    Description: The coagulation protease thrombin triggers fibrin formation, platelet activation, and other cellular responses at sites of tissue injury. We report a role for PAR1, a protease-activated G protein-coupled receptor for thrombin, in embryonic development. Approximately half of Par1-/- mouse embryos died at midgestation with bleeding from multiple sites. PAR1 is expressed in endothelial cells, and a PAR1 transgene driven by an endothelial-specific promoter prevented death of Par1-/- embryos. Our results suggest that the coagulation cascade and PAR1 modulate endothelial cell function in developing blood vessels and that thrombin's actions on endothelial cells-rather than on platelets, mesenchymal cells, or fibrinogen-contribute to vascular development and hemostasis in the mouse embryo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffin, C T -- Srinivasan, Y -- Zheng, Y W -- Huang, W -- Coughlin, S R -- HL44907/HL/NHLBI NIH HHS/ -- HL65590/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2001 Aug 31;293(5535):1666-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiovascular Research Institute, University of California at San Francisco (UCSF), San Francisco, California 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11533492" target="_blank"〉PubMed〈/a〉

    Description: The first chordates appear in the fossil record at the time of the Cambrian explosion, nearly 550 million years ago. The modern ascidian tadpole represents a plausible approximation to these ancestral chordates. To illuminate the origins of chordate and vertebrates, we generated a draft of the protein-coding portion of the genome of the most studied ascidian, Ciona intestinalis. The Ciona genome contains approximately 16,000 protein-coding genes, similar to the number in other invertebrates, but only half that found in vertebrates. Vertebrate gene families are typically found in simplified form in Ciona, suggesting that ascidians contain the basic ancestral complement of genes involved in cell signaling and development. The ascidian genome has also acquired a number of lineage-specific innovations, including a group of genes engaged in cellulose metabolism that are related to those in bacteria and fungi.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehal, Paramvir -- Satou, Yutaka -- Campbell, Robert K -- Chapman, Jarrod -- Degnan, Bernard -- De Tomaso, Anthony -- Davidson, Brad -- Di Gregorio, Anna -- Gelpke, Maarten -- Goodstein, David M -- Harafuji, Naoe -- Hastings, Kenneth E M -- Ho, Isaac -- Hotta, Kohji -- Huang, Wayne -- Kawashima, Takeshi -- Lemaire, Patrick -- Martinez, Diego -- Meinertzhagen, Ian A -- Necula, Simona -- Nonaka, Masaru -- Putnam, Nik -- Rash, Sam -- Saiga, Hidetoshi -- Satake, Masanobu -- Terry, Astrid -- Yamada, Lixy -- Wang, Hong-Gang -- Awazu, Satoko -- Azumi, Kaoru -- Boore, Jeffrey -- Branno, Margherita -- Chin-Bow, Stephen -- DeSantis, Rosaria -- Doyle, Sharon -- Francino, Pilar -- Keys, David N -- Haga, Shinobu -- Hayashi, Hiroko -- Hino, Kyosuke -- Imai, Kaoru S -- Inaba, Kazuo -- Kano, Shungo -- Kobayashi, Kenji -- Kobayashi, Mari -- Lee, Byung-In -- Makabe, Kazuhiro W -- Manohar, Chitra -- Matassi, Giorgio -- Medina, Monica -- Mochizuki, Yasuaki -- Mount, Steve -- Morishita, Tomomi -- Miura, Sachiko -- Nakayama, Akie -- Nishizaka, Satoko -- Nomoto, Hisayo -- Ohta, Fumiko -- Oishi, Kazuko -- Rigoutsos, Isidore -- Sano, Masako -- Sasaki, Akane -- Sasakura, Yasunori -- Shoguchi, Eiichi -- Shin-i, Tadasu -- Spagnuolo, Antoinetta -- Stainier, Didier -- Suzuki, Miho M -- Tassy, Olivier -- Takatori, Naohito -- Tokuoka, Miki -- Yagi, Kasumi -- Yoshizaki, Fumiko -- Wada, Shuichi -- Zhang, Cindy -- Hyatt, P Douglas -- Larimer, Frank -- Detter, Chris -- Doggett, Norman -- Glavina, Tijana -- Hawkins, Trevor -- Richardson, Paul -- Lucas, Susan -- Kohara, Yuji -- Levine, Michael -- Satoh, Nori -- Rokhsar, Daniel S -- HD-37105/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2002 Dec 13;298(5601):2157-67.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12481130" target="_blank"〉PubMed〈/a〉

