    Description: Meiotic recombination events cluster into narrow segments of the genome, defined as hotspots. Here, we demonstrate that a major player for hotspot specification is the Prdm9 gene. First, two mouse strains that differ in hotspot usage are polymorphic for the zinc finger DNA binding array of PRDM9. Second, the human consensus PRDM9 allele is predicted to recognize the 13-mer motif enriched at human hotspots; this DNA binding specificity is verified by in vitro studies. Third, allelic variants of PRDM9 zinc fingers are significantly associated with variability in genome-wide hotspot usage among humans. Our results provide a molecular basis for the distribution of meiotic recombination in mammals, in which the binding of PRDM9 to specific DNA sequences targets the initiation of recombination at specific locations in the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295902/" 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/PMC4295902/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baudat, F -- Buard, J -- Grey, C -- Fledel-Alon, A -- Ober, C -- Przeworski, M -- Coop, G -- de Massy, B -- 03S1/PHS HHS/ -- GM83098/GM/NIGMS NIH HHS/ -- HD21244/HD/NICHD NIH HHS/ -- HL085197/HL/NHLBI NIH HHS/ -- R01 GM083098/GM/NIGMS NIH HHS/ -- R01 HD021244/HD/NICHD NIH HHS/ -- R01 HL085197/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):836-40. doi: 10.1126/science.1183439.

    Description: CD4(+)Foxp3(+) regulatory T (T(reg)) cells are important for maintaining immune tolerance. Understanding the molecular mechanism that regulates T(reg) differentiation will facilitate the development of effective therapeutic strategies against autoimmune diseases. We report here that the SUMO E3 ligase PIAS1 restricts the differentiation of natural T(reg) cells by maintaining a repressive chromatin state of the Foxp3 promoter. PIAS1 acts by binding to the Foxp3 promoter to recruit DNA methyltransferases and heterochromatin protein 1 for epigenetic modifications. Pias1 deletion caused promoter demethylation, reduced histone H3 methylation at Lys(9), and enhanced promoter accessibility. Consistently, Pias1(-/-) mice displayed an increased natural T(reg) cell population and were resistant to the development of experimental autoimmune encephalomyelitis. Our studies have identified an epigenetic mechanism that negatively regulates the differentiation of natural T(reg) cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3043201/" 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/PMC3043201/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Bin -- Tahk, Samuel -- Yee, Kathleen M -- Fan, Guoping -- Shuai, Ke -- K01 AR52717-01/AR/NIAMS NIH HHS/ -- R01 AI063286/AI/NIAID NIH HHS/ -- R01 AI063286-05/AI/NIAID NIH HHS/ -- R01 GM085797/GM/NIGMS NIH HHS/ -- R01 GM085797-03/GM/NIGMS NIH HHS/ -- R01AI063286/AI/NIAID NIH HHS/ -- R01GM085797/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 22;330(6003):521-5. doi: 10.1126/science.1193787.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology-Oncology, Department of Medicine, 11-934 Factor Building, 10833 Le Conte Avenue, University of California, Los Angeles, Los Angeles, CA 90095, USA. bliu@ucla.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20966256" target="_blank"〉PubMed〈/a〉

    Description: The class Ib ribonucleotide reductase of Escherichia coli can initiate reduction of nucleotides to deoxynucleotides with either a Mn(III)2-tyrosyl radical (Y*) or a Fe(III)2-Y* cofactor in the NrdF subunit. Whereas Fe(III)2-Y* can self-assemble from Fe(II)2-NrdF and O2, activation of Mn(II)2-NrdF requires a reduced flavoprotein, NrdI, proposed to form the oxidant for cofactor assembly by reduction of O2. The crystal structures reported here of E. coli Mn(II)2-NrdF and Fe(II)2-NrdF reveal different coordination environments, suggesting distinct initial binding sites for the oxidants during cofactor activation. In the structures of Mn(II)2-NrdF in complex with reduced and oxidized NrdI, a continuous channel connects the NrdI flavin cofactor to the NrdF Mn(II)2 active site. Crystallographic detection of a putative peroxide in this channel supports the proposed mechanism of Mn(III)2-Y* cofactor assembly.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3020666/" 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/PMC3020666/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boal, Amie K -- Cotruvo, Joseph A Jr -- Stubbe, JoAnne -- Rosenzweig, Amy C -- GM58518/GM/NIGMS NIH HHS/ -- GM81393/GM/NIGMS NIH HHS/ -- R01 GM058518/GM/NIGMS NIH HHS/ -- R01 GM058518-13/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1526-30. doi: 10.1126/science.1190187.

    Description: Transcriptional positive-feedback loops are widely associated with bistability, characterized by two stable expression states that allow cells to respond to analog signals in a digital manner. Using a synthetic system in budding yeast, we show that positive feedback involving a promoter with multiple transcription factor (TF) binding sites can induce a steady-state bimodal response without cooperative binding of the TF. Deterministic models of this system do not predict bistability. Rather, the bimodal response requires a short-lived TF and stochastic fluctuations in the TF's expression. Multiple binding sites provide these fluctuations. Because many promoters possess multiple binding sites and many TFs are unstable, positive-feedback loops in gene regulatory networks may exhibit bimodal responses, but not necessarily because of deterministic bistability, as is commonly thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉To, Tsz-Leung -- Maheshri, Narendra -- New York, N.Y. -- Science. 2010 Feb 26;327(5969):1142-5. doi: 10.1126/science.1178962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20185727" target="_blank"〉PubMed〈/a〉

    Description: Differences in gene expression may play a major role in speciation and phenotypic diversity. We examined genome-wide differences in transcription factor (TF) binding in several humans and a single chimpanzee by using chromatin immunoprecipitation followed by sequencing. The binding sites of RNA polymerase II (PolII) and a key regulator of immune responses, nuclear factor kappaB (p65), were mapped in 10 lymphoblastoid cell lines, and 25 and 7.5% of the respective binding regions were found to differ between individuals. Binding differences were frequently associated with single-nucleotide polymorphisms and genomic structural variants, and these differences were often correlated with differences in gene expression, suggesting functional consequences of binding variation. Furthermore, comparing PolII binding between humans and chimpanzee suggests extensive divergence in TF binding. Our results indicate that many differences in individuals and species occur at the level of TF binding, and they provide insight into the genetic events responsible for these differences.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938768/" 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/PMC2938768/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasowski, Maya -- Grubert, Fabian -- Heffelfinger, Christopher -- Hariharan, Manoj -- Asabere, Akwasi -- Waszak, Sebastian M -- Habegger, Lukas -- Rozowsky, Joel -- Shi, Minyi -- Urban, Alexander E -- Hong, Mi-Young -- Karczewski, Konrad J -- Huber, Wolfgang -- Weissman, Sherman M -- Gerstein, Mark B -- Korbel, Jan O -- Snyder, Michael -- R01 CA077808/CA/NCI NIH HHS/ -- R01 CA077808-09/CA/NCI NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- T32 GM007205-34/GM/NIGMS NIH HHS/ -- T32GM07205/GM/NIGMS NIH HHS/ -- U54 HG004558/HG/NHGRI NIH HHS/ -- U54 HG004558-04/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):232-5. doi: 10.1126/science.1183621.

