    The draft genome of Ciona intestinalis: insights into chordate and vertebrate origins (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-12-14
    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〉

    De novo protein design: fully automated sequence selection (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-10-06
    Description: The first fully automated design and experimental validation of a novel sequence for an entire protein is described. A computational design algorithm based on physical chemical potential functions and stereochemical constraints was used to screen a combinatorial library of 1.9 x 10(27) possible amino acid sequences for compatibility with the design target, a betabetaalpha protein motif based on the polypeptide backbone structure of a zinc finger domain. A BLAST search shows that the designed sequence, full sequence design 1 (FSD-1), has very low identity to any known protein sequence. The solution structure of FSD-1 was solved by nuclear magnetic resonance spectroscopy and indicates that FSD-1 forms a compact well-ordered structure, which is in excellent agreement with the design target structure. This result demonstrates that computational methods can perform the immense combinatorial search required for protein design, and it suggests that an unbiased and quantitative algorithm can be used in various structural contexts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dahiyat, B I -- Mayo, S L -- GM08346/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):82-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311930" target="_blank"〉PubMed〈/a〉

    Identification of a thyroid hormone receptor that is pituitary-specific (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-07
    Description: Three cellular homologs of the v-erbA oncogene were previously identified in the rat; two of them encode high affinity receptors for the thyroid hormone triiodothyronine (T3). A rat complementary DNA clone encoding a T3 receptor form of the ErbA protein, called r-ErbA beta-2, was isolated. The r-ErbA beta-2 protein differs at its amino terminus from the previously described rat protein encoded by c-erbA beta and referred to as r-ErbA beta-1. Unlike the other members of the c-erbA proto-oncogene family, which have a wide tissue distribution, r-erbA beta-2 appears to be expressed only in the anterior pituitary gland. In addition, thyroid hormone downregulates r-erbA beta-2 messenger RNA but not r-erbA beta-1 messenger RNA in a pituitary tumor-derived cell line. The presence of a pituitary-specific form of the thyroid hormone receptor that may be selectively regulated by thyroid hormone could be important for the differential regulation of gene expression by T3 in the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodin, R A -- Lazar, M A -- Wintman, B I -- Darling, D S -- Koenig, R J -- Larsen, P R -- Moore, D D -- Chin, W W -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):76-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539642" target="_blank"〉PubMed〈/a〉

    Cloning and expression of a rat brain GABA transporter (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-14
    Description: A complementary DNA clone (designated GAT-1) encoding a transporter for the neurotransmitter gamma-aminobutyric acid (GABA) has been isolated from rat brain, and its functional properties have been examined in Xenopus oocytes. Oocytes injected with GAT-1 synthetic messenger RNA accumulated [3H]GABA to levels above control values. The transporter encoded by GAT-1 has a high affinity for GABA, is sodium-and chloride-dependent, and is pharmacologically similar to neuronal GABA transporters. The GAT-1 protein shares antigenic determinants with a native rat brain GABA transporter. The nucleotide sequence of GAT-1 predicts a protein of 599 amino acids with a molecular weight of 67 kilodaltons. Hydropathy analysis of the deduced protein suggests multiple transmembrane regions, a feature shared by several cloned transporters; however, database searches indicate that GAT-1 is not homologous to any previously identified proteins. Therefore, GAT-1 appears to be a member of a previously uncharacterized family of transport molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guastella, J -- Nelson, N -- Nelson, H -- Czyzyk, L -- Keynan, S -- Miedel, M C -- Davidson, N -- Lester, H A -- Kanner, B I -- GM 10991/GM/NIGMS NIH HHS/ -- GM 29836/GM/NIGMS NIH HHS/ -- NS 16708/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 Sep 14;249(4974):1303-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1975955" target="_blank"〉PubMed〈/a〉

    Metagenome mining reveals polytheonamides as posttranslationally modified ribosomal peptides (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-18
    Description: It is held as a paradigm that ribosomally synthesized peptides and proteins contain only l-amino acids. We demonstrate a ribosomal origin of the marine sponge-derived polytheonamides, exceptionally potent, giant natural-product toxins. Isolation of the biosynthetic genes from the sponge metagenome revealed a bacterial gene architecture. Only six candidate enzymes were identified for 48 posttranslational modifications, including 18 epimerizations and 17 methylations of nonactivated carbon centers. Three enzymes were functionally validated, which showed that a radical S-adenosylmethionine enzyme is responsible for the unidirectional epimerization of multiple and different amino acids. Collectively, these complex alterations create toxins that function as unimolecular minimalistic ion channels with near-femtomolar activity. This study broadens the biosynthetic scope of ribosomal systems and creates new opportunities for peptide and protein bioengineering.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freeman, Michael F -- Gurgui, Cristian -- Helf, Maximilian J -- Morinaka, Brandon I -- Uria, Agustinus R -- Oldham, Neil J -- Sahl, Hans-Georg -- Matsunaga, Shigeki -- Piel, Jorn -- New York, N.Y. -- Science. 2012 Oct 19;338(6105):387-90. doi: 10.1126/science.1226121.

