    Requirement of tissue-selective TBP-associated factor TAFII105 in ovarian development (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-09-15
    Description: Transcription factor TFIID, composed of TBP and TAFII subunits, is a central component of the RNA polymerase II machinery. Here, we report that the tissue-selective TAFII105 subunit of TFIID is essential for proper development and function of the mouse ovary. Female mice lacking TAFII105 are viable but infertile because of a defect in folliculogenesis correlating with restricted expression of TAFII105 in the granulosa cells of the ovarian follicle. Gene expression profiling has uncovered a defective inhibin-activin signaling pathway in TAFII105-deficient ovaries. Together, these studies suggest that TAFII105 mediates the transcription of a subset of genes required for proper folliculogenesis in the ovary and establishes TAFII105 as a cell type-specific component of the mammalian transcriptional machinery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freiman, R N -- Albright, S R -- Zheng, S -- Sha, W C -- Hammer, R E -- Tjian, R -- New York, N.Y. -- Science. 2001 Sep 14;293(5537):2084-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, Howard Hughes Medical Institute, University of California at Berkeley, Berkeley, CA 94720-3204, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11557891" target="_blank"〉PubMed〈/a〉

    Structure and function of a human TAFII250 double bromodomain module (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-29
    Description: TFIID is a large multiprotein complex that initiates assembly of the transcription machinery. It is unclear how TFIID recognizes promoters in vivo when templates are nucleosome-bound. Here, it is shown that TAFII250, the largest subunit of TFIID, contains two tandem bromodomain modules that bind selectively to multiply acetylated histone H4 peptides. The 2.1 angstrom crystal structure of the double bromodomain reveals two side-by-side, four-helix bundles with a highly polarized surface charge distribution. Each bundle contains an Nepsilon-acetyllysine binding pocket at its center, which results in a structure ideally suited for recognition of diacetylated histone H4 tails. Thus, TFIID may be targeted to specific chromatin-bound promoters and may play a role in chromatin recognition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobson, R H -- Ladurner, A G -- King, D S -- Tjian, R -- New York, N.Y. -- Science. 2000 May 26;288(5470):1422-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Molecular and Cell Biology, 401 Barker Hall, University of California, Berkeley, CA 94720-3204, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10827952" target="_blank"〉PubMed〈/a〉

    Three-dimensional structure of the human TFIID-IIA-IIB complex (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-12-11
    Description: The multisubunit transcription factor IID (TFIID) is an essential component of the eukaryotic RNA polymerase II machinery that works in concert with TFIIA (IIA) and TFIIB (IIB) to assemble initiation complexes at core eukaryotic promoters. Here the structures of human TFIID and the TFIID-IIA-IIB complex that were obtained by electron microscopy and image analysis to 35 angstrom resolution are presented. TFIID is a trilobed, horseshoe-shaped structure, with TFIIA and TFIIB bound on opposite lobes and flanking a central cavity. Antibody studies locate the TATA-binding protein (TBP) between TFIIA and TFIIB at the top of the cavity that most likely encompasses the TATA DNA binding region of the supramolecular complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andel, F 3rd -- Ladurner, A G -- Inouye, C -- Tjian, R -- Nogales, E -- New York, N.Y. -- Science. 1999 Dec 10;286(5447):2153-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Life Science Division, Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10591646" target="_blank"〉PubMed〈/a〉

    Promoter-selective properties of the TBP-related factor TRF1 (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-08
    Description: The TATA-binding protein (TBP)-related factor 1 (TRF1) is expressed in a tissue-restricted fashion during Drosophila embryogenesis and may serve as a promoter-specific recognition factor that can replace TBP in regulating transcription. However, bona fide target promoters that would preferentially respond to TRF1 have remained elusive. Polytene chromosome staining, chromatin immunoprecipitation, direct messenger RNA analysis, and transient cotransfection assays identified the Drosophila gene tudor as containing a TRF1-responsive promoter. Reconstituted in vitro transcription reactions and deoxyribonuclease I footprinting assays confirmed the ability of TRF1 to bind preferentially and direct transcription of the tudor gene from an alternate promoter. Thus, metazoans appear to have evolved gene-selective and tissue-specific components of the core transcription machinery to regulate gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holmes, M C -- Tjian, R -- CA25417/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2000 May 5;288(5467):867-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10797011" target="_blank"〉PubMed〈/a〉

    Structure, function, and activator-induced conformations of the CRSP coactivator (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-02-09
    Description: The human cofactor complexes ARC (activator-recruited cofactor) and CRSP (cofactor required for Sp1 activation) mediate activator-dependent transcription in vitro. Although these complexes share several common subunits, their structural and functional relationships remain unknown. Here, we report that affinity-purified ARC consists of two distinct multisubunit complexes: a larger complex, denoted ARC-L, and a smaller coactivator, CRSP. Reconstituted in vitro transcription with biochemically separated ARC-L and CRSP reveals differential cofactor functions. The ARC-L complex is transcriptionally inactive, whereas the CRSP complex is highly active. Structural determination by electron microscopy (EM) and three-dimensional reconstruction indicate substantial differences in size and shape between ARC-L and CRSP. Moreover, EM analysis of independently derived CRSP complexes reveals distinct conformations induced by different activators. These results suggest that CRSP may potentiate transcription via specific activator-induced conformational changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taatjes, Dylan J -- Naar, Anders M -- Andel, Frank 3rd -- Nogales, Eva -- Tjian, Robert -- New York, N.Y. -- Science. 2002 Feb 8;295(5557):1058-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and, Lawrence Berkeley National Laboratory, Department of Molecular and Cell Biology, 401 Barker Hall, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11834832" target="_blank"〉PubMed〈/a〉

