    The African coelacanth genome provides insights into tetrapod evolution (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-04-20
    Description: The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the African coelacanth, Latimeria chalumnae. Through a phylogenomic analysis, we conclude that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Coelacanth protein-coding genes are significantly more slowly evolving than those of tetrapods, unlike other genomic features. Analyses of changes in genes and regulatory elements during the vertebrate adaptation to land highlight genes involved in immunity, nitrogen excretion and the development of fins, tail, ear, eye, brain and olfaction. Functional assays of enhancers involved in the fin-to-limb transition and in the emergence of extra-embryonic tissues show the importance of the coelacanth genome as a blueprint for understanding tetrapod evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3633110/" 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/PMC3633110/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amemiya, Chris T -- Alfoldi, Jessica -- Lee, Alison P -- Fan, Shaohua -- Philippe, Herve -- Maccallum, Iain -- Braasch, Ingo -- Manousaki, Tereza -- Schneider, Igor -- Rohner, Nicolas -- Organ, Chris -- Chalopin, Domitille -- Smith, Jeramiah J -- Robinson, Mark -- Dorrington, Rosemary A -- Gerdol, Marco -- Aken, Bronwen -- Biscotti, Maria Assunta -- Barucca, Marco -- Baurain, Denis -- Berlin, Aaron M -- Blatch, Gregory L -- Buonocore, Francesco -- Burmester, Thorsten -- Campbell, Michael S -- Canapa, Adriana -- Cannon, John P -- Christoffels, Alan -- De Moro, Gianluca -- Edkins, Adrienne L -- Fan, Lin -- Fausto, Anna Maria -- Feiner, Nathalie -- Forconi, Mariko -- Gamieldien, Junaid -- Gnerre, Sante -- Gnirke, Andreas -- Goldstone, Jared V -- Haerty, Wilfried -- Hahn, Mark E -- Hesse, Uljana -- Hoffmann, Steve -- Johnson, Jeremy -- Karchner, Sibel I -- Kuraku, Shigehiro -- Lara, Marcia -- Levin, Joshua Z -- Litman, Gary W -- Mauceli, Evan -- Miyake, Tsutomu -- Mueller, M Gail -- Nelson, David R -- Nitsche, Anne -- Olmo, Ettore -- Ota, Tatsuya -- Pallavicini, Alberto -- Panji, Sumir -- Picone, Barbara -- Ponting, Chris P -- Prohaska, Sonja J -- Przybylski, Dariusz -- Saha, Nil Ratan -- Ravi, Vydianathan -- Ribeiro, Filipe J -- Sauka-Spengler, Tatjana -- Scapigliati, Giuseppe -- Searle, Stephen M J -- Sharpe, Ted -- Simakov, Oleg -- Stadler, Peter F -- Stegeman, John J -- Sumiyama, Kenta -- Tabbaa, Diana -- Tafer, Hakim -- Turner-Maier, Jason -- van Heusden, Peter -- White, Simon -- Williams, Louise -- Yandell, Mark -- Brinkmann, Henner -- Volff, Jean-Nicolas -- Tabin, Clifford J -- Shubin, Neil -- Schartl, Manfred -- Jaffe, David B -- Postlethwait, John H -- Venkatesh, Byrappa -- Di Palma, Federica -- Lander, Eric S -- Meyer, Axel -- Lindblad-Toh, Kerstin -- 095908/Wellcome Trust/United Kingdom -- MC_U137761446/Medical Research Council/United Kingdom -- P42 ES007381/ES/NIEHS NIH HHS/ -- R01 ES006272/ES/NIEHS NIH HHS/ -- R01 HG003474/HG/NHGRI NIH HHS/ -- R01 OD011116/OD/NIH HHS/ -- R24 OD011199/OD/NIH HHS/ -- R24 RR032670/RR/NCRR NIH HHS/ -- R37 HD032443/HD/NICHD NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- England -- Nature. 2013 Apr 18;496(7445):311-6. doi: 10.1038/nature12027.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Program, Benaroya Research Institute, Seattle, Washington 98101, USA. camemiya@benaroyaresearch.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23598338" target="_blank"〉PubMed〈/a〉

    Co-evolution of a broadly neutralizing HIV-1 antibody and founder virus (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-04-05
