    Mass spectrometric analysis of the anaphase-promoting complex from yeast: identification of a subunit related to cullins (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-03-21
    Description: Entry into anaphase and exit from mitosis depend on a ubiquitin-protein ligase complex called the anaphase-promoting complex (APC) or cyclosome. At least 12 different subunits were detected in the purified particle from budding yeast, including the previously identified proteins Apc1p, Cdc16p, Cdc23p, Cdc26p, and Cdc27p. Five additional subunits purified in low nanogram amounts were identified by tandem mass spectrometric sequencing. Apc2p, Apc5p, and the RING-finger protein Apc11p are conserved from yeast to humans. Apc2p is similar to the cullin Cdc53p, which is a subunit of the ubiquitin-protein ligase complex SCFCdc4 required for the initiation of DNA replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zachariae, W -- Shevchenko, A -- Andrews, P D -- Ciosk, R -- Galova, M -- Stark, M J -- Mann, M -- Nasmyth, K -- New York, N.Y. -- Science. 1998 Feb 20;279(5354):1216-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute of Molecular Pathology, Dr. Bohr-Gasse 7, A-1030 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9469814" target="_blank"〉PubMed〈/a〉

    Structure of the anaphase-promoting complex/cyclosome interacting with a mitotic checkpoint complex (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-03-17
    Description: Once all chromosomes are connected to the mitotic spindle (bioriented), anaphase is initiated by the protein ubiquitylation activity of the anaphase-promoting complex/cyclosome (APC/C) and its coactivator Cdc20 (APC/C(Cdc20)). Before chromosome biorientation, anaphase is delayed by a mitotic checkpoint complex (MCC) that inhibits APC/C(Cdc20). We used single-particle electron microscopy to obtain three-dimensional models of human APC/C in various functional states: bound to MCC, to Cdc20, or to neither (apo-APC/C). These experiments revealed that MCC associates with the Cdc20 binding site on APC/C, locks the otherwise flexible APC/C in a "closed" state, and prevents binding and ubiquitylation of a wide range of different APC/C substrates. These observations clarify the structural basis for the inhibition of APC/C by spindle checkpoint proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2989460/" 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/PMC2989460/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herzog, Franz -- Primorac, Ivana -- Dube, Prakash -- Lenart, Peter -- Sander, Bjorn -- Mechtler, Karl -- Stark, Holger -- Peters, Jan-Michael -- F 3407/Austrian Science Fund FWF/Austria -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1477-81. doi: 10.1126/science.1163300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute of Molecular Pathology, Dr. Bohr-Gasse 7, 1030 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286556" target="_blank"〉PubMed〈/a〉

    Systematic analysis of human protein complexes identifies chromosome segregation proteins (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-03
    Description: Chromosome segregation and cell division are essential, highly ordered processes that depend on numerous protein complexes. Results from recent RNA interference screens indicate that the identity and composition of these protein complexes is incompletely understood. Using gene tagging on bacterial artificial chromosomes, protein localization, and tandem-affinity purification-mass spectrometry, the MitoCheck consortium has analyzed about 100 human protein complexes, many of which had not or had only incompletely been characterized. This work has led to the discovery of previously unknown, evolutionarily conserved subunits of the anaphase-promoting complex and the gamma-tubulin ring complex--large complexes that are essential for spindle assembly and chromosome segregation. The approaches we describe here are generally applicable to high-throughput follow-up analyses of phenotypic screens in mammalian cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2989461/" 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/PMC2989461/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hutchins, James R A -- Toyoda, Yusuke -- Hegemann, Bjorn -- Poser, Ina -- Heriche, Jean-Karim -- Sykora, Martina M -- Augsburg, Martina -- Hudecz, Otto -- Buschhorn, Bettina A -- Bulkescher, Jutta -- Conrad, Christian -- Comartin, David -- Schleiffer, Alexander -- Sarov, Mihail -- Pozniakovsky, Andrei -- Slabicki, Mikolaj Michal -- Schloissnig, Siegfried -- Steinmacher, Ines -- Leuschner, Marit -- Ssykor, Andrea -- Lawo, Steffen -- Pelletier, Laurence -- Stark, Holger -- Nasmyth, Kim -- Ellenberg, Jan -- Durbin, Richard -- Buchholz, Frank -- Mechtler, Karl -- Hyman, Anthony A -- Peters, Jan-Michael -- F 3407/Austrian Science Fund FWF/Austria -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):593-9. doi: 10.1126/science.1181348.

    Defective TNF-alpha-induced apoptosis in STAT1-null cells due to low constitutive levels of caspases (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: Signal transducers and activators of transcription (STATs) enhance transcription of specific genes in response to cytokines and growth factors. STAT1 is also required for efficient constitutive expression of the caspases Ice, Cpp32, and Ich-1 in human fibroblasts. As a consequence, STAT1-null cells are resistant to apoptosis by tumor necrosis factor alpha (TNF-alpha). Reintroduction of STAT1alpha restored both TNF-alpha-induced apoptosis and the expression of Ice, Cpp32, and Ich-1. Variant STAT1 proteins carrying point mutations that inactivate domains required for STAT dimer formation nevertheless restored protease expression and sensitivity to apoptosis, indicating that the functions of STAT1 required for these activities are different from those that mediate induced gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kumar, A -- Commane, M -- Flickinger, T W -- Horvath, C M -- Stark, G R -- P01 CA62220/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1630-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Lerner Research Institute, The Cleveland Clinic Foundation, Cleveland, OH 44195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374464" target="_blank"〉PubMed〈/a〉