    Description: Integrins mediate cell adhesion to the extracellular matrix and transmit signals within the cell that stimulate cell spreading, retraction, migration, and proliferation. The mechanism of integrin outside-in signaling has been unclear. We found that the heterotrimeric guanine nucleotide-binding protein (G protein) Galpha13 directly bound to the integrin beta3 cytoplasmic domain and that Galpha13-integrin interaction was promoted by ligand binding to the integrin alphaIIbbeta3 and by guanosine triphosphate (GTP) loading of Galpha13. Interference of Galpha13 expression or a myristoylated fragment of Galpha13 that inhibited interaction of alphaIIbbeta3 with Galpha13 diminished activation of protein kinase c-Src and stimulated the small guanosine triphosphatase RhoA, consequently inhibiting cell spreading and accelerating cell retraction. We conclude that integrins are noncanonical Galpha13-coupled receptors that provide a mechanism for dynamic regulation of RhoA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2842917/" 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/PMC2842917/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gong, Haixia -- Shen, Bo -- Flevaris, Panagiotis -- Chow, Christina -- Lam, Stephen C-T -- Voyno-Yasenetskaya, Tatyana A -- Kozasa, Tohru -- Du, Xiaoping -- GM061454/GM/NIGMS NIH HHS/ -- GM074001/GM/NIGMS NIH HHS/ -- HL062350/HL/NHLBI NIH HHS/ -- HL068819/HL/NHLBI NIH HHS/ -- HL080264/HL/NHLBI NIH HHS/ -- R01 GM061454/GM/NIGMS NIH HHS/ -- R01 GM061454-09/GM/NIGMS NIH HHS/ -- R01 GM074001/GM/NIGMS NIH HHS/ -- R01 GM074001-02/GM/NIGMS NIH HHS/ -- R01 HL062350/HL/NHLBI NIH HHS/ -- R01 HL062350-09/HL/NHLBI NIH HHS/ -- R01 HL068819/HL/NHLBI NIH HHS/ -- R01 HL068819-08/HL/NHLBI NIH HHS/ -- R01 HL080264/HL/NHLBI NIH HHS/ -- R01 HL080264-04/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):340-3. doi: 10.1126/science.1174779.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Illinois at Chicago, 835 South Wolcott Avenue, Room E403, Chicago, IL 60612, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075254" target="_blank"〉PubMed〈/a〉

    Description: Efficient enzymatic conversion of crystalline polysaccharides is crucial for an economically and environmentally sustainable bioeconomy but remains unfavorably inefficient. We describe an enzyme that acts on the surface of crystalline chitin, where it introduces chain breaks and generates oxidized chain ends, thus promoting further degradation by chitinases. This enzymatic activity was discovered and further characterized by using mass spectrometry and chromatographic separation methods to detect oxidized products generated in the absence or presence of H(2)(18)O or (18)O(2). There are strong indications that similar enzymes exist that work on cellulose. Our findings not only demonstrate the existence of a hitherto unknown enzyme activity but also provide new avenues toward more efficient enzymatic conversion of biomass.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vaaje-Kolstad, Gustav -- Westereng, Bjorge -- Horn, Svein J -- Liu, Zhanliang -- Zhai, Hong -- Sorlie, Morten -- Eijsink, Vincent G H -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):219-22. doi: 10.1126/science.1192231.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Biotechnology and Food Science, Norwegian University of Life Sciences, Post Office Box 5003, 1432 As, Norway.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929773" target="_blank"〉PubMed〈/a〉

    Description: Microorganisms can switch from a planktonic, free-swimming life-style to a sessile, colonial state, called a biofilm, which confers resistance to environmental stress. Conversion between the motile and biofilm life-styles has been attributed to increased levels of the prokaryotic second messenger cyclic di-guanosine monophosphate (c-di-GMP), yet the signaling mechanisms mediating such a global switch are poorly understood. Here we show that the transcriptional regulator VpsT from Vibrio cholerae directly senses c-di-GMP to inversely control extracellular matrix production and motility, which identifies VpsT as a master regulator for biofilm formation. Rather than being regulated by phosphorylation, VpsT undergoes a change in oligomerization on c-di-GMP binding.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2828054/" 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/PMC2828054/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krasteva, Petya V -- Fong, Jiunn C N -- Shikuma, Nicholas J -- Beyhan, Sinem -- Navarro, Marcos V A S -- Yildiz, Fitnat H -- Sondermann, Holger -- 1R01GM081373/GM/NIGMS NIH HHS/ -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 AI055987/AI/NIAID NIH HHS/ -- R01 AI055987-06A1/AI/NIAID NIH HHS/ -- R01 GM081373/GM/NIGMS NIH HHS/ -- R01 GM081373-03/GM/NIGMS NIH HHS/ -- R01AI055987/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):866-8. doi: 10.1126/science.1181185.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Medicine, College of Veterinary Medicine, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20150502" target="_blank"〉PubMed〈/a〉

    Description: The structure of the sodium-benzylhydantoin transport protein Mhp1 from Microbacterium liquefaciens comprises a five-helix inverted repeat, which is widespread among secondary transporters. Here, we report the crystal structure of an inward-facing conformation of Mhp1 at 3.8 angstroms resolution, complementing its previously described structures in outward-facing and occluded states. From analyses of the three structures and molecular dynamics simulations, we propose a mechanism for the transport cycle in Mhp1. Switching from the outward- to the inward-facing state, to effect the inward release of sodium and benzylhydantoin, is primarily achieved by a rigid body movement of transmembrane helices 3, 4, 8, and 9 relative to the rest of the protein. This forms the basis of an alternating access mechanism applicable to many transporters of this emerging superfamily.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2885435/" 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/PMC2885435/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shimamura, Tatsuro -- Weyand, Simone -- Beckstein, Oliver -- Rutherford, Nicholas G -- Hadden, Jonathan M -- Sharples, David -- Sansom, Mark S P -- Iwata, So -- Henderson, Peter J F -- Cameron, Alexander D -- 062164/Z/00/Z/Wellcome Trust/United Kingdom -- 079209/Wellcome Trust/United Kingdom -- BB/C51725/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G020043/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G023425/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/14418/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):470-3. doi: 10.1126/science.1186303.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Biosciences, Membrane Protein Crystallography Group, Imperial College, London SW7 2AZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413494" target="_blank"〉PubMed〈/a〉