    Description: Current human immunodeficiency virus-1 (HIV-1) vaccines elicit strain-specific neutralizing antibodies. However, cross-reactive neutralizing antibodies arise in approximately 20% of HIV-1-infected individuals, and details of their generation could provide a blueprint for effective vaccination. Here we report the isolation, evolution and structure of a broadly neutralizing antibody from an African donor followed from the time of infection. The mature antibody, CH103, neutralized approximately 55% of HIV-1 isolates, and its co-crystal structure with the HIV-1 envelope protein gp120 revealed a new loop-based mechanism of CD4-binding-site recognition. Virus and antibody gene sequencing revealed concomitant virus evolution and antibody maturation. Notably, the unmutated common ancestor of the CH103 lineage avidly bound the transmitted/founder HIV-1 envelope glycoprotein, and evolution of antibody neutralization breadth was preceded by extensive viral diversification in and near the CH103 epitope. These data determine the viral and antibody evolution leading to induction of a lineage of HIV-1 broadly neutralizing antibodies, and provide insights into strategies to elicit similar antibodies by vaccination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3637846/" 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/PMC3637846/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liao, Hua-Xin -- Lynch, Rebecca -- Zhou, Tongqing -- Gao, Feng -- Alam, S Munir -- Boyd, Scott D -- Fire, Andrew Z -- Roskin, Krishna M -- Schramm, Chaim A -- Zhang, Zhenhai -- Zhu, Jiang -- Shapiro, Lawrence -- NISC Comparative Sequencing Program -- Mullikin, James C -- Gnanakaran, S -- Hraber, Peter -- Wiehe, Kevin -- Kelsoe, Garnett -- Yang, Guang -- Xia, Shi-Mao -- Montefiori, David C -- Parks, Robert -- Lloyd, Krissey E -- Scearce, Richard M -- Soderberg, Kelly A -- Cohen, Myron -- Kamanga, Gift -- Louder, Mark K -- Tran, Lillian M -- Chen, Yue -- Cai, Fangping -- Chen, Sheri -- Moquin, Stephanie -- Du, Xiulian -- Joyce, M Gordon -- Srivatsan, Sanjay -- Zhang, Baoshan -- Zheng, Anqi -- Shaw, George M -- Hahn, Beatrice H -- Kepler, Thomas B -- Korber, Bette T M -- Kwong, Peter D -- Mascola, John R -- Haynes, Barton F -- AI067854/AI/NIAID NIH HHS/ -- AI100645/AI/NIAID NIH HHS/ -- P30 AI050410/AI/NIAID NIH HHS/ -- UM1 AI100645/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2013 Apr 25;496(7446):469-76. doi: 10.1038/nature12053.

    High-level semi-synthetic production of the potent antimalarial artemisinin (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-04-12
    Description: In 2010 there were more than 200 million cases of malaria, and at least 655,000 deaths. The World Health Organization has recommended artemisinin-based combination therapies (ACTs) for the treatment of uncomplicated malaria caused by the parasite Plasmodium falciparum. Artemisinin is a sesquiterpene endoperoxide with potent antimalarial properties, produced by the plant Artemisia annua. However, the supply of plant-derived artemisinin is unstable, resulting in shortages and price fluctuations, complicating production planning by ACT manufacturers. A stable source of affordable artemisinin is required. Here we use synthetic biology to develop strains of Saccharomyces cerevisiae (baker's yeast) for high-yielding biological production of artemisinic acid, a precursor of artemisinin. Previous attempts to produce commercially relevant concentrations of artemisinic acid were unsuccessful, allowing production of only 1.6 grams per litre of artemisinic acid. Here we demonstrate the complete biosynthetic pathway, including the discovery of a plant dehydrogenase and a second cytochrome that provide an efficient biosynthetic route to artemisinic acid, with fermentation titres of 25 grams per litre of artemisinic acid. Furthermore, we have developed a practical, efficient and scalable chemical process for the conversion of artemisinic acid to artemisinin using