    Paramyxovirus V proteins disrupt the fold of the RNA sensor MDA5 to inhibit antiviral signaling (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-01-19
    Beschreibung: The retinoic acid-inducible gene I (RIG-I)-like receptor (RLR) melanoma differentiation-associated protein 5 (MDA5) senses cytoplasmic viral RNA and activates antiviral innate immunity. To reveal how paramyxoviruses counteract this response, we determined the crystal structure of the MDA5 adenosine 5'-triphosphate (ATP)-hydrolysis domain in complex with the viral inhibitor V protein. The V protein unfolded the ATP-hydrolysis domain of MDA5 via a beta-hairpin motif and recognized a structural motif of MDA5 that is normally buried in the conserved helicase fold. This leads to disruption of the MDA5 ATP-hydrolysis site and prevention of RNA-bound MDA5 filament formation. The structure explains why V proteins inactivate MDA5, but not RIG-I, and mutating only two amino acids in RIG-I induces robust V protein binding. Our results suggest an inhibition mechanism of RLR signalosome formation by unfolding of receptor and inhibitor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Motz, Carina -- Schuhmann, Kerstin Monika -- Kirchhofer, Axel -- Moldt, Manuela -- Witte, Gregor -- Conzelmann, Karl-Klaus -- Hopfner, Karl-Peter -- U19AI083025/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 8;339(6120):690-3. doi: 10.1126/science.1230949.

    Identification of a colonial chordate histocompatibility gene (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-07-28
    Beschreibung: Histocompatibility is the basis by which multicellular organisms of the same species distinguish self from nonself. Relatively little is known about the mechanisms underlying histocompatibility reactions in lower organisms. Botryllus schlosseri is a colonial urochordate, a sister group of vertebrates, that exhibits a genetically determined natural transplantation reaction, whereby self-recognition between colonies leads to formation of parabionts with a common vasculature, whereas rejection occurs between incompatible colonies. Using genetically defined lines, whole-transcriptome sequencing, and genomics, we identified a single gene that encodes self-nonself and determines "graft" outcomes in this organism. This gene is significantly up-regulated in colonies poised to undergo fusion and/or rejection, is highly expressed in the vasculature, and is functionally linked to histocompatibility outcomes. These findings establish a platform for advancing the science of allorecognition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3810301/" 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/PMC3810301/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Voskoboynik, Ayelet -- Newman, Aaron M -- Corey, Daniel M -- Sahoo, Debashis -- Pushkarev, Dmitry -- Neff, Norma F -- Passarelli, Benedetto -- Koh, Winston -- Ishizuka, Katherine J -- Palmeri, Karla J -- Dimov, Ivan K -- Keasar, Chen -- Fan, H Christina -- Mantalas, Gary L -- Sinha, Rahul -- Penland, Lolita -- Quake, Stephen R -- Weissman, Irving L -- 1R01AG037968/AG/NIA NIH HHS/ -- 1R56AI089968/AI/NIAID NIH HHS/ -- K12 HL087746/HL/NHLBI NIH HHS/ -- K99 CA151673/CA/NCI NIH HHS/ -- K99CA151673-01A1/CA/NCI NIH HHS/ -- R01 AG037968/AG/NIA NIH HHS/ -- R01 GM100315/GM/NIGMS NIH HHS/ -- R01GM100315/GM/NIGMS NIH HHS/ -- R56 AI089968/AI/NIAID NIH HHS/ -- T32 CA009302/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Jul 26;341(6144):384-7. doi: 10.1126/science.1238036.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Stem Cell Biology and Regenerative Medicine, Stanford University School of Medicine, Stanford, CA 94305, USA. ayeletv@stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23888037" target="_blank"〉PubMed〈/a〉