    Description: T cells transformed by Herpesvirus saimiri express seven viral U-rich noncoding RNAs of unknown function called HSURs. We noted that conserved sequences in HSURs 1 and 2 constitute potential binding sites for three host-cell microRNAs (miRNAs). Coimmunoprecipitation experiments confirmed that HSURs 1 and 2 interact with the predicted miRNAs in virally transformed T cells. The abundance of one of these miRNAs, miR-27, is dramatically lowered in transformed cells, with consequent effects on the expression of miR-27 target genes. Transient knockdown and ectopic expression of HSUR 1 demonstrate that it directs degradation of mature miR-27 in a sequence-specific and binding-dependent manner. This viral strategy illustrates use of a ncRNA to manipulate host-cell gene expression via the miRNA pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3075239/" 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/PMC3075239/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cazalla, Demian -- Yario, Therese -- Steitz, Joan A -- CA16038/CA/NCI NIH HHS/ -- P01 CA016038/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jun 18;328(5985):1563-6. doi: 10.1126/science.1187197.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biophysics and Biochemistry, Howard Hughes Medical Institute, Yale University School of Medicine, Boyer Center for Molecular Medicine, 295 Congress Avenue, New Haven, CT 06536, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20558719" target="_blank"〉PubMed〈/a〉

    Description: Proton-pumping respiratory complex I is one of the largest and most complicated membrane protein complexes. Its function is critical for efficient energy supply in aerobic cells, and malfunctions are implicated in many neurodegenerative disorders. Here, we report an x-ray crystallographic analysis of mitochondrial complex I. The positions of all iron-sulfur clusters relative to the membrane arm were determined in the complete enzyme complex. The ubiquinone reduction site resides close to 30 angstroms above the membrane domain. The arrangement of functional modules suggests conformational coupling of redox chemistry with proton pumping and essentially excludes direct mechanisms. We suggest that a approximately 60-angstrom-long helical transmission element is critical for transducing conformational energy to proton-pumping elements in the distal module of the membrane arm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunte, Carola -- Zickermann, Volker -- Brandt, Ulrich -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):448-51. doi: 10.1126/science.1191046.

    Description: DNA methylation at proximal promoters facilitates lineage restriction by silencing cell type-specific genes. However, euchromatic DNA methylation frequently occurs in regions outside promoters. The functions of such nonproximal promoter DNA methylation are unclear. Here we show that the de novo DNA methyltransferase Dnmt3a is expressed in postnatal neural stem cells (NSCs) and is required for neurogenesis. Genome-wide analysis of postnatal NSCs indicates that Dnmt3a occupies and methylates intergenic regions and gene bodies flanking proximal promoters of a large cohort of transcriptionally permissive genes, many of which encode regulators of neurogenesis. Surprisingly, Dnmt3a-dependent nonproximal promoter methylation promotes expression of these neurogenic genes by functionally antagonizing Polycomb repression. Thus, nonpromoter DNA methylation by Dnmt3a may be used for maintaining active chromatin states of genes critical for development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3539760/" 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/PMC3539760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Hao -- Coskun, Volkan -- Tao, Jifang -- Xie, Wei -- Ge, Weihong -- Yoshikawa, Kazuaki -- Li, En -- Zhang, Yi -- Sun, Yi Eve -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):444-8. doi: 10.1126/science.1190485.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Medical Pharmacology, University of California Los Angeles (UCLA), Los Angeles, CA 90095, USA. haowu7@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20651149" target="_blank"〉PubMed〈/a〉

    Description: Phosphoinositide 3-kinases (PI3Ks) are lipid kinases with diverse roles in health and disease. The primordial PI3K, Vps34, is present in all eukaryotes and has essential roles in autophagy, membrane trafficking, and cell signaling. We solved the crystal structure of Vps34 at 2.9 angstrom resolution, which revealed a constricted adenine-binding pocket, suggesting the reason that specific inhibitors of this class of PI3K have proven elusive. Both the phosphoinositide-binding loop and the carboxyl-terminal helix of Vps34 mediate catalysis on membranes and suppress futile adenosine triphosphatase cycles. Vps34 appears to alternate between a closed cytosolic form and an open form on the membrane. Structures of Vps34 complexes with a series of inhibitors reveal the reason that an autophagy inhibitor preferentially inhibits Vps34 and underpin the development of new potent and specific Vps34 inhibitors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2860105/" 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/PMC2860105/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Simon -- Tavshanjian, Brandon -- Oleksy, Arkadiusz -- Perisic, Olga -- Houseman, Benjamin T -- Shokat, Kevan M -- Williams, Roger L -- MC_U105184308/Medical Research Council/United Kingdom -- U.1051.03.014(78824)/Medical Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1638-42. doi: 10.1126/science.1184429.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Hills Road, Cambridge CB2 0QH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20339072" target="_blank"〉PubMed〈/a〉

    Description: The bacterial flagellar switch that controls the direction of flagellar rotation during chemotaxis has a highly cooperative response. This has previously been understood in terms of the classic two-state, concerted model of allosteric regulation. Here, we used high-resolution optical microscopy to observe switching of single motors and uncover the stochastic multistate nature of the switch. Our observations are in detailed quantitative agreement with a recent general model of allosteric cooperativity that exhibits conformational spread--the stochastic growth and shrinkage of domains of adjacent subunits sharing a particular conformational state. We expect that conformational spread will be important in explaining cooperativity in other large signaling complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bai, Fan -- Branch, Richard W -- Nicolau, Dan V Jr -- Pilizota, Teuta -- Steel, Bradley C -- Maini, Philip K -- Berry, Richard M -- BB/E00458X/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/H01991X/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Feb 5;327(5966):685-9. doi: 10.1126/science.1182105.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Clarendon Laboratory, Department of Physics, University of Oxford, Parks Road, Oxford OX1 3PU, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20133571" target="_blank"〉PubMed〈/a〉