a chemical source of singlet oxygen, thus avoiding the need for specialized photochemical equipment. The strains and processes described here form the basis of a viable industrial process for the production of semi-synthetic artemisinin to stabilize the supply of artemisinin for derivatization into active pharmaceutical ingredients (for example, artesunate) for incorporation into ACTs. Because all intellectual property rights have been provided free of charge, this technology has the potential to increase provision of first-line antimalarial treatments to the developing world at a reduced average annual price.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paddon, C J -- Westfall, P J -- Pitera, D J -- Benjamin, K -- Fisher, K -- McPhee, D -- Leavell, M D -- Tai, A -- Main, A -- Eng, D -- Polichuk, D R -- Teoh, K H -- Reed, D W -- Treynor, T -- Lenihan, J -- Fleck, M -- Bajad, S -- Dang, G -- Dengrove, D -- Diola, D -- Dorin, G -- Ellens, K W -- Fickes, S -- Galazzo, J -- Gaucher, S P -- Geistlinger, T -- Henry, R -- Hepp, M -- Horning, T -- Iqbal, T -- Jiang, H -- Kizer, L -- Lieu, B -- Melis, D -- Moss, N -- Regentin, R -- Secrest, S -- Tsuruta, H -- Vazquez, R -- Westblade, L F -- Xu, L -- Yu, M -- Zhang, Y -- Zhao, L -- Lievense, J -- Covello, P S -- Keasling, J D -- Reiling, K K -- Renninger, N S -- Newman, J D -- England -- Nature. 2013 Apr 25;496(7446):528-32. doi: 10.1038/nature12051.

    Evidence for a common mechanism of SIRT1 regulation by allosteric activators (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-09
    Description: A molecule that treats multiple age-related diseases would have a major impact on global health and economics. The SIRT1 deacetylase has drawn attention in this regard as a target for drug design. Yet controversy exists around the mechanism of sirtuin-activating compounds (STACs). We found that specific hydrophobic motifs found in SIRT1 substrates such as PGC-1alpha and FOXO3a facilitate SIRT1 activation by STACs. A single amino acid in SIRT1, Glu(230), located in a structured N-terminal domain, was critical for activation by all previously reported STAC scaffolds and a new class of chemically distinct activators. In primary cells reconstituted with activation-defective SIRT1, the metabolic effects of STACs were blocked. Thus, SIRT1 can be directly activated through an allosteric mechanism common to chemically diverse STACs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3799917/" 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/PMC3799917/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hubbard, Basil P -- Gomes, Ana P -- Dai, Han -- Li, Jun -- Case, April W -- Considine, Thomas -- Riera, Thomas V -- Lee, Jessica E -- E, Sook Yen -- Lamming, Dudley W -- Pentelute, Bradley L -- Schuman, Eli R -- Stevens, Linda A -- Ling, Alvin J Y -- Armour, Sean M -- Michan, Shaday -- Zhao, Huizhen -- Jiang, Yong -- Sweitzer, Sharon M -- Blum, Charles A -- Disch, Jeremy S -- Ng, Pui Yee -- Howitz, Konrad T -- Rolo, Anabela P -- Hamuro, Yoshitomo -- Moss, Joel -- Perni, Robert B -- Ellis, James L -- Vlasuk, George P -- Sinclair, David A -- P01 AG027916/AG/NIA NIH HHS/ -- R01 AG019719/AG/NIA NIH HHS/ -- R01 AG028730/AG/NIA NIH HHS/ -- R37 AG028730/AG/NIA NIH HHS/ -- ZIA HL000659-20/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 Mar 8;339(6124):1216-9. doi: 10.1126/science.1231097.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23471411" target="_blank"〉PubMed〈/a〉

    A compendium of RNA-binding motifs for decoding gene regulation (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-07-13
