    Human chromosome 7: DNA sequence and biology (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-12
    Description: DNA sequence and annotation of the entire human chromosome 7, encompassing nearly 158 million nucleotides of DNA and 1917 gene structures, are presented. To generate a higher order description, additional structural features such as imprinted genes, fragile sites, and segmental duplications were integrated at the level of the DNA sequence with medical genetic data, including 440 chromosome rearrangement breakpoints associated with disease. This approach enabled the discovery of candidate genes for developmental diseases including autism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882961/" 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/PMC2882961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherer, Stephen W -- Cheung, Joseph -- MacDonald, Jeffrey R -- Osborne, Lucy R -- Nakabayashi, Kazuhiko -- Herbrick, Jo-Anne -- Carson, Andrew R -- Parker-Katiraee, Layla -- Skaug, Jennifer -- Khaja, Razi -- Zhang, Junjun -- Hudek, Alexander K -- Li, Martin -- Haddad, May -- Duggan, Gavin E -- Fernandez, Bridget A -- Kanematsu, Emiko -- Gentles, Simone -- Christopoulos, Constantine C -- Choufani, Sanaa -- Kwasnicka, Dorota -- Zheng, Xiangqun H -- Lai, Zhongwu -- Nusskern, Deborah -- Zhang, Qing -- Gu, Zhiping -- Lu, Fu -- Zeesman, Susan -- Nowaczyk, Malgorzata J -- Teshima, Ikuko -- Chitayat, David -- Shuman, Cheryl -- Weksberg, Rosanna -- Zackai, Elaine H -- Grebe, Theresa A -- Cox, Sarah R -- Kirkpatrick, Susan J -- Rahman, Nazneen -- Friedman, Jan M -- Heng, Henry H Q -- Pelicci, Pier Giuseppe -- Lo-Coco, Francesco -- Belloni, Elena -- Shaffer, Lisa G -- Pober, Barbara -- Morton, Cynthia C -- Gusella, James F -- Bruns, Gail A P -- Korf, Bruce R -- Quade, Bradley J -- Ligon, Azra H -- Ferguson, Heather -- Higgins, Anne W -- Leach, Natalia T -- Herrick, Steven R -- Lemyre, Emmanuelle -- Farra, Chantal G -- Kim, Hyung-Goo -- Summers, Anne M -- Gripp, Karen W -- Roberts, Wendy -- Szatmari, Peter -- Winsor, Elizabeth J T -- Grzeschik, Karl-Heinz -- Teebi, Ahmed -- Minassian, Berge A -- Kere, Juha -- Armengol, Lluis -- Pujana, Miguel Angel -- Estivill, Xavier -- Wilson, Michael D -- Koop, Ben F -- Tosi, Sabrina -- Moore, Gudrun E -- Boright, Andrew P -- Zlotorynski, Eitan -- Kerem, Batsheva -- Kroisel, Peter M -- Petek, Erwin -- Oscier, David G -- Mould, Sarah J -- Dohner, Hartmut -- Dohner, Konstanze -- Rommens, Johanna M -- Vincent, John B -- Venter, J Craig -- Li, Peter W -- Mural, Richard J -- Adams, Mark D -- Tsui, Lap-Chee -- 38103/Canadian Institutes of Health Research/Canada -- P01 GM061354/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 2;300(5620):767-72.

    Characterization of a novel coronavirus associated with severe acute respiratory syndrome (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-06
    Description: In March 2003, a novel coronavirus (SARS-CoV) was discovered in association with cases of severe acute respiratory syndrome (SARS). The sequence of the complete genome of SARS-CoV was determined, and the initial characterization of the viral genome is presented in this report. The genome of SARS-CoV is 29,727 nucleotides in length and has 11 open reading frames, and its genome organization is similar to that of other coronaviruses. Phylogenetic analyses and sequence comparisons showed that SARS-CoV is not closely related to any of the previously characterized coronaviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rota, Paul A -- Oberste, M Steven -- Monroe, Stephan S -- Nix, W Allan -- Campagnoli, Ray -- Icenogle, Joseph P -- Penaranda, Silvia -- Bankamp, Bettina -- Maher, Kaija -- Chen, Min-Hsin -- Tong, Suxiong -- Tamin, Azaibi -- Lowe, Luis -- Frace, Michael -- DeRisi, Joseph L -- Chen, Qi -- Wang, David -- Erdman, Dean D -- Peret, Teresa C T -- Burns, Cara -- Ksiazek, Thomas G -- Rollin, Pierre E -- Sanchez, Anthony -- Liffick, Stephanie -- Holloway, Brian -- Limor, Josef -- McCaustland, Karen -- Olsen-Rasmussen, Melissa -- Fouchier, Ron -- Gunther, Stephan -- Osterhaus, Albert D M E -- Drosten, Christian -- Pallansch, Mark A -- Anderson, Larry J -- Bellini, William J -- New York, N.Y. -- Science. 2003 May 30;300(5624):1394-9.