    Evolutionarily dynamic alternative splicing of GPR56 regulates regional cerebral cortical patterning (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-02-18
    Description: The human neocortex has numerous specialized functional areas whose formation is poorly understood. Here, we describe a 15-base pair deletion mutation in a regulatory element of GPR56 that selectively disrupts human cortex surrounding the Sylvian fissure bilaterally including "Broca's area," the primary language area, by disrupting regional GPR56 expression and blocking RFX transcription factor binding. GPR56 encodes a heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptor required for normal cortical development and is expressed in cortical progenitor cells. GPR56 expression levels regulate progenitor proliferation. GPR56 splice forms are highly variable between mice and humans, and the regulatory element of gyrencephalic mammals directs restricted lateral cortical expression. Our data reveal a mechanism by which control of GPR56 expression pattern by multiple alternative promoters can influence stem cell proliferation, gyral patterning, and, potentially, neocortex evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4480613/" 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/PMC4480613/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bae, Byoung-Il -- Tietjen, Ian -- Atabay, Kutay D -- Evrony, Gilad D -- Johnson, Matthew B -- Asare, Ebenezer -- Wang, Peter P -- Murayama, Ayako Y -- Im, Kiho -- Lisgo, Steven N -- Overman, Lynne -- Sestan, Nenad -- Chang, Bernard S -- Barkovich, A James -- Grant, P Ellen -- Topcu, Meral -- Politsky, Jeffrey -- Okano, Hideyuki -- Piao, Xianhua -- Walsh, Christopher A -- 2R01NS035129/NS/NINDS NIH HHS/ -- G0700089/Medical Research Council/United Kingdom -- GR082557/Wellcome Trust/United Kingdom -- HHSN275200900011C/PHS HHS/ -- N01-HD-9-0011/HD/NICHD NIH HHS/ -- R01 NS035129/NS/NINDS NIH HHS/ -- U01 MH081896/MH/NIMH NIH HHS/ -- U01MH081896/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):764-8. doi: 10.1126/science.1244392.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics and Genomics, Manton Center for Orphan Disease, and Howard Hughes Medical Institute, Boston Children's Hospital, Broad Institute of MIT and Harvard, and Departments of Pediatrics and Neurology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24531968" target="_blank"〉PubMed〈/a〉

    Autoproteolysis in hedgehog protein biogenesis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-02
    Description: Extracellular signaling proteins encoded by the hedgehog (hh) multigene family are responsible for the patterning of a variety of embryonic structures in vertebrates and invertebrates. The Drosophila hh gene has now been shown to generate two predominant protein species that are derived by an internal autoproteolytic cleavage of a larger precursor. Mutations that reduced the efficiency of autoproteolysis in vitro diminished precursor cleavage in vivo and also impaired the signaling and patterning activities of the HH protein. The two HH protein species exhibited distinctive biochemical properties and tissue distribution, and these differences suggest a mechanism that could account for the long- and short-range signaling activities of HH in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, J J -- Ekker, S C -- von Kessler, D P -- Porter, J A -- Sun, B I -- Beachy, P A -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1528-37.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular Biology and Genetics, Johns Hopkins School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985023" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-04-20
    Description: A series of peptide derivatives based on the transition-state mimetic concept has been designed that inhibit the proteinase from the human immunodeficiency virus (HIV). The more active compounds inhibit both HIV-1 and HIV-2 proteinases in the nanomolar range with little effect at 10 micromolar against the structurally related human aspartic proteinases. Proteolytic cleavage of the HIV-1 gag polyprotein (p55) to the viral structural protein p24 was inhibited in chronically infected CEM cells. Antiviral activity was observed in the nanomolar range (with one compound active below 10 nanomolar) in three different cell systems, as assessed by p24 antigen and syncytium formation. Cytotoxicity was not detected at 10 and 5 micromolar in C8166 and JM cells, respectively, indicating a high therapeutic index for this new class of HIV proteinase inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, N A -- Martin, J A -- Kinchington, D -- Broadhurst, A V -- Craig, J C -- Duncan, I B -- Galpin, S A -- Handa, B K -- Kay, J -- Krohn, A -- New York, N.Y. -- Science. 1990 Apr 20;248(4953):358-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Roche Products Ltd., Hertfordshire, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2183354" target="_blank"〉PubMed〈/a〉