    Description: RNA-binding proteins are key regulators of gene expression, yet only a small fraction have been functionally characterized. Here we report a systematic analysis of the RNA motifs recognized by RNA-binding proteins, encompassing 205 distinct genes from 24 diverse eukaryotes. The sequence specificities of RNA-binding proteins display deep evolutionary conservation, and the recognition preferences for a large fraction of metazoan RNA-binding proteins can thus be inferred from their RNA-binding domain sequence. The motifs that we identify in vitro correlate well with in vivo RNA-binding data. Moreover, we can associate them with distinct functional roles in diverse types of post-transcriptional regulation, enabling new insights into the functions of RNA-binding proteins both in normal physiology and in human disease. These data provide an unprecedented overview of RNA-binding proteins and their targets, and constitute an invaluable resource for determining post-transcriptional regulatory mechanisms in eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3929597/" 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/PMC3929597/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ray, Debashish -- Kazan, Hilal -- Cook, Kate B -- Weirauch, Matthew T -- Najafabadi, Hamed S -- Li, Xiao -- Gueroussov, Serge -- Albu, Mihai -- Zheng, Hong -- Yang, Ally -- Na, Hong -- Irimia, Manuel -- Matzat, Leah H -- Dale, Ryan K -- Smith, Sarah A -- Yarosh, Christopher A -- Kelly, Seth M -- Nabet, Behnam -- Mecenas, Desirea -- Li, Weimin -- Laishram, Rakesh S -- Qiao, Mei -- Lipshitz, Howard D -- Piano, Fabio -- Corbett, Anita H -- Carstens, Russ P -- Frey, Brendan J -- Anderson, Richard A -- Lynch, Kristen W -- Penalva, Luiz O F -- Lei, Elissa P -- Fraser, Andrew G -- Blencowe, Benjamin J -- Morris, Quaid D -- Hughes, Timothy R -- 1R01HG00570/HG/NHGRI NIH HHS/ -- DK015602-05/DK/NIDDK NIH HHS/ -- MOP-125894/Canadian Institutes of Health Research/Canada -- MOP-14409/Canadian Institutes of Health Research/Canada -- MOP-49451/Canadian Institutes of Health Research/Canada -- MOP-67011/Canadian Institutes of Health Research/Canada -- MOP-93671/Canadian Institutes of Health Research/Canada -- P30 CA014520/CA/NCI NIH HHS/ -- R01 CA104708/CA/NCI NIH HHS/ -- R01 GM051968/GM/NIGMS NIH HHS/ -- R01 GM084034/GM/NIGMS NIH HHS/ -- R01 HG005700/HG/NHGRI NIH HHS/ -- R01GM084034/GM/NIGMS NIH HHS/ -- T32 GM008061/GM/NIGMS NIH HHS/ -- Z01 DK015602-01/Intramural NIH HHS/ -- England -- Nature. 2013 Jul 11;499(7457):172-7. doi: 10.1038/nature12311.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Donnelly Centre, University of Toronto, Toronto M5S 3E1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23846655" target="_blank"〉PubMed〈/a〉

    Mutations in prion-like domains in hnRNPA2B1 and hnRNPA1 cause multisystem proteinopathy and ALS (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-03-05
    Description: Algorithms designed to identify canonical yeast prions predict that around 250 human proteins, including several RNA-binding proteins associated with neurodegenerative disease, harbour a distinctive prion-like domain (PrLD) enriched in uncharged polar amino acids and glycine. PrLDs in RNA-binding proteins are essential for the assembly of ribonucleoprotein granules. However, the interplay between human PrLD function and disease is not understood. Here we define pathogenic mutations in PrLDs of heterogeneous nuclear ribonucleoproteins (hnRNPs) A2B1 and A1 in families with inherited degeneration affecting muscle, brain, motor neuron and bone, and in one case of familial amyotrophic lateral sclerosis. Wild-type hnRNPA2 (the most abundant isoform of hnRNPA2B1) and hnRNPA1 show an intrinsic tendency to assemble into self-seeding fibrils, which is exacerbated by the disease mutations. Indeed, the pathogenic mutations strengthen a 'steric zipper' motif in the PrLD, which accelerates the formation of self-seeding fibrils that cross-seed polymerization of wild-type hnRNP. Notably, the disease mutations promote excess incorporation of hnRNPA2 and hnRNPA1 into stress granules and drive the formation of cytoplasmic inclusions in animal models that recapitulate the human pathology. Thus, dysregulated polymerization caused by a potent mutant steric zipper motif in a PrLD can initiate degenerative disease. Related proteins with PrLDs should therefore be considered candidates for initiating and perhaps propagating proteinopathies of muscle, brain, motor neuron and bone.