    Description: High-conductance voltage- and Ca2+-activated K+ (BK) channels encode negative feedback regulation of membrane voltage and Ca2+ signaling, playing a central role in numerous physiological processes. We determined the x-ray structure of the human BK Ca2+ gating apparatus at a resolution of 3.0 angstroms and deduced its tetrameric assembly by solving a 6 angstrom resolution structure of a Na+-activated homolog. Two tandem C-terminal regulator of K+ conductance (RCK) domains from each of four channel subunits form a 350-kilodalton gating ring at the intracellular membrane surface. A sequence of aspartic amino acids that is known as the Ca2+ bowl, and is located within the second of the tandem RCK domains, creates four Ca2+ binding sites on the outer perimeter of the gating ring at the "assembly interface" between RCK domains. Functionally important mutations cluster near the Ca2+ bowl, near the "flexible interface" between RCK domains, and on the surface of the gating ring that faces the voltage sensors. The structure suggests that the Ca2+ gating ring, in addition to regulating the pore directly, may also modulate the voltage sensor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3022345/" 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/PMC3022345/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yuan, Peng -- Leonetti, Manuel D -- Pico, Alexander R -- Hsiung, Yichun -- MacKinnon, Roderick -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 GM043949/GM/NIGMS NIH HHS/ -- R01 GM043949-20/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jul 9;329(5988):182-6. doi: 10.1126/science.1190414.

    Description: CLC proteins transport chloride (Cl(-)) ions across cell membranes to control the electrical potential of muscle cells, transfer electrolytes across epithelia, and control the pH and electrolyte composition of intracellular organelles. Some members of this protein family are Cl(-) ion channels, whereas others are secondary active transporters that exchange Cl(-) ions and protons (H(+)) with a 2:1 stoichiometry. We have determined the structure of a eukaryotic CLC transporter at 3.5 angstrom resolution. Cytoplasmic cystathionine beta-synthase (CBS) domains are strategically positioned to regulate the ion-transport pathway, and many disease-causing mutations in human CLCs reside on the CBS-transmembrane interface. Comparison with prokaryotic CLC shows that a gating glutamate residue changes conformation and suggests a basis for 2:1 Cl(-)/H(+) exchange and a simple mechanistic connection between CLC channels and transporters.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3079386/" 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/PMC3079386/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, Liang -- Campbell, Ernest B -- Hsiung, Yichun -- MacKinnon, Roderick -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 GM043949/GM/NIGMS NIH HHS/ -- R01 GM043949-20/GM/NIGMS NIH HHS/ -- R01 GM043949-21/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Oct 29;330(6004):635-41. doi: 10.1126/science.1195230.

    Description: Voltage sensors regulate the conformations of voltage-dependent ion channels and enzymes. Their nearly switchlike response as a function of membrane voltage comes from the movement of positively charged amino acids, arginine or lysine, across the membrane field. We used mutations with natural and unnatural amino acids, electrophysiological recordings, and x-ray crystallography to identify a charge transfer center in voltage sensors that facilitates this movement. This center consists of a rigid cyclic "cap" and two negatively charged amino acids to interact with a positive charge. Specific mutations induce a preference for lysine relative to arginine. By placing lysine at specific locations, the voltage sensor can be stabilized in different conformations, which enables a dissection of voltage sensor movements and their relation to ion channel opening.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2869078/" 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/PMC2869078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tao, Xiao -- Lee, Alice -- Limapichat, Walrati -- Dougherty, Dennis A -- MacKinnon, Roderick -- GM43949/GM/NIGMS NIH HHS/ -- NS 34407/NS/NINDS NIH HHS/ -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 GM043949/GM/NIGMS NIH HHS/ -- R01 GM043949-20/GM/NIGMS NIH HHS/ -- R37 NS034407/NS/NINDS NIH HHS/ -- R37 NS034407-15/NS/NINDS NIH HHS/ -- R37 NS034407-15S1/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 2;328(5974):67-73. doi: 10.1126/science.1185954.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Neurobiology and Biophysics, Rockefeller University, Howard Hughes Medical Institute, 1230 York Avenue, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20360102" target="_blank"〉PubMed〈/a〉

