    MARF1 regulates essential oogenic processes in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-24
    Description: Development of fertilization-competent oocytes depends on integrated processes controlling meiosis, cytoplasmic development, and maintenance of genomic integrity. We show that meiosis arrest female 1 (MARF1) is required for these processes in mammalian oocytes. Mutations of Marf1 cause female infertility characterized by up-regulation of a cohort of transcripts, increased retrotransposon expression, defective cytoplasmic maturation, and meiotic arrest. Up-regulation of protein phosphatase 2 catalytic subunit (PPP2CB) is key to the meiotic arrest phenotype. Moreover, Iap and Line1 retrotransposon messenger RNAs are also up-regulated, and, concomitantly, DNA double-strand breaks are elevated in mutant oocytes. Therefore MARF1, by suppressing levels of specific transcripts, is an essential regulator of important oogenic processes leading to female fertility and the development of healthy offspring.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612990/" 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/PMC3612990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, You-Qiang -- Sugiura, Koji -- Sun, Fengyun -- Pendola, Janice K -- Cox, Gregory A -- Handel, Mary Ann -- Schimenti, John C -- Eppig, John J -- CA34196/CA/NCI NIH HHS/ -- HD42137/HD/NICHD NIH HHS/ -- P01 HD042137/HD/NICHD NIH HHS/ -- P30 CA034196/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1496-9. doi: 10.1126/science.1214680.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Jackson Laboratory, Bar Harbor, ME 04609, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442484" target="_blank"〉PubMed〈/a〉

    Secreted kinase phosphorylates extracellular proteins that regulate biomineralization (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-15
    Description: Protein phosphorylation is a fundamental mechanism regulating nearly every aspect of cellular life. Several secreted proteins are phosphorylated, but the kinases responsible are unknown. We identified a family of atypical protein kinases that localize within the Golgi apparatus and are secreted. Fam20C appears to be the Golgi casein kinase that phosphorylates secretory pathway proteins within S-x-E motifs. Fam20C phosphorylates the caseins and several secreted proteins implicated in biomineralization, including the small integrin-binding ligand, N-linked glycoproteins (SIBLINGs). Consequently, mutations in Fam20C cause an osteosclerotic bone dysplasia in humans known as Raine syndrome. Fam20C is thus a protein kinase dedicated to the phosphorylation of extracellular proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754843/" 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/PMC3754843/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tagliabracci, Vincent S -- Engel, James L -- Wen, Jianzhong -- Wiley, Sandra E -- Worby, Carolyn A -- Kinch, Lisa N -- Xiao, Junyu -- Grishin, Nick V -- Dixon, Jack E -- DK018024-37/DK/NIDDK NIH HHS/ -- DK018849-36/DK/NIDDK NIH HHS/ -- GM094575/GM/NIGMS NIH HHS/ -- R01 DK018849/DK/NIDDK NIH HHS/ -- R37 DK018024/DK/NIDDK NIH HHS/ -- T32 CA009523/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1150-3. doi: 10.1126/science.1217817.

    Mutations in the neverland gene turned Drosophila pachea into an obligate specialist species (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-29
    Description: Most living species exploit a limited range of resources. However, little is known about how tight associations build up during evolution between such specialist species and the hosts they use. We examined the dependence of Drosophila pachea on its single host, the senita cactus. Several amino acid changes in the Neverland oxygenase rendered D. pachea unable to transform cholesterol into 7-dehydrocholesterol (the first reaction in the steroid hormone biosynthetic pathway in insects) and thus made D. pachea dependent on the uncommon sterols of its host plant. The neverland mutations increase survival on the cactus's unusual sterols and are in a genomic region that faced recent positive selection. This study illustrates how relatively few genetic changes in a single gene may restrict the ecological niche of a species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4729188/" 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/PMC4729188/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lang, Michael -- Murat, Sophie -- Clark, Andrew G -- Gouppil, Geraldine -- Blais, Catherine -- Matzkin, Luciano M -- Guittard, Emilie -- Yoshiyama-Yanagawa, Takuji -- Kataoka, Hiroshi -- Niwa, Ryusuke -- Lafont, Rene -- Dauphin-Villemant, Chantal -- Orgogozo, Virginie -- AI064950/AI/NIAID NIH HHS/ -- R01 AI064950/AI/NIAID NIH HHS/ -- R01 HG003229/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1658-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CNRS UMR7592, Universite Paris Diderot, Sorbonne Paris Cite, Institut Jacques Monod, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23019649" target="_blank"〉PubMed〈/a〉