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756911/" 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/PMC3756911/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Hong Joo -- Kim, Nam Chul -- Wang, Yong-Dong -- Scarborough, Emily A -- Moore, Jennifer -- Diaz, Zamia -- MacLea, Kyle S -- Freibaum, Brian -- Li, Songqing -- Molliex, Amandine -- Kanagaraj, Anderson P -- Carter, Robert -- Boylan, Kevin B -- Wojtas, Aleksandra M -- Rademakers, Rosa -- Pinkus, Jack L -- Greenberg, Steven A -- Trojanowski, John Q -- Traynor, Bryan J -- Smith, Bradley N -- Topp, Simon -- Gkazi, Athina-Soragia -- Miller, Jack -- Shaw, Christopher E -- Kottlors, Michael -- Kirschner, Janbernd -- Pestronk, Alan -- Li, Yun R -- Ford, Alice Flynn -- Gitler, Aaron D -- Benatar, Michael -- King, Oliver D -- Kimonis, Virginia E -- Ross, Eric D -- Weihl, Conrad C -- Shorter, James -- Taylor, J Paul -- 089701/Wellcome Trust/United Kingdom -- AG031867/AG/NIA NIH HHS/ -- AG032953/AG/NIA NIH HHS/ -- DP2OD002177/OD/NIH HHS/ -- G0900688/Medical Research Council/United Kingdom -- K02 AG042095/AG/NIA NIH HHS/ -- MC_G1000733/Medical Research Council/United Kingdom -- NS053825/NS/NINDS NIH HHS/ -- NS067354/NS/NINDS NIH HHS/ -- P01 AG032953/AG/NIA NIH HHS/ -- R01 AG031867/AG/NIA NIH HHS/ -- R01 NS053825/NS/NINDS NIH HHS/ -- England -- Nature. 2013 Mar 28;495(7442):467-73. doi: 10.1038/nature11922.

    Influence of HLA-C expression level on HIV control (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-04-06
    Description: A variant upstream of human leukocyte antigen C (HLA-C) shows the most significant genome-wide effect on HIV control in European Americans and is also associated with the level of HLA-C expression. We characterized the differential cell surface expression levels of all common HLA-C allotypes and tested directly for effects of HLA-C expression on outcomes of HIV infection in 5243 individuals. Increasing HLA-C expression was associated with protection against multiple outcomes independently of individual HLA allelic effects in both African and European Americans, regardless of their distinct HLA-C frequencies and linkage relationships with HLA-B and HLA-A. Higher HLA-C expression was correlated with increased likelihood of cytotoxic T lymphocyte responses and frequency of viral escape mutation. In contrast, high HLA-C expression had a deleterious effect in Crohn's disease, suggesting a broader influence of HLA expression levels in human disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3784322/" 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/PMC3784322/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Apps, Richard -- Qi, Ying -- Carlson, Jonathan M -- Chen, Haoyan -- Gao, Xiaojiang -- Thomas, Rasmi -- Yuki, Yuko -- Del Prete, Greg Q -- Goulder, Philip -- Brumme, Zabrina L -- Brumme, Chanson J -- John, Mina -- Mallal, Simon -- Nelson, George -- Bosch, Ronald -- Heckerman, David -- Stein, Judy L -- Soderberg, Kelly A -- Moody, M Anthony -- Denny, Thomas N -- Zeng, Xue -- Fang, Jingyuan -- Moffett, Ashley -- Lifson, Jeffrey D -- Goedert, James J -- Buchbinder, Susan -- Kirk, Gregory D -- Fellay, Jacques -- McLaren, Paul -- Deeks, Steven G -- Pereyra, Florencia -- Walker, Bruce -- Michael, Nelson L -- Weintrob, Amy -- Wolinsky, Steven -- Liao, Wilson -- Carrington, Mary -- 5-M01-RR-00722/RR/NCRR NIH HHS/ -- HHSN261200800001E/CA/NCI NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- K08 AR057763/AR/NIAMS NIH HHS/ -- K08AR057763/AR/NIAMS NIH HHS/ -- K24 AI069994/AI/NIAID NIH HHS/ -- K24AI069994/AI/NIAID NIH HHS/ -- N02-CP-55504/CP/NCI NIH HHS/ -- P30 AI027763/AI/NIAID NIH HHS/ -- P30 AI027767/AI/NIAID NIH HHS/ -- P30 AI027767-24/AI/NIAID NIH HHS/ -- P30 MH62246/MH/NIMH NIH HHS/ -- PG/09/077/27964/British Heart Foundation/United Kingdom -- R01 AI046995/AI/NIAID NIH HHS/ -- R01 AI060460/AI/NIAID NIH HHS/ -- R01 AI087145/AI/NIAID NIH HHS/ -- R01 AR065174/AR/NIAMS NIH HHS/ -- R01-AI046995/AI/NIAID NIH HHS/ -- R01-AI060460/AI/NIAID NIH HHS/ -- R01-DA-04334/DA/NIDA NIH HHS/ -- R01-DA-12568/DA/NIDA NIH HHS/ -- R01-DA04334/DA/NIDA NIH HHS/ -- R01-DA12568/DA/NIDA NIH HHS/ -- R24 AI067039/AI/NIAID NIH HHS/ -- U01-AI-067854/AI/NIAID NIH HHS/ -- U01-AI-35039/AI/NIAID NIH HHS/ -- U01-AI-35040/AI/NIAID NIH HHS/ -- U01-AI-35041/AI/NIAID NIH HHS/ -- U01-AI-35042/AI/NIAID NIH HHS/ -- U01-AI-35043/AI/NIAID NIH HHS/ -- U01-AI-37613/AI/NIAID NIH HHS/ -- U01-AI-37984/AI/NIAID NIH HHS/ -- UL1 RR024131/RR/NCRR NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2013 Apr 5;340(6128):87-91. doi: 10.1126/science.1232685.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer and Inflammation Program, Laboratory of Experimental Immunology, Science Applications International Corporation-Frederick, Inc., Frederick National Laboratory for Cancer Research, Frederick, MD 21702, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23559252" target="_blank"〉PubMed〈/a〉

    Proteolytic elimination of N-myristoyl modifications by the Shigella virulence factor IpaJ (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-03-29
    Description: Protein N-myristoylation is a 14-carbon fatty-acid modification that is conserved across eukaryotic species and occurs on nearly 1% of the cellular proteome. The ability of the myristoyl group to facilitate dynamic protein-protein and protein-membrane interactions (known as the myristoyl switch) makes it an essential feature of many signal transduction systems. Thus pathogenic strategies that facilitate protein demyristoylation would markedly alter the signalling landscape of infected host cells. Here we describe an irreversible mechanism of protein demyristoylation catalysed by invasion plasmid antigen J (IpaJ), a previously uncharacterized Shigella flexneri type III effector protein with cysteine protease activity. A yeast genetic screen for IpaJ substrates identified ADP-ribosylation factor (ARF)1p and ARF2p, small molecular mass GTPases that regulate cargo transport through the Golgi apparatus. Mass spectrometry showed that IpaJ cleaved the peptide bond between N-myristoylated glycine-2 and asparagine-3 of human ARF1, thereby providing a new mechanism for host secretory inhibition by a bacterial pathogen. We further demonstrate that IpaJ cleaves an array of N-myristoylated proteins involved in cellular growth, signal transduction, autophagasome maturation and organelle function. Taken together, these findings show a previously unrecognized pathogenic mechanism for the site-specific elimination of N-myristoyl protein modification.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722872/" 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/PMC3722872/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnaevskiy, Nikolay -- Fox, Thomas G -- Plymire, Daniel A -- Ertelt, James M -- Weigele, Bethany A -- Selyunin, Andrey S -- Way, Sing Sing -- Patrie, Steven M -- Alto, Neal M -- 5T32AI007520/AI/NIAID NIH HHS/ -- R01 AI083359/AI/NIAID NIH HHS/ -- R01 AI087830/AI/NIAID NIH HHS/ -- R01 AI100934/AI/NIAID NIH HHS/ -- R01 GM100486/GM/NIGMS NIH HHS/ -- R01AI083359/AI/NIAID NIH HHS/ -- R01GM100486/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Apr 4;496(7443):106-9. doi: 10.1038/nature12004.