    Description: To gain insight into how genomic information is translated into cellular and developmental programs, the Drosophila model organism Encyclopedia of DNA Elements (modENCODE) project is comprehensively mapping transcripts, histone modifications, chromosomal proteins, transcription factors, replication proteins and intermediates, and nucleosome properties across a developmental time course and in multiple cell lines. We have generated more than 700 data sets and discovered protein-coding, noncoding, RNA regulatory, replication, and chromatin elements, more than tripling the annotated portion of the Drosophila genome. Correlated activity patterns of these elements reveal a functional regulatory network, which predicts putative new functions for genes, reveals stage- and tissue-specific regulators, and enables gene-expression prediction. Our results provide a foundation for directed experimental and computational studies in Drosophila and related species and also a model for systematic data integration toward comprehensive genomic and functional annotation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3192495/" 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/PMC3192495/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉modENCODE Consortium -- Roy, Sushmita -- Ernst, Jason -- Kharchenko, Peter V -- Kheradpour, Pouya -- Negre, Nicolas -- Eaton, Matthew L -- Landolin, Jane M -- Bristow, Christopher A -- Ma, Lijia -- Lin, Michael F -- Washietl, Stefan -- Arshinoff, Bradley I -- Ay, Ferhat -- Meyer, Patrick E -- Robine, Nicolas -- Washington, Nicole L -- Di Stefano, Luisa -- Berezikov, Eugene -- Brown, Christopher D -- Candeias, Rogerio -- Carlson, Joseph W -- Carr, Adrian -- Jungreis, Irwin -- Marbach, Daniel -- Sealfon, Rachel -- Tolstorukov, Michael Y -- Will, Sebastian -- Alekseyenko, Artyom A -- Artieri, Carlo -- Booth, Benjamin W -- Brooks, Angela N -- Dai, Qi -- Davis, Carrie A -- Duff, Michael O -- Feng, Xin -- Gorchakov, Andrey A -- Gu, Tingting -- Henikoff, Jorja G -- Kapranov, Philipp -- Li, Renhua -- MacAlpine, Heather K -- Malone, John -- Minoda, Aki -- Nordman, Jared -- Okamura, Katsutomo -- Perry, Marc -- Powell, Sara K -- Riddle, Nicole C -- Sakai, Akiko -- Samsonova, Anastasia -- Sandler, Jeremy E -- Schwartz, Yuri B -- Sher, Noa -- Spokony, Rebecca -- Sturgill, David -- van Baren, Marijke -- Wan, Kenneth H -- Yang, Li -- Yu, Charles -- Feingold, Elise -- Good, Peter -- Guyer, Mark -- Lowdon, Rebecca -- Ahmad, Kami -- Andrews, Justen -- Berger, Bonnie -- Brenner, Steven E -- Brent, Michael R -- Cherbas, Lucy -- Elgin, Sarah C R -- Gingeras, Thomas R -- Grossman, Robert -- Hoskins, Roger A -- Kaufman, Thomas C -- Kent, William -- Kuroda, Mitzi I -- Orr-Weaver, Terry -- Perrimon, Norbert -- Pirrotta, Vincenzo -- Posakony, James W -- Ren, Bing -- Russell, Steven -- Cherbas, Peter -- Graveley, Brenton R -- Lewis, Suzanna -- Micklem, Gos -- Oliver, Brian -- Park, Peter J -- Celniker, Susan E -- Henikoff, Steven -- Karpen, Gary H -- Lai, Eric C -- MacAlpine, David M -- Stein, Lincoln D -- White, Kevin P -- Kellis, Manolis -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01HG004037/HG/NHGRI NIH HHS/ -- RC2HG005639/HG/NHGRI NIH HHS/ -- U01 HG004258/HG/NHGRI NIH HHS/ -- U01 HG004271/HG/NHGRI NIH HHS/ -- U01 HG004279/HG/NHGRI NIH HHS/ -- U01HG004258/HG/NHGRI NIH HHS/ -- U01HG004261/HG/NHGRI NIH HHS/ -- U01HG004264/HG/NHGRI NIH HHS/ -- U01HG004271/HG/NHGRI NIH HHS/ -- U01HG004274/HG/NHGRI NIH HHS/ -- U01HG004279/HG/NHGRI NIH HHS/ -- U41HG004269/HG/NHGRI NIH HHS/ -- ZIA DK015600-14/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1787-97. doi: 10.1126/science.1198374.

    Description: Three-prime untranslated regions (3'UTRs) of metazoan messenger RNAs (mRNAs) contain numerous regulatory elements, yet remain largely uncharacterized. Using polyA capture, 3' rapid amplification of complementary DNA (cDNA) ends, full-length cDNAs, and RNA-seq, we defined approximately 26,000 distinct 3'UTRs in Caenorhabditis elegans for approximately 85% of the 18,328 experimentally supported protein-coding genes and revised approximately 40% of gene models. Alternative 3'UTR isoforms are frequent, often differentially expressed during development. Average 3'UTR length decreases with animal age. Surprisingly, no polyadenylation signal (PAS) was detected for 13% of polyadenylation sites, predominantly among shorter alternative isoforms. Trans-spliced (versus non-trans-spliced) mRNAs possess longer 3'UTRs and frequently contain no PAS or variant PAS. We identified conserved 3'UTR motifs, isoform-specific predicted microRNA target sites, and polyadenylation of most histone genes. Our data reveal a rich complexity of 3'UTRs, both genome-wide and throughout development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3142571/" 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/PMC3142571/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mangone, Marco -- Manoharan, Arun Prasad -- Thierry-Mieg, Danielle -- Thierry-Mieg, Jean -- Han, Ting -- Mackowiak, Sebastian D -- Mis, Emily -- Zegar, Charles -- Gutwein, Michelle R -- Khivansara, Vishal -- Attie, Oliver -- Chen, Kevin -- Salehi-Ashtiani, Kourosh -- Vidal, Marc -- Harkins, Timothy T -- Bouffard, Pascal -- Suzuki, Yutaka -- Sugano, Sumio -- Kohara, Yuji -- Rajewsky, Nikolaus -- Piano, Fabio -- Gunsalus, Kristin C -- Kim, John K -- R00HG004515/HG/NHGRI NIH HHS/ -- R01 GM088565/GM/NIGMS NIH HHS/ -- R01 GM088565-03/GM/NIGMS NIH HHS/ -- R01GM088565/GM/NIGMS NIH HHS/ -- U01-HG004276/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):432-5. doi: 10.1126/science.1191244.

    Description: The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding studies. Many of its targets encode transcriptional regulators, including known floral repressors. The latter genes are down-regulated by AP1, suggesting that it initiates floral development by abrogating the inhibitory effects of these genes. Although AP1 acts predominantly as a transcriptional repressor during the earliest stages of flower development, at more advanced stages it also activates regulatory genes required for floral organ formation, indicating a dynamic mode of action. Our results further imply that AP1 orchestrates floral initiation by integrating growth, patterning, and hormonal pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaufmann, Kerstin -- Wellmer, Frank -- Muino, Jose M -- Ferrier, Thilia -- Wuest, Samuel E -- Kumar, Vijaya -- Serrano-Mislata, Antonio -- Madueno, Francisco -- Krajewski, Pawel -- Meyerowitz, Elliot M -- Angenent, Gerco C -- Riechmann, Jose Luis -- New York, N.Y. -- Science. 2010 Apr 2;328(5974):85-9. doi: 10.1126/science.1185244.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Business Unit Bioscience, Plant Research International, Wageningen 6700 AA, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20360106" target="_blank"〉PubMed〈/a〉