    Identification and functional expression of the mitochondrial pyruvate carrier (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-26
    Description: The transport of pyruvate, the end product of glycolysis, into mitochondria is an essential process that provides the organelle with a major oxidative fuel. Although the existence of a specific mitochondrial pyruvate carrier (MPC) has been anticipated, its molecular identity remained unknown. We report that MPC is a heterocomplex formed by two members of a family of previously uncharacterized membrane proteins that are conserved from yeast to mammals. Members of the MPC family were found in the inner mitochondrial membrane, and yeast mutants lacking MPC proteins showed severe defects in mitochondrial pyruvate uptake. Coexpression of mouse MPC1 and MPC2 in Lactococcus lactis promoted transport of pyruvate across the membrane. These observations firmly establish these proteins as essential components of the MPC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herzig, Sebastien -- Raemy, Etienne -- Montessuit, Sylvie -- Veuthey, Jean-Luc -- Zamboni, Nicola -- Westermann, Benedikt -- Kunji, Edmund R S -- Martinou, Jean-Claude -- MC_U105663139/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Jul 6;337(6090):93-6. doi: 10.1126/science.1218530.

    Highly conserved protective epitopes on influenza B viruses (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-11
    Description: Identification of broadly neutralizing antibodies against influenza A viruses has raised hopes for the development of monoclonal antibody-based immunotherapy and "universal" vaccines for influenza. However, a substantial part of the annual flu burden is caused by two cocirculating, antigenically distinct lineages of influenza B viruses. Here, we report human monoclonal antibodies, CR8033, CR8071, and CR9114, that protect mice against lethal challenge from both lineages. Antibodies CR8033 and CR8071 recognize distinct conserved epitopes in the head region of the influenza B hemagglutinin (HA), whereas CR9114 binds a conserved epitope in the HA stem and protects against lethal challenge with influenza A and B viruses. These antibodies may inform on development of monoclonal antibody-based treatments and a universal flu vaccine for all influenza A and B viruses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3538841/" 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/PMC3538841/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dreyfus, Cyrille -- Laursen, Nick S -- Kwaks, Ted -- Zuijdgeest, David -- Khayat, Reza -- Ekiert, Damian C -- Lee, Jeong Hyun -- Metlagel, Zoltan -- Bujny, Miriam V -- Jongeneelen, Mandy -- van der Vlugt, Remko -- Lamrani, Mohammed -- Korse, Hans J W M -- Geelen, Eric -- Sahin, Ozcan -- Sieuwerts, Martijn -- Brakenhoff, Just P J -- Vogels, Ronald -- Li, Olive T W -- Poon, Leo L M -- Peiris, Malik -- Koudstaal, Wouter -- Ward, Andrew B -- Wilson, Ian A -- Goudsmit, Jaap -- Friesen, Robert H E -- GM080209/GM/NIGMS NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- RR017573/RR/NCRR NIH HHS/ -- T32 GM080209/GM/NIGMS NIH HHS/ -- U54 GM094586/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 14;337(6100):1343-8. doi: 10.1126/science.1222908.