    Immunological and virological mechanisms of vaccine-mediated protection against SIV and HIV (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-12-20
    Description: A major challenge for the development of a highly effective AIDS vaccine is the identification of mechanisms of protective immunity. To address this question, we used a nonhuman primate challenge model with simian immunodeficiency virus (SIV). We show that antibodies to the SIV envelope are necessary and sufficient to prevent infection. Moreover, sequencing of viruses from breakthrough infections revealed selective pressure against neutralization-sensitive viruses; we identified a two-amino-acid signature that alters antigenicity and confers neutralization resistance. A similar signature confers resistance of human immunodeficiency virus (HIV)-1 to neutralization by monoclonal antibodies against variable regions 1 and 2 (V1V2), suggesting that SIV and HIV share a fundamental mechanism of immune escape from vaccine-elicited or naturally elicited antibodies. These analyses provide insight into the limited efficacy seen in HIV vaccine trials.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946913/" 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/PMC3946913/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roederer, Mario -- Keele, Brandon F -- Schmidt, Stephen D -- Mason, Rosemarie D -- Welles, Hugh C -- Fischer, Will -- Labranche, Celia -- Foulds, Kathryn E -- Louder, Mark K -- Yang, Zhi-Yong -- Todd, John-Paul M -- Buzby, Adam P -- Mach, Linh V -- Shen, Ling -- Seaton, Kelly E -- Ward, Brandy M -- Bailer, Robert T -- Gottardo, Raphael -- Gu, Wenjuan -- Ferrari, Guido -- Alam, S Munir -- Denny, Thomas N -- Montefiori, David C -- Tomaras, Georgia D -- Korber, Bette T -- Nason, Martha C -- Seder, Robert A -- Koup, Richard A -- Letvin, Norman L -- Rao, Srinivas S -- Nabel, Gary J -- Mascola, John R -- AI100645/AI/NIAID NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- HHSN27201100016C/PHS HHS/ -- UM1 AI100645/AI/NIAID NIH HHS/ -- Z99 AI999999/Intramural NIH HHS/ -- ZIA AI005019-12/Intramural NIH HHS/ -- England -- Nature. 2014 Jan 23;505(7484):502-8. doi: 10.1038/nature12893.

    A secreted PTEN phosphatase that enters cells to alter signaling and survival (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-06-08
    Description: Phosphatase and tensin homolog on chromosome ten (PTEN) is a tumor suppressor and an antagonist of the phosphoinositide-3 kinase (PI3K) pathway. We identified a 576-amino acid translational variant of PTEN, termed PTEN-Long, that arises from an alternative translation start site 519 base pairs upstream of the ATG initiation sequence, adding 173 N-terminal amino acids to the normal PTEN open reading frame. PTEN-Long is a membrane-permeable lipid phosphatase that is secreted from cells and can enter other cells. As an exogenous agent, PTEN-Long antagonized PI3K signaling and induced tumor cell death in vitro and in vivo. By providing a means to restore a functional tumor-suppressor protein to tumor cells, PTEN-Long may have therapeutic uses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3935617/" 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/PMC3935617/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hopkins, Benjamin D -- Fine, Barry -- Steinbach, Nicole -- Dendy, Meaghan -- Rapp, Zachary -- Shaw, Jacquelyn -- Pappas, Kyrie -- Yu, Jennifer S -- Hodakoski, Cindy -- Mense, Sarah -- Klein, Joshua -- Pegno, Sarah -- Sulis, Maria-Luisa -- Goldstein, Hannah -- Amendolara, Benjamin -- Lei, Liang -- Maurer, Matthew -- Bruce, Jeffrey -- Canoll, Peter -- Hibshoosh, Hanina -- Parsons, Ramon -- 2T32 CA09503/CA/NCI NIH HHS/ -- CA082783/CA/NCI NIH HHS/ -- CA097403/CA/NCI NIH HHS/ -- P01 CA097403/CA/NCI NIH HHS/ -- R01 CA082783/CA/NCI NIH HHS/ -- R01 CA155117/CA/NCI NIH HHS/ -- R01 NS066955/NS/NINDS NIH HHS/ -- R01 NS073610/NS/NINDS NIH HHS/ -- R01NS066955/NS/NINDS NIH HHS/ -- T32 CA009503/CA/NCI NIH HHS/ -- T32 GM008224/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jul 26;341(6144):399-402. doi: 10.1126/science.1234907.