    Genome-wide survey of human alternative pre-mRNA splicing with exon junction microarrays (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-20
    Description: Alternative pre-messenger RNA (pre-mRNA) splicing plays important roles in development, physiology, and disease, and more than half of human genes are alternatively spliced. To understand the biological roles and regulation of alternative splicing across different tissues and stages of development, systematic methods are needed. Here, we demonstrate the use of microarrays to monitor splicing at every exon-exon junction in more than 10,000 multi-exon human genes in 52 tissues and cell lines. These genome-wide data provide experimental evidence and tissue distributions for thousands of known and novel alternative splicing events. Adding to previous studies, the results indicate that at least 74% of human multi-exon genes are alternatively spliced.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, Jason M -- Castle, John -- Garrett-Engele, Philip -- Kan, Zhengyan -- Loerch, Patrick M -- Armour, Christopher D -- Santos, Ralph -- Schadt, Eric E -- Stoughton, Roland -- Shoemaker, Daniel D -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2141-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rosetta Inpharmatics LLC, Merck & Co., Inc., 12040 115th Avenue N.E., Kirkland, WA 98034, USA. jason_johnson@merck.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14684825" target="_blank"〉PubMed〈/a〉

    Antibody domain exchange is an immunological solution to carbohydrate cluster recognition (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-06-28
    Description: Human antibody 2G12 neutralizes a broad range of human immunodeficiency virus type 1 (HIV-1) isolates by binding an unusually dense cluster of carbohydrate moieties on the "silent" face of the gp120 envelope glycoprotein. Crystal structures of Fab 2G12 and its complexes with the disaccharide Manalpha1-2Man and with the oligosaccharide Man9GlcNAc2 revealed that two Fabs assemble into an interlocked VH domain-swapped dimer. Further biochemical, biophysical, and mutagenesis data strongly support a Fab-dimerized antibody as the prevalent form that recognizes gp120. The extraordinary configuration of this antibody provides an extended surface, with newly described binding sites, for multivalent interaction with a conserved cluster of oligomannose type sugars on the surface of gp120. The unique interdigitation of Fab domains within an antibody uncovers a previously unappreciated mechanism for high-affinity recognition of carbohydrate or other repeating epitopes on cell or microbial surfaces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calarese, Daniel A -- Scanlan, Christopher N -- Zwick, Michael B -- Deechongkit, Songpon -- Mimura, Yusuke -- Kunert, Renate -- Zhu, Ping -- Wormald, Mark R -- Stanfield, Robyn L -- Roux, Kenneth H -- Kelly, Jeffery W -- Rudd, Pauline M -- Dwek, Raymond A -- Katinger, Hermann -- Burton, Dennis R -- Wilson, Ian A -- AI33292/AI/NIAID NIH HHS/ -- GM46192/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2065-71.〈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/12829775" target="_blank"〉PubMed〈/a〉

    Cell corpse engulfment mediated by C. elegans phosphatidylserine receptor through CED-5 and CED-12 (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-04
    Description: During apoptosis, phosphatidylserine, which is normally restricted to the inner leaflet of the plasma membrane, is exposed on the surface of apoptotic cells and has been suggested to act as an "eat-me" signal to trigger phagocytosis. It is unclear how phagocytes recognize phosphatidylserine. Recently, a putative phosphatidylserine receptor (PSR) was identified and proposed to mediate recognition of phosphatidylserine and phagocytosis. We report that psr-1, the Caenorhabditis elegans homolog of PSR, is important for cell corpse engulfment. In vitro PSR-1 binds preferentially phosphatidylserine or cells with exposed phosphatidylserine. In C. elegans, PSR-1 acts in the same cell corpse engulfment pathway mediated by intracellular signaling molecules CED-2 (homologous to the human CrkII protein), CED-5 (DOCK180), CED-10 (Rac GTPase), and CED-12 (ELMO), possibly through direct interaction with CED-5 and CED-12. Our findings suggest that PSR-1 is likely an upstream receptor for the signaling pathway containing CED-2, CED-5, CED-10, and CED-12 proteins and plays an important role in recognizing phosphatidylserine during phagocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Xiaochen -- Wu, Yi-Chun -- Fadok, Valerie A -- Lee, Ming-Chia -- Gengyo-Ando, Keiko -- Cheng, Li-Chun -- Ledwich, Duncan -- Hsu, Pei-Ken -- Chen, Jia-Yun -- Chou, Bin-Kuan -- Henson, Peter -- Mitani, Shohei -- Xue, Ding -- New York, N.Y. -- Science. 2003 Nov 28;302(5650):1563-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Cellular, and Developmental Biology, University of Colorado, Boulder, CO 80309, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14645848" target="_blank"〉PubMed〈/a〉