    Identification of small molecule activators of cryptochrome (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-17
    Description: Impairment of the circadian clock has been associated with numerous disorders, including metabolic disease. Although small molecules that modulate clock function might offer therapeutic approaches to such diseases, only a few compounds have been identified that selectively target core clock proteins. From an unbiased cell-based circadian phenotypic screen, we identified KL001, a small molecule that specifically interacts with cryptochrome (CRY). KL001 prevented ubiquitin-dependent degradation of CRY, resulting in lengthening of the circadian period. In combination with mathematical modeling, our studies using KL001 revealed that CRY1 and CRY2 share a similar functional role in the period regulation. Furthermore, KL001-mediated CRY stabilization inhibited glucagon-induced gluconeogenesis in primary hepatocytes. KL001 thus provides a tool to study the regulation of CRY-dependent physiology and aid development of clock-based therapeutics of diabetes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3589997/" 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/PMC3589997/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirota, Tsuyoshi -- Lee, Jae Wook -- St John, Peter C -- Sawa, Mariko -- Iwaisako, Keiko -- Noguchi, Takako -- Pongsawakul, Pagkapol Y -- Sonntag, Tim -- Welsh, David K -- Brenner, David A -- Doyle, Francis J 3rd -- Schultz, Peter G -- Kay, Steve A -- GM074868/GM/NIGMS NIH HHS/ -- GM085764/GM/NIGMS NIH HHS/ -- GM096873/GM/NIGMS NIH HHS/ -- MH051573/MH/NIMH NIH HHS/ -- MH082945/MH/NIMH NIH HHS/ -- P50 GM085764/GM/NIGMS NIH HHS/ -- R01 GM041804/GM/NIGMS NIH HHS/ -- R01 GM074868/GM/NIGMS NIH HHS/ -- R01 GM096873/GM/NIGMS NIH HHS/ -- R01 MH051573/MH/NIMH NIH HHS/ -- R01 MH082945/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 31;337(6098):1094-7. doi: 10.1126/science.1223710.

    Structural insight into the ion-exchange mechanism of the sodium/calcium exchanger (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-11
    Description: Sodium/calcium (Na(+)/Ca(2+)) exchangers (NCX) are membrane transporters that play an essential role in maintaining the homeostasis of cytosolic Ca(2+) for cell signaling. We demonstrated the Na(+)/Ca(2+)-exchange function of an NCX from Methanococcus jannaschii (NCX_Mj) and report its 1.9 angstrom crystal structure in an outward-facing conformation. Containing 10 transmembrane helices, the two halves of NCX_Mj share a similar structure with opposite orientation. Four ion-binding sites cluster at the center of the protein: one specific for Ca(2+) and three that likely bind Na(+). Two passageways allow for Na(+) and Ca(2+) access to the central ion-binding sites from the extracellular side. Based on the symmetry of NCX_Mj and its ability to catalyze bidirectional ion-exchange reactions, we propose a structure model for the inward-facing NCX_Mj.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liao, Jun -- Li, Hua -- Zeng, Weizhong -- Sauer, David B -- Belmares, Ricardo -- Jiang, Youxing -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Feb 10;335(6069):686-90. doi: 10.1126/science.1215759.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, University of Texas Southwestern Medical Center, Dallas, TX 75390-9040, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22323814" target="_blank"〉PubMed〈/a〉

    Crystal structure of the heterodimeric CLOCK:BMAL1 transcriptional activator complex (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-02
    Description: The circadian clock in mammals is driven by an autoregulatory transcriptional feedback mechanism that takes approximately 24 hours to complete. A key component of this mechanism is a heterodimeric transcriptional activator consisting of two basic helix-loop-helix PER-ARNT-SIM (bHLH-PAS) domain protein subunits, CLOCK and BMAL1. Here, we report the crystal structure of a complex containing the mouse CLOCK:BMAL1 bHLH-PAS domains at 2.3 A resolution. The structure reveals an unusual asymmetric heterodimer with the three domains in each of the two subunits--bHLH, PAS-A, and PAS-B--tightly intertwined and involved in dimerization interactions, resulting in three distinct protein interfaces. Mutations that perturb the observed heterodimer interfaces affect the stability and activity of the CLOCK:BMAL1 complex as well as the periodicity of the circadian oscillator. The structure of the CLOCK:BMAL1 complex is a starting point for understanding at an atomic level the mechanism driving the mammalian circadian clock.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3694778/" 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/PMC3694778/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Nian -- Chelliah, Yogarany -- Shan, Yongli -- Taylor, Clinton A -- Yoo, Seung-Hee -- Partch, Carrie -- Green, Carla B -- Zhang, Hong -- Takahashi, Joseph S -- R01 GM081875/GM/NIGMS NIH HHS/ -- R01 GM090247/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):189-94. doi: 10.1126/science.1222804.