    Description: Coxsackie and adenovirus receptor (CAR) is the primary cellular receptor for group B coxsackieviruses and most adenovirus serotypes and plays a crucial role in adenoviral gene therapy. Recent discovery of the interaction between junctional adhesion molecule-like protein (JAML) and CAR uncovered important functional roles in immunity, inflammation, and tissue homeostasis. Crystal structures of JAML ectodomain (2.2 angstroms) and its complex with CAR (2.8 angstroms) reveal an unusual immunoglobulin-domain assembly for JAML and a charged interface that confers high specificity. Biochemical and mutagenesis studies illustrate how CAR-mediated clustering of JAML recruits phosphoinositide 3-kinase (P13K) to a JAML intracellular sequence motif as delineated for the alphabeta T cell costimulatory receptor CD28. Thus, CAR and JAML are cell signaling receptors of the immune system with implications for asthma, cancer, and chronic nonhealing wounds.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2951132/" 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/PMC2951132/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verdino, Petra -- Witherden, Deborah A -- Havran, Wendy L -- Wilson, Ian A -- AI064811/AI/NIAID NIH HHS/ -- AI42266/AI/NIAID NIH HHS/ -- AI52257/AI/NIAID NIH HHS/ -- CA58896/CA/NCI NIH HHS/ -- R01 AI036964/AI/NIAID NIH HHS/ -- R01 AI052257/AI/NIAID NIH HHS/ -- R01 AI052257-05/AI/NIAID NIH HHS/ -- R01 AI064811/AI/NIAID NIH HHS/ -- R01 AI064811-01A1/AI/NIAID NIH HHS/ -- R01 CA058896/CA/NCI NIH HHS/ -- R01 CA058896-16A1/CA/NCI NIH HHS/ -- R01 GM080301/GM/NIGMS NIH HHS/ -- R37 AI042266/AI/NIAID NIH HHS/ -- R37 AI042266-13/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 3;329(5996):1210-4. doi: 10.1126/science.1187996.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20813955" target="_blank"〉PubMed〈/a〉

    Description: Long intergenic noncoding RNAs (lincRNAs) regulate chromatin states and epigenetic inheritance. Here, we show that the lincRNA HOTAIR serves as a scaffold for at least two distinct histone modification complexes. A 5' domain of HOTAIR binds polycomb repressive complex 2 (PRC2), whereas a 3' domain of HOTAIR binds the LSD1/CoREST/REST complex. The ability to tether two distinct complexes enables RNA-mediated assembly of PRC2 and LSD1 and coordinates targeting of PRC2 and LSD1 to chromatin for coupled histone H3 lysine 27 methylation and lysine 4 demethylation. Our results suggest that lincRNAs may serve as scaffolds by providing binding surfaces to assemble select histone modification enzymes, thereby specifying the pattern of histone modifications on target genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2967777/" 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/PMC2967777/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Miao-Chih -- Manor, Ohad -- Wan, Yue -- Mosammaparast, Nima -- Wang, Jordon K -- Lan, Fei -- Shi, Yang -- Segal, Eran -- Chang, Howard Y -- R01 CA118750/CA/NCI NIH HHS/ -- R01 CA119176/CA/NCI NIH HHS/ -- R01 CA119176-05/CA/NCI NIH HHS/ -- R01-CA118487/CA/NCI NIH HHS/ -- R01-HG004361/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):689-93. doi: 10.1126/science.1192002.

    Description: Transcription factors (TFs) direct gene expression by binding to DNA regulatory regions. To explore the evolution of gene regulation, we used chromatin immunoprecipitation with high-throughput sequencing (ChIP-seq) to determine experimentally the genome-wide occupancy of two TFs, CCAAT/enhancer-binding protein alpha and hepatocyte nuclear factor 4 alpha, in the livers of five vertebrates. Although each TF displays highly conserved DNA binding preferences, most binding is species-specific, and aligned binding events present in all five species are rare. Regions near genes with expression levels that are dependent on a TF are often bound by the TF in multiple species yet show no enhanced DNA sequence constraint. Binding divergence between species can be largely explained by sequence changes to the bound motifs. Among the binding events lost in one lineage, only half are recovered by another binding event within 10 kilobases. Our results reveal large interspecies differences in transcriptional regulation and provide insight into regulatory evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" 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/PMC3008766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmidt, Dominic -- Wilson, Michael D -- Ballester, Benoit -- Schwalie, Petra C -- Brown, Gordon D -- Marshall, Aileen -- Kutter, Claudia -- Watt, Stephen -- Martinez-Jimenez, Celia P -- Mackay, Sarah -- Talianidis, Iannis -- Flicek, Paul -- Odom, Duncan T -- 062023/Wellcome Trust/United Kingdom -- 079643/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- WT062023/Wellcome Trust/United Kingdom -- WT079643/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2010 May 21;328(5981):1036-40. doi: 10.1126/science.1186176.

    Description: Host defense peptides such as defensins are components of innate immunity and have retained antibiotic activity throughout evolution. Their activity is thought to be due to amphipathic structures, which enable binding and disruption of microbial cytoplasmic membranes. Contrary to this, we show that plectasin, a fungal defensin, acts by directly binding the bacterial cell-wall precursor Lipid II. A wide range of genetic and biochemical approaches identify cell-wall biosynthesis as the pathway targeted by plectasin. In vitro assays for cell-wall synthesis identified Lipid II as the specific cellular target. Consistently, binding studies confirmed the formation of an equimolar stoichiometric complex between Lipid II and plectasin. Furthermore, key residues in plectasin involved in complex formation were identified using nuclear magnetic resonance spectroscopy and computational modeling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schneider, Tanja -- Kruse, Thomas -- Wimmer, Reinhard -- Wiedemann, Imke -- Sass, Vera -- Pag, Ulrike -- Jansen, Andrea -- Nielsen, Allan K -- Mygind, Per H -- Raventos, Dorotea S -- Neve, Soren -- Ravn, Birthe -- Bonvin, Alexandre M J J -- De Maria, Leonardo -- Andersen, Anders S -- Gammelgaard, Lora K -- Sahl, Hans-Georg -- Kristensen, Hans-Henrik -- New York, N.Y. -- Science. 2010 May 28;328(5982):1168-72. doi: 10.1126/science.1185723.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pharmaceutical Microbiology Section, Institute for Medical Microbiology, Immunology, and Parasitology, University of Bonn, D-53115 Bonn, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20508130" target="_blank"〉PubMed〈/a〉

    Description: Cbln1, secreted from cerebellar granule cells, and the orphan glutamate receptor delta2 (GluD2), expressed by Purkinje cells, are essential for synapse integrity between these neurons in adult mice. Nevertheless, no endogenous binding partners for these molecules have been identified. We found that Cbln1 binds directly to the N-terminal domain of GluD2. GluD2 expression by postsynaptic cells, combined with exogenously applied Cbln1, was necessary and sufficient to induce new synapses in vitro and in the adult cerebellum in vivo. Further, beads coated with recombinant Cbln1 directly induced presynaptic differentiation and indirectly caused clustering of postsynaptic molecules via GluD2. These results indicate that the Cbln1-GluD2 complex is a unique synapse organizer that acts bidirectionally on both pre- and postsynaptic components.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsuda, Keiko -- Miura, Eriko -- Miyazaki, Taisuke -- Kakegawa, Wataru -- Emi, Kyoichi -- Narumi, Sakae -- Fukazawa, Yugo -- Ito-Ishida, Aya -- Kondo, Tetsuro -- Shigemoto, Ryuichi -- Watanabe, Masahiko -- Yuzaki, Michisuke -- New York, N.Y. -- Science. 2010 Apr 16;328(5976):363-8. doi: 10.1126/science.1185152.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, School of Medicine, Keio University, Tokyo 160-8582, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20395510" target="_blank"〉PubMed〈/a〉