    Complete mitochondrial genomes of ancient canids suggest a European origin of domestic dogs (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-11-16
    Beschreibung: The geographic and temporal origins of the domestic dog remain controversial, as genetic data suggest a domestication process in East Asia beginning 15,000 years ago, whereas the oldest doglike fossils are found in Europe and Siberia and date to 〉30,000 years ago. We analyzed the mitochondrial genomes of 18 prehistoric canids from Eurasia and the New World, along with a comprehensive panel of modern dogs and wolves. The mitochondrial genomes of all modern dogs are phylogenetically most closely related to either ancient or modern canids of Europe. Molecular dating suggests an onset of domestication there 18,800 to 32,100 years ago. These findings imply that domestic dogs are the culmination of a process that initiated with European hunter-gatherers and the canids with whom they interacted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thalmann, O -- Shapiro, B -- Cui, P -- Schuenemann, V J -- Sawyer, S K -- Greenfield, D L -- Germonpre, M B -- Sablin, M V -- Lopez-Giraldez, F -- Domingo-Roura, X -- Napierala, H -- Uerpmann, H-P -- Loponte, D M -- Acosta, A A -- Giemsch, L -- Schmitz, R W -- Worthington, B -- Buikstra, J E -- Druzhkova, A -- Graphodatsky, A S -- Ovodov, N D -- Wahlberg, N -- Freedman, A H -- Schweizer, R M -- Koepfli, K-P -- Leonard, J A -- Meyer, M -- Krause, J -- Paabo, S -- Green, R E -- Wayne, R K -- New York, N.Y. -- Science. 2013 Nov 15;342(6160):871-4. doi: 10.1126/science.1243650.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Section of Genetics and Physiology, University of Turku, Itainen Pitkakatu 4, 20014 Turku, Finland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24233726" target="_blank"〉PubMed〈/a〉

    Structure of parkin reveals mechanisms for ubiquitin ligase activation (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-05-11
    Beschreibung: Mutations in the PARK2 (parkin) gene are responsible for an autosomal recessive form of Parkinson's disease. The parkin protein is a RING-in-between-RING E3 ubiquitin ligase that exhibits low basal activity. We describe the crystal structure of full-length rat parkin. The structure shows parkin in an autoinhibited state and provides insight into how it is activated. RING0 occludes the ubiquitin acceptor site Cys(431) in RING2, whereas a repressor element of parkin binds RING1 and blocks its E2-binding site. Mutations that disrupted these inhibitory interactions activated parkin both in vitro and in cells. Parkin is neuroprotective, and these findings may provide a structural and mechanistic framework for enhancing parkin activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trempe, Jean-Francois -- Sauve, Veronique -- Grenier, Karl -- Seirafi, Marjan -- Tang, Matthew Y -- Menade, Marie -- Al-Abdul-Wahid, Sameer -- Krett, Jonathan -- Wong, Kathy -- Kozlov, Guennadi -- Nagar, Bhushan -- Fon, Edward A -- Gehring, Kalle -- MOP-14219/Canadian Institutes of Health Research/Canada -- MOP-62714/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2013 Jun 21;340(6139):1451-5. doi: 10.1126/science.1237908.

    The genome of the ctenophore Mnemiopsis leidyi and its implications for cell type evolution (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-12-18
    Beschreibung: An understanding of ctenophore biology is critical for reconstructing events that occurred early in animal evolution. Toward this goal, we have sequenced, assembled, and annotated the genome of the ctenophore Mnemiopsis leidyi. Our phylogenomic analyses of both amino acid positions and gene content suggest that ctenophores rather than sponges are the sister lineage to all other animals. Mnemiopsis lacks many of the genes found in bilaterian mesodermal cell types, suggesting that these cell types evolved independently. The set of neural genes in Mnemiopsis is similar to that of sponges, indicating that sponges may have lost a nervous system. These results present a newly supported view of early animal evolution that accounts for major losses and/or gains of sophisticated cell types, including nerve and muscle cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3920664/" 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/PMC3920664/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ryan, Joseph F -- Pang, Kevin -- Schnitzler, Christine E -- Nguyen, Anh-Dao -- Moreland, R Travis -- Simmons, David K -- Koch, Bernard J -- Francis, Warren R -- Havlak, Paul -- NISC Comparative Sequencing Program -- Smith, Stephen A -- Putnam, Nicholas H -- Haddock, Steven H D -- Dunn, Casey W -- Wolfsberg, Tyra G -- Mullikin, James C -- Martindale, Mark Q -- Baxevanis, Andreas D -- ZIA HG000140-13/Intramural NIH HHS/ -- ZIA HG000140-14/Intramural NIH HHS/ -- ZIA HG000140-15/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 Dec 13;342(6164):1242592. doi: 10.1126/science.1242592.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genome Technology Branch, Division of Intramural Research, National Human Genome Research Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24337300" target="_blank"〉PubMed〈/a〉

