, Sand Hill Road, Menlo Park, CA 94025, USA. ; Lawrence Livermore National Laboratory, Livermore, CA 94550, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany. ; Center for Free Electron Laser Science, Deutsches Elektronen Synchrotron DESY, Notkestrasse 85, 22607 Hamburg, Germany. ; Hauptman-Woodward Institute, State University of New York at Buffalo, 700 Ellicott Street, Buffalo, NY 14203, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany.

    Description: Complement activation by antibodies bound to pathogens, tumors, and self antigens is a critical feature of natural immune defense, a number of disease processes, and immunotherapies. How antibodies activate the complement cascade, however, is poorly understood. We found that specific noncovalent interactions between Fc segments of immunoglobulin G (IgG) antibodies resulted in the formation of ordered antibody hexamers after antigen binding on cells. These hexamers recruited and activated C1, the first component of complement, thereby triggering the complement cascade. The interactions between neighboring Fc segments could be manipulated to block, reconstitute, and enhance complement activation and killing of target cells, using all four human IgG subclasses. We offer a general model for understanding antibody-mediated complement activation and the design of antibody therapeutics with enhanced efficacy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4250092/" 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/PMC4250092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diebolder, Christoph A -- Beurskens, Frank J -- de Jong, Rob N -- Koning, Roman I -- Strumane, Kristin -- Lindorfer, Margaret A -- Voorhorst, Marleen -- Ugurlar, Deniz -- Rosati, Sara -- Heck, Albert J R -- van de Winkel, Jan G J -- Wilson, Ian A -- Koster, Abraham J -- Taylor, Ronald P -- Saphire, Erica Ollmann -- Burton, Dennis R -- Schuurman, Janine -- Gros, Piet -- Parren, Paul W H I -- AI055332/AI/NIAID NIH HHS/ -- AI084817/AI/NIAID NIH HHS/ -- R01 AI055332/AI/NIAID NIH HHS/ -- R37 AI055332/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 14;343(6176):1260-3. doi: 10.1126/science.1248943.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Crystal and Structural Chemistry, Bijvoet Center for Biomolecular Research, Department of Chemistry, Faculty of Science, Utrecht University, 3584 CH Utrecht, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24626930" target="_blank"〉PubMed〈/a〉

    Description: With the recent advances in ultrabright electron and x-ray sources, it is now possible to extend crystallography to the femtosecond time domain to literally light up atomic motions involved in the primary processes governing structural transitions. This review chronicles the development of brighter and brighter electron and x-ray sources that have enabled atomic resolution to structural dynamics for increasingly complex systems. The primary focus is on achieving sufficient brightness using pump-probe protocols to resolve the far-from-equilibrium motions directing chemical processes that in general lead to irreversible changes in samples. Given the central importance of structural transitions to conceptualizing chemistry, this emerging field has the potential to significantly improve our understanding of chemistry and its connection to driving biological processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, R J Dwayne -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1108-16. doi: 10.1126/science.1248488.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Atomically Resolved Dynamics Division, The Max Planck Institute for the Structure and Dynamics of Matter, The Hamburg Centre for Ultrafast Imaging, Luruper Chaussee 149, Hamburg 22761, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604195" target="_blank"〉PubMed〈/a〉