    Description: Synaptic vesicle fusion in brain synapses occurs in phases that are either tightly coupled to action potentials (synchronous), immediately following action potentials (asynchronous), or as stochastic events in the absence of action potentials (spontaneous). Synaptotagmin-1, -2, and -9 are vesicle-associated Ca2+ sensors for synchronous release. Here we found that double C2 domain (Doc2) proteins act as Ca2+ sensors to trigger spontaneous release. Although Doc2 proteins are cytosolic, they function analogously to synaptotagmin-1 but with a higher Ca2+ sensitivity. Doc2 proteins bound to N-ethylmaleimide-sensitive factor attachment receptor (SNARE) complexes in competition with synaptotagmin-1. Thus, different classes of multiple C2 domain-containing molecules trigger synchronous versus spontaneous fusion, which suggests a general mechanism for synaptic vesicle fusion triggered by the combined actions of SNAREs and multiple C2 domain-containing proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2846320/" 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/PMC2846320/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groffen, Alexander J -- Martens, Sascha -- Diez Arazola, Rocio -- Cornelisse, L Niels -- Lozovaya, Natalia -- de Jong, Arthur P H -- Goriounova, Natalia A -- Habets, Ron L P -- Takai, Yoshimi -- Borst, J Gerard -- Brose, Nils -- McMahon, Harvey T -- Verhage, Matthijs -- MC_U105178795/Medical Research Council/United Kingdom -- U.1051.02.007(78795)/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1614-8. doi: 10.1126/science.1183765.

    Description: Bacterial NusG is a highly conserved transcription factor that is required for most Rho activity in vivo. We show by nuclear magnetic resonance spectroscopy that Escherichia coli NusG carboxyl-terminal domain forms a complex alternatively with Rho or with transcription factor NusE, a protein identical to 30S ribosomal protein S10. Because NusG amino-terminal domain contacts RNA polymerase and the NusG carboxy-terminal domain interaction site of NusE is accessible in the ribosomal 30S subunit, NusG may act as a link between transcription and translation. Uncoupling of transcription and translation at the ends of bacterial operons enables transcription termination by Rho factor, and competition between ribosomal NusE and Rho for NusG helps to explain why Rho cannot terminate translated transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burmann, Bjorn M -- Schweimer, Kristian -- Luo, Xiao -- Wahl, Markus C -- Stitt, Barbara L -- Gottesman, Max E -- Rosch, Paul -- GM037219/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):501-4. doi: 10.1126/science.1184953.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lehrstuhl Biopolymere und Forschungszentrum fur Bio-Makromolekule, Universitat Bayreuth, Universitatsstrasse 30, 95447 Bayreuth, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413501" target="_blank"〉PubMed〈/a〉

    Description: The extent to which variation in chromatin structure and transcription factor binding may influence gene expression, and thus underlie or contribute to variation in phenotype, is unknown. To address this question, we cataloged both individual-to-individual variation and differences between homologous chromosomes within the same individual (allele-specific variation) in chromatin structure and transcription factor binding in lymphoblastoid cells derived from individuals of geographically diverse ancestry. Ten percent of active chromatin sites were individual-specific; a similar proportion were allele-specific. Both individual-specific and allele-specific sites were commonly transmitted from parent to child, which suggests that they are heritable features of the human genome. Our study shows that heritable chromatin status and transcription factor binding differ as a result of genetic variation and may underlie phenotypic variation in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929018/" 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/PMC2929018/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDaniell, Ryan -- Lee, Bum-Kyu -- Song, Lingyun -- Liu, Zheng -- Boyle, Alan P -- Erdos, Michael R -- Scott, Laura J -- Morken, Mario A -- Kucera, Katerina S -- Battenhouse, Anna -- Keefe, Damian -- Collins, Francis S -- Willard, Huntington F -- Lieb, Jason D -- Furey, Terrence S -- Crawford, Gregory E -- Iyer, Vishwanath R -- Birney, Ewan -- U54 HG004563/HG/NHGRI NIH HHS/ -- U54 HG004563-03/HG/NHGRI NIH HHS/ -- Z01 HG000024/HG/NHGRI NIH HHS/ -- Z01 HG000024-13/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):235-9. doi: 10.1126/science.1184655.

    Description: The interactions of protein kinases and phosphatases with their regulatory subunits and substrates underpin cellular regulation. We identified a kinase and phosphatase interaction (KPI) network of 1844 interactions in budding yeast by mass spectrometric analysis of protein complexes. The KPI network contained many dense local regions of interactions that suggested new functions. Notably, the cell cycle phosphatase Cdc14 associated with multiple kinases that revealed roles for Cdc14 in mitogen-activated protein kinase signaling, the DNA damage response, and metabolism, whereas interactions of the target of rapamycin complex 1 (TORC1) uncovered new effector kinases in nitrogen and carbon metabolism. An extensive backbone of kinase-kinase interactions cross-connects the proteome and may serve to coordinate diverse cellular responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3983991/" 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/PMC3983991/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breitkreutz, Ashton -- Choi, Hyungwon -- Sharom, Jeffrey R -- Boucher, Lorrie -- Neduva, Victor -- Larsen, Brett -- Lin, Zhen-Yuan -- Breitkreutz, Bobby-Joe -- Stark, Chris -- Liu, Guomin -- Ahn, Jessica -- Dewar-Darch, Danielle -- Reguly, Teresa -- Tang, Xiaojing -- Almeida, Ricardo -- Qin, Zhaohui Steve -- Pawson, Tony -- Gingras, Anne-Claude -- Nesvizhskii, Alexey I -- Tyers, Mike -- CA-126239/CA/NCI NIH HHS/ -- MOP-12246/Canadian Institutes of Health Research/Canada -- MOP-57793/Canadian Institutes of Health Research/Canada -- MOP-84314/Canadian Institutes of Health Research/Canada -- R01 CA126239/CA/NCI NIH HHS/ -- R01 GM094231/GM/NIGMS NIH HHS/ -- R01 OD010929/OD/NIH HHS/ -- R01 RR024031/RR/NCRR NIH HHS/ -- R01 RR024031-05/RR/NCRR NIH HHS/ -- R01RR024031/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2010 May 21;328(5981):1043-6. doi: 10.1126/science.1176495.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Systems Biology, Samuel Lunenfeld Research Institute, 600 University Avenue, Toronto, Ontario, M5G 1X5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20489023" target="_blank"〉PubMed〈/a〉