    Mechanisms of age-dependent response to winter temperature in perennial flowering of Arabis alpina (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-06-01
    Beschreibung: Perennial plants live for more than 1 year and flower only after an extended vegetative phase. We used Arabis alpina, a perennial relative of annual Arabidopsis thaliana, to study how increasing age and exposure to winter cold (vernalization) coordinate to establish competence to flower. We show that the APETALA2 transcription factor, a target of microRNA miR172, prevents flowering before vernalization. Additionally, miR156 levels decline as A. alpina ages, causing increased production of SPL (SQUAMOSA PROMOTER BINDING PROTEIN LIKE) transcription factors and ensuring that flowering occurs in response to cold. The age at which plants respond to vernalization can be altered by manipulating miR156 levels. Although miR156 and miR172 levels are uncoupled in A. alpina, miR156 abundance represents the timer controlling age-dependent flowering responses to cold.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bergonzi, Sara -- Albani, Maria C -- Ver Loren van Themaat, Emiel -- Nordstrom, Karl J V -- Wang, Renhou -- Schneeberger, Korbinian -- Moerland, Perry D -- Coupland, George -- New York, N.Y. -- Science. 2013 May 31;340(6136):1094-7. doi: 10.1126/science.1234116.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Plant Breeding Research, Cologne, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23723236" target="_blank"〉PubMed〈/a〉

    Ancient DNA reveals key stages in the formation of central European mitochondrial genetic diversity (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-10-12
    Beschreibung: The processes that shaped modern European mitochondrial DNA (mtDNA) variation remain unclear. The initial peopling by Palaeolithic hunter-gatherers ~42,000 years ago and the immigration of Neolithic farmers into Europe ~8000 years ago appear to have played important roles but do not explain present-day mtDNA diversity. We generated mtDNA profiles of 364 individuals from prehistoric cultures in Central Europe to perform a chronological study, spanning the Early Neolithic to the Early Bronze Age (5500 to 1550 calibrated years before the common era). We used this transect through time to identify four marked shifts in genetic composition during the Neolithic period, revealing a key role for Late Neolithic cultures in shaping modern Central European genetic diversity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4039305/" 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/PMC4039305/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brandt, Guido -- Haak, Wolfgang -- Adler, Christina J -- Roth, Christina -- Szecsenyi-Nagy, Anna -- Karimnia, Sarah -- Moller-Rieker, Sabine -- Meller, Harald -- Ganslmeier, Robert -- Friederich, Susanne -- Dresely, Veit -- Nicklisch, Nicole -- Pickrell, Joseph K -- Sirocko, Frank -- Reich, David -- Cooper, Alan -- Alt, Kurt W -- Genographic Consortium -- R01 GM100233/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Oct 11;342(6155):257-61. doi: 10.1126/science.1241844.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Anthropology, Johannes Gutenberg University of Mainz, Mainz, Germany. brandtg@uni-mainz.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24115443" target="_blank"〉PubMed〈/a〉

    A strategy for modulation of enzymes in the ubiquitin system (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-01-05
    Beschreibung: The ubiquitin system regulates virtually all aspects of cellular function. We report a method to target the myriad enzymes that govern ubiquitination of protein substrates. We used massively diverse combinatorial libraries of ubiquitin variants to develop inhibitors of four deubiquitinases (DUBs) and analyzed the DUB-inhibitor complexes with crystallography. We extended the selection strategy to the ubiquitin conjugating (E2) and ubiquitin ligase (E3) enzymes and found that ubiquitin variants can also enhance enzyme activity. Last, we showed that ubiquitin variants can bind selectively to ubiquitin-binding domains. Ubiquitin variants exhibit selective function in cells and thus enable orthogonal modulation of specific enzymatic steps in the ubiquitin system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3815447/" 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/PMC3815447/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ernst, Andreas -- Avvakumov, George -- Tong, Jiefei -- Fan, Yihui -- Zhao, Yanling -- Alberts, Philipp -- Persaud, Avinash -- Walker, John R -- Neculai, Ana-Mirela -- Neculai, Dante -- Vorobyov, Andrew -- Garg, Pankaj -- Beatty, Linda -- Chan, Pak-Kei -- Juang, Yu-Chi -- Landry, Marie-Claude -- Yeh, Christina -- Zeqiraj, Elton -- Karamboulas, Konstantina -- Allali-Hassani, Abdellah -- Vedadi, Masoud -- Tyers, Mike -- Moffat, Jason -- Sicheri, Frank -- Pelletier, Laurence -- Durocher, Daniel -- Raught, Brian -- Rotin, Daniela -- Yang, Jianhua -- Moran, Michael F -- Dhe-Paganon, Sirano -- Sidhu, Sachdev S -- 092076/Wellcome Trust/United Kingdom -- 092381/Wellcome Trust/United Kingdom -- 1R01NS072420-01/Canadian Institutes of Health Research/Canada -- MOP-102536/Canadian Institutes of Health Research/Canada -- MOP-111149/Canadian Institutes of Health Research/Canada -- MOP-13494/Canadian Institutes of Health Research/Canada -- MOP-57795/Canadian Institutes of Health Research/Canada -- R01 NS072420/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 1;339(6119):590-5. doi: 10.1126/science.1230161.