    A modular PIP2 binding site as a determinant of capsaicin receptor sensitivity (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-24
    Description: The capsaicin receptor (TRPV1), a heat-activated ion channel of the pain pathway, is sensitized by phosphatidylinositol-4,5-bisphosphate (PIP2) hydrolysis after phospholipase C activation. We identify a site within the C-terminal domain of TRPV1 that is required for PIP2-mediated inhibition of channel gating. Mutations that weaken PIP2-TRPV1 interaction reduce thresholds for chemical or thermal stimuli, whereas TRPV1 channels in which this region is replaced with a lipid-binding domain from PIP2-activated potassium channels remain inhibited by PIP2. The PIP2-interaction domain therefore serves as a critical determinant of thermal threshold and dynamic sensitivity range, tuning TRPV1, and thus the sensory neuron, to appropriately detect heat under normal or pathophysiological conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prescott, Elizabeth D -- Julius, David -- New York, N.Y. -- Science. 2003 May 23;300(5623):1284-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, CA 94143-2140, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12764195" target="_blank"〉PubMed〈/a〉

    Crystal structure of the potassium channel KirBac1.1 in the closed state (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-10
    Description: The KirBac1.1 channel belongs to the inward-rectifier family of potassium channels. Here we report the structure of the entire prokaryotic Kir channel assembly, in the closed state, refined to a resolution of 3.65 angstroms. We identify the main activation gate and structural elements involved in gating. On the basis of structural evidence presented here, we suggest that gating involves coupling between the intracellular and membrane domains. This further suggests that initiation of gating by membrane or intracellular signals represents different entry points to a common mechanistic pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuo, Anling -- Gulbis, Jacqueline M -- Antcliff, Jennifer F -- Rahman, Tahmina -- Lowe, Edward D -- Zimmer, Jochen -- Cuthbertson, Jonathan -- Ashcroft, Frances M -- Ezaki, Takayuki -- Doyle, Declan A -- New York, N.Y. -- Science. 2003 Jun 20;300(5627):1922-6.

    Keeping G proteins at bay: a complex between G protein-coupled receptor kinase 2 and Gbetagamma (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-24
    Description: The phosphorylation of heptahelical receptors by heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptor kinases (GRKs) is a universal regulatory mechanism that leads to desensitization of G protein signaling and to the activation of alternative signaling pathways. We determined the crystallographic structure of bovine GRK2 in complex with G protein beta1gamma2 subunits. Our results show how the three domains of GRK2-the RGS (regulator of G protein signaling) homology, protein kinase, and pleckstrin homology domains-integrate their respective activities and recruit the enzyme to the cell membrane in an orientation that not only facilitates receptor phosphorylation, but also allows for the simultaneous inhibition of signaling by Galpha and Gbetagamma subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lodowski, David T -- Pitcher, Julie A -- Capel, W Darrell -- Lefkowitz, Robert J -- Tesmer, John J G -- HL16037/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2003 May 23;300(5623):1256-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Cellular and Molecular Biology, Department of Chemistry and Biochemistry, University of Texas at Austin, Austin, TX 78712, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12764189" target="_blank"〉PubMed〈/a〉

    Role of anthocyanidin reductase, encoded by BANYULS in plant flavonoid biosynthesis (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-18
    Description: Condensed tannins (CTs) are flavonoid oligomers, many of which have beneficial effects on animal and human health. The flavanol (-)-epicatechin is a component of many CTs and contributes to flavor and astringency in tea and wine. We show that the BANYULS (BAN) genes from Arabidopsis thaliana and Medicago truncatula encode anthocyanidin reductase, which converts anthocyanidins to their corresponding 2,3-cis-flavan-3-ols. Ectopic expression of BAN in tobacco flower petals and Arabidopsis leaves results in loss of anthocyanins and accumulation of CTs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, De-Yu -- Sharma, Shashi B -- Paiva, Nancy L -- Ferreira, Daneel -- Dixon, Richard A -- New York, N.Y. -- Science. 2003 Jan 17;299(5605):396-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Biology Division, Samuel Roberts Noble Foundation, 2510 Sam Noble Parkway, Ardmore, OK 73401, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12532018" target="_blank"〉PubMed〈/a〉

    Recent expansion of Toxoplasma through enhanced oral transmission (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-18
    Description: The global predominance of three clonal Toxoplasma gondii lineages suggests that they are endowed with an exceptional trait responsible for their current parasitism of nearly all warm-blooded vertebrates. Genetic polymorphism analyses indicate that these clonal lineages emerged within the last 10,000 years after a single genetic cross. Comparison with ancient strains (approximately 1 million years) suggests that the success of the clonal lineages resulted from the concurrent acquisition of direct oral infectivity. This key adaptation circumvented sexual recombination, simultaneously promoting transmission through successive hosts, hence leading to clonal expansion. Thus, changes in complex life cycles can occur rapidly and can profoundly influence pathogenicity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, C -- Evans, D -- Cole, R H -- Kissinger, J C -- Ajioka, J W -- Sibley, L D -- New York, N.Y. -- Science. 2003 Jan 17;299(5605):414-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology, Washington University, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12532022" target="_blank"〉PubMed〈/a〉