    Description: The marine bacterium Vibrio parahaemolyticus causes gastroenteritis in humans and encodes the type III effector protein VPA0450, which contributes to host cell death caused by autophagy, cell rounding, and cell lysis. We found that VPA0450 is an inositol polyphosphate 5-phosphatase that hydrolyzed the D5 phosphate from the plasma membrane phospholipid phosphatidylinositol 4,5-bisphosphate. VPA0450 disrupted cytoskeletal binding sites on the inner surface of membranes of human cells and caused plasma membrane blebbing, which compromised membrane integrity and probably contributed to cell death by facilitating lysis. Thus, bacterial pathogens can disrupt adaptor protein-binding sites required for proper membrane and cytoskeleton dynamics by altering the homeostasis of membrane-bound inositol-signaling molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Broberg, Christopher A -- Zhang, Lingling -- Gonzalez, Herman -- Laskowski-Arce, Michelle A -- Orth, Kim -- 5T32GM008203/GM/NIGMS NIH HHS/ -- R01-AI056404/AI/NIAID NIH HHS/ -- R01-AI087808/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 24;329(5999):1660-2. doi: 10.1126/science.1192850.

    Description: Dopamine modulates movement, cognition, and emotion through activation of dopamine G protein-coupled receptors in the brain. The crystal structure of the human dopamine D3 receptor (D3R) in complex with the small molecule D2R/D3R-specific antagonist eticlopride reveals important features of the ligand binding pocket and extracellular loops. On the intracellular side of the receptor, a locked conformation of the ionic lock and two distinctly different conformations of intracellular loop 2 are observed. Docking of R-22, a D3R-selective antagonist, reveals an extracellular extension of the eticlopride binding site that comprises a second binding pocket for the aryl amide of R-22, which differs between the highly homologous D2R and D3R. This difference provides direction to the design of D3R-selective agents for treating drug abuse and other neuropsychiatric indications.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058422/" 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/PMC3058422/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chien, Ellen Y T -- Liu, Wei -- Zhao, Qiang -- Katritch, Vsevolod -- Han, Gye Won -- Hanson, Michael A -- Shi, Lei -- Newman, Amy Hauck -- Javitch, Jonathan A -- Cherezov, Vadim -- Stevens, Raymond C -- DA022413/DA/NIDA NIH HHS/ -- DA023694/DA/NIDA NIH HHS/ -- GM075915/GM/NIGMS NIH HHS/ -- K05 DA022413/DA/NIDA NIH HHS/ -- K05 DA022413-05/DA/NIDA NIH HHS/ -- MH54137/MH/NIMH NIH HHS/ -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073197-07/GM/NIGMS NIH HHS/ -- R00 DA023694/DA/NIDA NIH HHS/ -- R00 DA023694-04/DA/NIDA NIH HHS/ -- R01 GM089857/GM/NIGMS NIH HHS/ -- R01 MH054137/MH/NIMH NIH HHS/ -- R01 MH054137-16/MH/NIMH NIH HHS/ -- R21 RR025336/RR/NCRR NIH HHS/ -- R21 RR025336-01A1/RR/NCRR NIH HHS/ -- U54 GM074961/GM/NIGMS NIH HHS/ -- U54 GM074961-050001/GM/NIGMS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- U54 GM094618-01/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Nov 19;330(6007):1091-5. doi: 10.1126/science.1197410.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21097933" target="_blank"〉PubMed〈/a〉

    Description: Crystallization of L-cystine is a critical step in the pathogenesis of cystine kidney stones. Treatments for this disease are somewhat effective but often lead to adverse side effects. Real-time in situ atomic force microscopy (AFM) reveals that L-cystine dimethylester (L-CDME) and L-cystine methylester (L-CME) dramatically reduce the growth velocity of the six symmetry-equivalent {100} steps because of specific binding at the crystal surface, which frustrates the attachment of L-cystine molecules. L-CDME and L-CME produce l-cystine crystals with different habits that reveal distinct binding modes at the crystal surfaces. The AFM observations are mirrored by reduced crystal yield and crystal size in the presence of L-CDME and L-CME, collectively suggesting a new pathway to the prevention of L-cystine stones by rational design of crystal growth inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rimer, Jeffrey D -- An, Zhihua -- Zhu, Zina -- Lee, Michael H -- Goldfarb, David S -- Wesson, Jeffrey A -- Ward, Michael D -- 1U54DK083908-01/DK/NIDDK NIH HHS/ -- R01 DK068551/DK/NIDDK NIH HHS/ -- R01-DK068551/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 15;330(6002):337-41. doi: 10.1126/science.1191968.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and the Molecular Design Institute, New York University (NYU), 100 Washington Square East, New York, NY 10003-6688, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20947757" target="_blank"〉PubMed〈/a〉

    Description: The control of RNA alternative splicing is critical for generating biological diversity. Despite emerging genome-wide technologies to study RNA complexity, reliable and comprehensive RNA-regulatory networks have not been defined. Here, we used Bayesian networks to probabilistically model diverse data sets and predict the target networks of specific regulators. We applied this strategy to identify approximately 700 alternative splicing events directly regulated by the neuron-specific factor Nova in the mouse brain, integrating RNA-binding data, splicing microarray data, Nova-binding motifs, and evolutionary signatures. The resulting integrative network revealed combinatorial regulation by Nova and the neuronal splicing factor Fox, interplay between phosphorylation and splicing, and potential links to neurologic disease. Thus, we have developed a general approach to understanding mammalian RNA regulation at the systems level.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3412410/" 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/PMC3412410/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Chaolin -- Frias, Maria A -- Mele, Aldo -- Ruggiu, Matteo -- Eom, Taesun -- Marney, Christina B -- Wang, Huidong -- Licatalosi, Donny D -- Fak, John J -- Darnell, Robert B -- K99 GM095713/GM/NIGMS NIH HHS/ -- NS34389/NS/NINDS NIH HHS/ -- UL1 RR024143/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):439-43. doi: 10.1126/science.1191150.