    Molecular architecture of the multiprotein splicing factor SF3b (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-10
    Description: The splicing factor SF3b is a multiprotein complex essential for the accurate excision of introns from pre-messenger RNA. As an integral component of the U2 small nuclear ribonucleoprotein (snRNP) and the U11/U12 di-snRNP, SF3b is involved in the recognition of the pre-messenger RNA's branch site within the major and minor spliceosomes. We have determined the three-dimensional structure of the human SF3b complex by single-particle electron cryomicroscopy at a resolution of less than 10 angstroms, allowing identification of protein domains with known structural folds. The best fit of a modeled RNA-recognition motif indicates that the protein p14 is located in the central cavity of the complex. The 22 tandem helical repeats of the protein SF3b155 are located in the outer shell of the complex enclosing p14.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Golas, Monika M -- Sander, Bjoern -- Will, Cindy L -- Luhrmann, Reinhard -- Stark, Holger -- New York, N.Y. -- Science. 2003 May 9;300(5621):980-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Biophysical Chemistry, Am Fassberg 11, 37077 Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12738865" target="_blank"〉PubMed〈/a〉

    Jak-STAT pathways and transcriptional activation in response to IFNs and other extracellular signaling proteins (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-03
    Description: Through the study of transcriptional activation in response to interferon alpha (IFN-alpha) and interferon gamma (IFN-gamma), a previously unrecognized direct signal transduction pathway to the nucleus has been uncovered: IFN-receptor interaction at the cell surface leads to the activation of kinases of the Jak family that then phosphorylate substrate proteins called STATs (signal transducers and activators of transcription). The phosphorylated STAT proteins move to the nucleus, bind specific DNA elements, and direct transcription. Recognition of the molecules involved in the IFN-alpha and IFN-gamma pathway has led to discoveries that a number of STAT family members exist and that other polypeptide ligands also use the Jak-STAT molecules in signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Darnell, J E Jr -- Kerr, I M -- Stark, G R -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1415-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Cell Biology, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8197455" target="_blank"〉PubMed〈/a〉

    A single phosphotyrosine residue of Stat91 required for gene activation by interferon-gamma (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-24
    Description: Interferon-gamma (IFN-gamma) stimulates transcription of specific genes by inducing tyrosine phosphorylation of a 91-kilodalton cytoplasmic protein (termed STAT for signal transducer and activator of transcription). Stat91 was phosphorylated on a single site (Tyr701), and phosphorylation of this site was required for nuclear translocation, DNA binding, and gene activation. Stat84, a differentially spliced product of the same gene that lacks the 38 carboxyl-terminal amino acids of Stat91, did not activate transcription, although it was phosphorylated and translocated to the nucleus and bound DNA. Thus, Stat91 mediates activation of transcription in response to IFN-gamma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shuai, K -- Stark, G R -- Kerr, I M -- Darnell, J E Jr -- AI32489-02/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 24;261(5129):1744-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rockefeller University, Laboratory of Molecular Cell Biology, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7690989" target="_blank"〉PubMed〈/a〉

    Pattern separation in the human hippocampal CA3 and dentate gyrus (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-22
    Description: Pattern separation, the process of transforming similar representations or memories into highly dissimilar, nonoverlapping representations, is a key component of many functions ascribed to the hippocampus. Computational models have stressed the role of the hippocampus and, in particular, the dentate gyrus and its projections into the CA3 subregion in pattern separation. We used high-resolution (1.5-millimeter isotropic voxels) functional magnetic resonance imaging to measure brain activity during incidental memory encoding. Although activity consistent with a bias toward pattern completion was observed in CA1, the subiculum, and the entorhinal and parahippocampal cortices, activity consistent with a strong bias toward pattern separation was observed in, and limited to, the CA3/dentate gyrus. These results provide compelling evidence of a key role of the human CA3/dentate gyrus in pattern separation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2829853/" 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/PMC2829853/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bakker, Arnold -- Kirwan, C Brock -- Miller, Michael -- Stark, Craig E L -- P41 RR15241-01A1/RR/NCRR NIH HHS/ -- R01 EB000975/EB/NIBIB NIH HHS/ -- R01 EB000975-04/EB/NIBIB NIH HHS/ -- R01 EB008171/EB/NIBIB NIH HHS/ -- R01 EB008171-01A1/EB/NIBIB NIH HHS/ -- R01 EB00975-01/EB/NIBIB NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1640-2. doi: 10.1126/science.1152882.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychological and Brain Sciences, Johns Hopkins University, Baltimore, MD, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18356518" target="_blank"〉PubMed〈/a〉

    Genome-wide quantitative enhancer activity maps identified by STARR-seq (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-01-19
    Description: Genomic enhancers are important regulators of gene expression, but their identification is a challenge, and methods depend on indirect measures of activity. We developed a method termed STARR-seq to directly and quantitatively assess enhancer activity for millions of candidates from arbitrary sources of DNA, which enables screens across entire genomes. When applied to the Drosophila genome, STARR-seq identifies thousands of cell type-specific enhancers across a broad continuum of strengths, links differential gene expression to differences in enhancer activity, and creates a genome-wide quantitative enhancer map. This map reveals the highly complex regulation of transcription, with several independent enhancers for both developmental regulators and ubiquitously expressed genes. STARR-seq can be used to identify and quantify enhancer activity in other eukaryotes, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arnold, Cosmas D -- Gerlach, Daniel -- Stelzer, Christoph -- Boryn, Lukasz M -- Rath, Martina -- Stark, Alexander -- New York, N.Y. -- Science. 2013 Mar 1;339(6123):1074-7. doi: 10.1126/science.1232542.