    The genome of the choanoflagellate Monosiga brevicollis and the origin of metazoans (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-02-15
    Description: Choanoflagellates are the closest known relatives of metazoans. To discover potential molecular mechanisms underlying the evolution of metazoan multicellularity, we sequenced and analysed the genome of the unicellular choanoflagellate Monosiga brevicollis. The genome contains approximately 9,200 intron-rich genes, including a number that encode cell adhesion and signalling protein domains that are otherwise restricted to metazoans. Here we show that the physical linkages among protein domains often differ between M. brevicollis and metazoans, suggesting that abundant domain shuffling followed the separation of the choanoflagellate and metazoan lineages. The completion of the M. brevicollis genome allows us to reconstruct with increasing resolution the genomic changes that accompanied the origin of metazoans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2562698/" 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/PMC2562698/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, Nicole -- Westbrook, M Jody -- Young, Susan L -- Kuo, Alan -- Abedin, Monika -- Chapman, Jarrod -- Fairclough, Stephen -- Hellsten, Uffe -- Isogai, Yoh -- Letunic, Ivica -- Marr, Michael -- Pincus, David -- Putnam, Nicholas -- Rokas, Antonis -- Wright, Kevin J -- Zuzow, Richard -- Dirks, William -- Good, Matthew -- Goodstein, David -- Lemons, Derek -- Li, Wanqing -- Lyons, Jessica B -- Morris, Andrea -- Nichols, Scott -- Richter, Daniel J -- Salamov, Asaf -- Sequencing, J G I -- Bork, Peer -- Lim, Wendell A -- Manning, Gerard -- Miller, W Todd -- McGinnis, William -- Shapiro, Harris -- Tjian, Robert -- Grigoriev, Igor V -- Rokhsar, Daniel -- R01 CA058530/CA/NCI NIH HHS/ -- R01 CA058530-14/CA/NCI NIH HHS/ -- R01 GM077197/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-01/HG/NHGRI NIH HHS/ -- R37 HD028315/HD/NICHD NIH HHS/ -- England -- Nature. 2008 Feb 14;451(7180):783-8. doi: 10.1038/nature06617.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology and the Center for Integrative Genomics, University of California, Berkeley, California 94720, USA. nking@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18273011" target="_blank"〉PubMed〈/a〉

    Leucine repeats and an adjacent DNA binding domain mediate the formation of functional cFos-cJun heterodimers (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-31
    Description: The discovery that the AP-1 family of enhancer binding factors includes a complex of the cellular Fos (cFos) and cellular Jun (cJun) proteins established a direct and important link between oncogenesis and transcriptional regulation. Homodimeric cJun protein synthesized in vitro is capable of binding selectively to AP-1 recognition sites, whereas the cFos polypeptide is not. When cotranslated, the cFos and cJun proteins can form a stable, heterodimeric complex with the DNA binding properties of AP-1/cJun. The related proteins Jun B and vJun are also able to form DNA binding complexes with cFos. Directed mutagenesis of the cFos protein reveals that a leucine repeat structure is required for binding to cJun, in a manner consistent with the proposed function of the "leucine zipper." A novel domain adjacent to, but distinct from, the leucine repeat of cFos is required for DNA binding by cFos-cJun heterodimers. Thus experimental evidence is presented that leucine repeats can mediate complex formation between heterologous proteins and that promotes further understanding of the molecular mechanisms underlying the function of two proto-oncogene products.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turner, R -- Tjian, R -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1689-94.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biochemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2494701" target="_blank"〉PubMed〈/a〉

    Functional domains and upstream activation properties of cloned human TATA binding protein (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-06-29
    Description: The TATA binding protein, TFIID, plays a central role in the initiation of eukaryotic mRNA synthesis. Here, we present a human cDNA clone for this factor. Comparison of its predicted protein sequence with those from Drosophila and yeast reveals a highly conserved carboxyl-terminal 180 amino acids. By contrast, the amino-terminal region of TFIID has diverged in both sequence and length. A striking feature of the human protein is a stretch of 38 glutamine residues in the NH2-terminal region. Expression of human TFIID in both Escherichia coli and HeLa cells produces a protein that binds specifically to a TATA box and promotes basal transcription; the conserved COOH-terminal portion of the protein is sufficient for both of these activities. Recombinant TFIID forms a stable complex on a TATA box either alone or in combination with either of the general transcription factors, TFIIA or TFIIB. Full-length recombinant TFIID is able to support Sp1 activated transcription in a TFIID-depleted nuclear extract, while a deletion of the NH2-terminal half of the protein is not. These results indicate the importance of the NH2-terminal region for upstream activation functions and suggest that additional factors (co-activators) are required for mediating interactions with specific regulators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peterson, M G -- Tanese, N -- Pugh, B F -- Tjian, R -- New York, N.Y. -- Science. 1990 Jun 29;248(4963):1625-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2363050" target="_blank"〉PubMed〈/a〉