    Pandemic potential of a strain of influenza A (H1N1): early findings (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-13
    Description: A novel influenza A (H1N1) virus has spread rapidly across the globe. Judging its pandemic potential is difficult with limited data, but nevertheless essential to inform appropriate health responses. By analyzing the outbreak in Mexico, early data on international spread, and viral genetic diversity, we make an early assessment of transmissibility and severity. Our estimates suggest that 23,000 (range 6000 to 32,000) individuals had been infected in Mexico by late April, giving an estimated case fatality ratio (CFR) of 0.4% (range: 0.3 to 1.8%) based on confirmed and suspected deaths reported to that time. In a community outbreak in the small community of La Gloria, Veracruz, no deaths were attributed to infection, giving an upper 95% bound on CFR of 0.6%. Thus, although substantial uncertainty remains, clinical severity appears less than that seen in the 1918 influenza pandemic but comparable with that seen in the 1957 pandemic. Clinical attack rates in children in La Gloria were twice that in adults (〈15 years of age: 61%; 〉/=15 years: 29%). Three different epidemiological analyses gave basic reproduction number (R0) estimates in the range of 1.4 to 1.6, whereas a genetic analysis gave a central estimate of 1.2. This range of values is consistent with 14 to 73 generations of human-to-human transmission having occurred in Mexico to late April. Transmissibility is therefore substantially higher than that of seasonal flu, and comparable with lower estimates of R0 obtained from previous influenza pandemics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3735127/" 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/PMC3735127/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fraser, Christophe -- Donnelly, Christl A -- Cauchemez, Simon -- Hanage, William P -- Van Kerkhove, Maria D -- Hollingsworth, T Deirdre -- Griffin, Jamie -- Baggaley, Rebecca F -- Jenkins, Helen E -- Lyons, Emily J -- Jombart, Thibaut -- Hinsley, Wes R -- Grassly, Nicholas C -- Balloux, Francois -- Ghani, Azra C -- Ferguson, Neil M -- Rambaut, Andrew -- Pybus, Oliver G -- Lopez-Gatell, Hugo -- Alpuche-Aranda, Celia M -- Chapela, Ietza Bojorquez -- Zavala, Ethel Palacios -- Guevara, Dulce Ma Espejo -- Checchi, Francesco -- Garcia, Erika -- Hugonnet, Stephane -- Roth, Cathy -- WHO Rapid Pandemic Assessment Collaboration -- G0600719/Medical Research Council/United Kingdom -- GR082623MA/Wellcome Trust/United Kingdom -- U54 GM088491/GM/NIGMS NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1557-61. doi: 10.1126/science.1176062.

    Draxin, a repulsive guidance protein for spinal cord and forebrain commissures (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-01-20
    Description: Axon guidance proteins are critical for the correct wiring of the nervous system during development. Several axon guidance cues and their family members have been well characterized. More unidentified axon guidance cues are assumed to participate in the formation of the extremely complex nervous system. We identified a secreted protein, draxin, that shares no homology with known guidance cues. Draxin inhibited or repelled neurite outgrowth from dorsal spinal cord and cortical explants in vitro. Ectopically expressed draxin inhibited growth or caused misrouting of chick spinal cord commissural axons in vivo. draxin knockout mice showed defasciculation of spinal cord commissural axons and absence of all forebrain commissures. Thus, draxin is a previously unknown chemorepulsive axon guidance molecule required for the development of spinal cord and forebrain commissures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Islam, Shahidul M -- Shinmyo, Yohei -- Okafuji, Tatsuya -- Su, Yuhong -- Naser, Iftekhar Bin -- Ahmed, Giasuddin -- Zhang, Sanbing -- Chen, Sandy -- Ohta, Kunimasa -- Kiyonari, Hiroshi -- Abe, Takaya -- Tanaka, Satomi -- Nishinakamura, Ryuichi -- Terashima, Toshio -- Kitamura, Toshio -- Tanaka, Hideaki -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):388-93. doi: 10.1126/science.1165187.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Developmental Neurobiology, Graduate School of Medical Sciences, Kumamoto University, 1-1-1 Honjo, Kumamoto 860-8556, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19150847" target="_blank"〉PubMed〈/a〉