    EMRE is an essential component of the mitochondrial calcium uniporter complex (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-11-16
    Beschreibung: The mitochondrial uniporter is a highly selective calcium channel in the organelle's inner membrane. Its molecular components include the EF-hand-containing calcium-binding proteins mitochondrial calcium uptake 1 (MICU1) and MICU2 and the pore-forming subunit mitochondrial calcium uniporter (MCU). We sought to achieve a full molecular characterization of the uniporter holocomplex (uniplex). Quantitative mass spectrometry of affinity-purified uniplex recovered MICU1 and MICU2, MCU and its paralog MCUb, and essential MCU regulator (EMRE), a previously uncharacterized protein. EMRE is a 10-kilodalton, metazoan-specific protein with a single transmembrane domain. In its absence, uniporter channel activity was lost despite intact MCU expression and oligomerization. EMRE was required for the interaction of MCU with MICU1 and MICU2. Hence, EMRE is essential for in vivo uniporter current and additionally bridges the calcium-sensing role of MICU1 and MICU2 with the calcium-conducting role of MCU.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4091629/" 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/PMC4091629/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sancak, Yasemin -- Markhard, Andrew L -- Kitami, Toshimori -- Kovacs-Bogdan, Erika -- Kamer, Kimberli J -- Udeshi, Namrata D -- Carr, Steven A -- Chaudhuri, Dipayan -- Clapham, David E -- Li, Andrew A -- Calvo, Sarah E -- Goldberger, Olga -- Mootha, Vamsi K -- DK080261/DK/NIDDK NIH HHS/ -- F32 HL107021/HL/NHLBI NIH HHS/ -- F32HL107021/HL/NHLBI NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- R24 DK080261/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Dec 13;342(6164):1379-82. doi: 10.1126/science.1242993.

    Beschreibung: The prefusion state of respiratory syncytial virus (RSV) fusion (F) glycoprotein is the target of most RSV-neutralizing activity in human sera, but its metastability has hindered characterization. To overcome this obstacle, we identified prefusion-specific antibodies that were substantially more potent than the prophylactic antibody palivizumab. The cocrystal structure for one of these antibodies, D25, in complex with the F glycoprotein revealed D25 to lock F in its prefusion state by binding to a quaternary epitope at the trimer apex. Electron microscopy showed that two other antibodies, AM22 and 5C4, also bound to the newly identified site of vulnerability, which we named antigenic site O. These studies should enable design of improved vaccine antigens and define new targets for passive prevention of RSV-induced disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4459498/" 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/PMC4459498/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McLellan, Jason S -- Chen, Man -- Leung, Sherman -- Graepel, Kevin W -- Du, Xiulian -- Yang, Yongping -- Zhou, Tongqing -- Baxa, Ulrich -- Yasuda, Etsuko -- Beaumont, Tim -- Kumar, Azad -- Modjarrad, Kayvon -- Zheng, Zizheng -- Zhao, Min -- Xia, Ningshao -- Kwong, Peter D -- Graham, Barney S -- ZIA AI005024-11/Intramural NIH HHS/ -- ZIA AI005061-10/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 May 31;340(6136):1113-7. doi: 10.1126/science.1234914.