    Description: To test the hypotheses of modern human origin in East Asia, we sampled 12,127 male individuals from 163 populations and typed for three Y chromosome biallelic markers (YAP, M89, and M130). All the individuals carried a mutation at one of the three sites. These three mutations (YAP+, M89T, and M130T) coalesce to another mutation (M168T), which originated in Africa about 35,000 to 89,000 years ago. Therefore, the data do not support even a minimal in situ hominid contribution in the origin of anatomically modern humans in East Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ke, Y -- Su, B -- Song, X -- Lu, D -- Chen, L -- Li, H -- Qi, C -- Marzuki, S -- Deka, R -- Underhill, P -- Xiao, C -- Shriver, M -- Lell, J -- Wallace, D -- Wells, R S -- Seielstad, M -- Oefner, P -- Zhu, D -- Jin, J -- Huang, W -- Chakraborty, R -- Chen, Z -- Jin, L -- New York, N.Y. -- Science. 2001 May 11;292(5519):1151-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Genetic Engineering, Institute of Genetics, School of Life Sciences, Fudan University, 220 Handan Road, Shanghai, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11349147" target="_blank"〉PubMed〈/a〉

    Description: FocA is a representative member of the formate-nitrite transporter family, which transports short-chain acids in bacteria, archaea, fungi, algae and parasites. The structure and transport mechanism of the formate-nitrite transporter family remain unknown. Here we report the crystal structure of Escherichia coli FocA at 2.25 A resolution. FocA forms a symmetric pentamer, with each protomer consisting of six transmembrane segments. Despite a lack of sequence homology, the overall structure of the FocA protomer closely resembles that of aquaporin and strongly argues that FocA is a channel, rather than a transporter. Structural analysis identifies potentially important channel residues, defines the channel path and reveals two constriction sites. Unlike aquaporin, FocA is impermeable to water but allows the passage of formate. A structural and biochemical investigation provides mechanistic insights into the channel activity of FocA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Yi -- Huang, Yongjian -- Wang, Jiawei -- Cheng, Chao -- Huang, Weijiao -- Lu, Peilong -- Xu, Ya-Nan -- Wang, Pengye -- Yan, Nieng -- Shi, Yigong -- England -- Nature. 2009 Nov 26;462(7272):467-72. doi: 10.1038/nature08610.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ministry of Education Protein Science Laboratory, Center for Structural Biology, School of Life Sciences and School of Medicine, Tsinghua University, Beijing 100084, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19940917" target="_blank"〉PubMed〈/a〉

    Description: T-helper type 17 (TH17) cells that produce the cytokines interleukin-17A (IL-17A) and IL-17F are implicated in the pathogenesis of several autoimmune diseases. The differentiation of TH17 cells is regulated by transcription factors such as RORgammat, but post-translational mechanisms preventing the rampant production of pro-inflammatory IL-17A have received less attention. Here we show that the deubiquitylating enzyme DUBA is a negative regulator of IL-17A production in T cells. Mice with DUBA-deficient T cells developed exacerbated inflammation in the small intestine after challenge with anti-CD3 antibodies. DUBA interacted with the ubiquitin ligase UBR5, which suppressed DUBA abundance in naive T cells. DUBA accumulated in activated T cells and stabilized UBR5, which then ubiquitylated RORgammat in response to TGF-beta signalling. Our data identify DUBA as a cell-intrinsic suppressor of IL-17 production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rutz, Sascha -- Kayagaki, Nobuhiko -- Phung, Qui T -- Eidenschenk, Celine -- Noubade, Rajkumar -- Wang, Xiaoting -- Lesch, Justin -- Lu, Rongze -- Newton, Kim -- Huang, Oscar W -- Cochran, Andrea G -- Vasser, Mark -- Fauber, Benjamin P -- DeVoss, Jason -- Webster, Joshua -- Diehl, Lauri -- Modrusan, Zora -- Kirkpatrick, Donald S -- Lill, Jennie R -- Ouyang, Wenjun -- Dixit, Vishva M -- England -- Nature. 2015 Feb 19;518(7539):417-21. doi: 10.1038/nature13979.