DOC2 proteins recruit the membrane fusion machinery required for exocytosis in a Ca(2+)-dependent fashion. Here, the phenotype of a Toxoplasma gondii conditional mutant impaired in host cell invasion and egress was pinpointed to a defect in secretion of the micronemes, an apicomplexan-specific organelle that contains adhesion proteins. Whole-genome sequencing identified the etiological point mutation in TgDOC2.1. A conditional allele of the orthologous gene engineered into Plasmodium falciparum was also defective in microneme secretion. However, the major effect was on invasion, suggesting that microneme secretion is dispensable for Plasmodium egress.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3354045/" 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/PMC3354045/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Farrell, Andrew -- Thirugnanam, Sivasakthivel -- Lorestani, Alexander -- Dvorin, Jeffrey D -- Eidell, Keith P -- Ferguson, David J P -- Anderson-White, Brooke R -- Duraisingh, Manoj T -- Marth, Gabor T -- Gubbels, Marc-Jan -- AI057919/AI/NIAID NIH HHS/ -- AI081220/AI/NIAID NIH HHS/ -- AI087874/AI/NIAID NIH HHS/ -- AI088314/AI/NIAID NIH HHS/ -- HG004719/HG/NHGRI NIH HHS/ -- K08 AI087874/AI/NIAID NIH HHS/ -- K08 AI087874-02/AI/NIAID NIH HHS/ -- R01 AI057919/AI/NIAID NIH HHS/ -- R01 HG004719/HG/NHGRI NIH HHS/ -- R21 AI081220/AI/NIAID NIH HHS/ -- R21 AI088314/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):218-21. doi: 10.1126/science.1210829.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Boston College, Chestnut Hill, MA 02467, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246776" target="_blank"〉PubMed〈/a〉

    Description: Influenza A virus (IAV) infection leads to variable and imperfectly understood pathogenicity. We report that segment 3 of the virus contains a second open reading frame ("X-ORF"), accessed via ribosomal frameshifting. The frameshift product, termed PA-X, comprises the endonuclease domain of the viral PA protein with a C-terminal domain encoded by the X-ORF and functions to repress cellular gene expression. PA-X also modulates IAV virulence in a mouse infection model, acting to decrease pathogenicity. Loss of PA-X expression leads to changes in the kinetics of the global host response, which notably includes increases in inflammatory, apoptotic, and T lymphocyte-signaling pathways. Thus, we have identified a previously unknown IAV protein that modulates the host response to infection, a finding with important implications for understanding IAV pathogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552242/" 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/PMC3552242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jagger, B W -- Wise, H M -- Kash, J C -- Walters, K-A -- Wills, N M -- Xiao, Y-L -- Dunfee, R L -- Schwartzman, L M -- Ozinsky, A -- Bell, G L -- Dalton, R M -- Lo, A -- Efstathiou, S -- Atkins, J F -- Firth, A E -- Taubenberger, J K -- Digard, P -- 073126/Wellcome Trust/United Kingdom -- 088789/Wellcome Trust/United Kingdom -- G0700815/Medical Research Council/United Kingdom -- G0700815(82260)/Medical Research Council/United Kingdom -- G9800943/Medical Research Council/United Kingdom -- MR/J002232/1/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):199-204. doi: 10.1126/science.1222213.