    Description: Draft genome sequences have been determined for the soybean pathogen Phytophthora sojae and the sudden oak death pathogen Phytophthora ramorum. Oomycetes such as these Phytophthora species share the kingdom Stramenopila with photosynthetic algae such as diatoms, and the presence of many Phytophthora genes of probable phototroph origin supports a photosynthetic ancestry for the stramenopiles. Comparison of the two species' genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oomycete avirulence genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tyler, Brett M -- Tripathy, Sucheta -- Zhang, Xuemin -- Dehal, Paramvir -- Jiang, Rays H Y -- Aerts, Andrea -- Arredondo, Felipe D -- Baxter, Laura -- Bensasson, Douda -- Beynon, Jim L -- Chapman, Jarrod -- Damasceno, Cynthia M B -- Dorrance, Anne E -- Dou, Daolong -- Dickerman, Allan W -- Dubchak, Inna L -- Garbelotto, Matteo -- Gijzen, Mark -- Gordon, Stuart G -- Govers, Francine -- Grunwald, Niklaus J -- Huang, Wayne -- Ivors, Kelly L -- Jones, Richard W -- Kamoun, Sophien -- Krampis, Konstantinos -- Lamour, Kurt H -- Lee, Mi-Kyung -- McDonald, W Hayes -- Medina, Monica -- Meijer, Harold J G -- Nordberg, Eric K -- Maclean, Donald J -- Ospina-Giraldo, Manuel D -- Morris, Paul F -- Phuntumart, Vipaporn -- Putnam, Nicholas H -- Rash, Sam -- Rose, Jocelyn K C -- Sakihama, Yasuko -- Salamov, Asaf A -- Savidor, Alon -- Scheuring, Chantel F -- Smith, Brian M -- Sobral, Bruno W S -- Terry, Astrid -- Torto-Alalibo, Trudy A -- Win, Joe -- Xu, Zhanyou -- Zhang, Hongbin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Boore, Jeffrey L -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1261-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Virginia Bioinformatics Institute, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA. bmtyler@vt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946064" target="_blank"〉PubMed〈/a〉

    Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" 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/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉

    Description: Atrial fibrillation (AF) is a common cardiac arrhythmia whose molecular etiology is poorly understood. We studied a family with hereditary persistent AF and identified the causative mutation (S140G) in the KCNQ1 (KvLQT1) gene on chromosome 11p15.5. The KCNQ1 gene encodes the pore-forming alpha subunit of the cardiac I(Ks) channel (KCNQ1/KCNE1), the KCNQ1/KCNE2 and the KCNQ1/KCNE3 potassium channels. Functional analysis of the S140G mutant revealed a gain-of-function effect on the KCNQ1/KCNE1 and the KCNQ1/KCNE2 currents, which contrasts with the dominant negative or loss-of-function effects of the KCNQ1 mutations previously identified in patients with long QT syndrome. Thus, the S140G mutation is likely to initiate and maintain AF by reducing action potential duration and effective refractory period in atrial myocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Yi-Han -- Xu, Shi-Jie -- Bendahhou, Said -- Wang, Xiao-Liang -- Wang, Ying -- Xu, Wen-Yuan -- Jin, Hong-Wei -- Sun, Hao -- Su, Xiao-Yan -- Zhuang, Qi-Nan -- Yang, Yi-Qing -- Li, Yue-Bin -- Liu, Yi -- Xu, Hong-Ju -- Li, Xiao-Fei -- Ma, Ning -- Mou, Chun-Ping -- Chen, Zhu -- Barhanin, Jacques -- Huang, Wei -- New York, N.Y. -- Science. 2003 Jan 10;299(5604):251-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cardiology, Tongji Hospital, and Institute of Medical Genetics, Tongji University, 399 Xin Cun Road, Shanghai 200065, People's Republic of China. drchen@public7.sta.net.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12522251" target="_blank"〉PubMed〈/a〉
