    Description: Promoter-specific recruitment of histone acetyltransferase activity is often critical for transcriptional activation. We present a detailed study of the interaction between the histone acetyltransferase complexes SAGA and NuA4, and transcription activators. We demonstrate by affinity chromatography and photo-cross-linking label transfer that acidic activators directly interact with Tra1p, a shared subunit of SAGA and NuA4. Mutations within the COOH-terminus of Tra1p disrupted its interaction with activators and resulted in gene-specific transcriptional defects that correlated with lowered promoter-specific histone acetylation. These data demonstrate that the essential Tra1 protein serves as a common target for activators in both SAGA and NuA4 acetyltransferases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, C E -- Howe, L -- Sousa, K -- Alley, S C -- Carrozza, M J -- Tan, S -- Workman, J L -- GM19492/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Jun 22;292(5525):2333-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biochemistry and Molecular Biology, Department of Chemistry, The Pennsylvania State University, 306 Althouse Laboratory, University Park, PA 16802, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11423663" target="_blank"〉PubMed〈/a〉

    Description: The SWI/SNF complex participates in the restructuring of chromatin for transcription. The function of the yeast SWI/SNF complex in the remodeling of a nucleosome array has now been analyzed in vitro. Binding of the purified SWI/SNF complex to a nucleosome array disrupted multiple nucleosomes in an adenosine triphosphate-dependent reaction. However, removal of SWI/SNF left a deoxyribonuclease I-hypersensitive site specifically at a nucleosome that was bound by derivatives of the transcription factor Gal4p. Analysis of individual nucleosomes revealed that the SWI/SNF complex catalyzed eviction of histones from the Gal4-bound nucleosomes. Thus, the transient action of the SWI/SNF complex facilitated irreversible disruption of transcription factor-bound nucleosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owen-Hughes, T -- Utley, R T -- Cote, J -- Peterson, C L -- Workman, J L -- GM47867/GM/NIGMS NIH HHS/ -- R01 GM049650/GM/NIGMS NIH HHS/ -- R37 GM049650/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Jul 26;273(5274):513-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology and Center for Gene Regulation, Pennsylvania State University, University Park, PA 16802-4500, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662543" target="_blank"〉PubMed〈/a〉

    Description: One of the most notable features of the vertebrate body plan organization is its bilateral symmetry, evident at the level of vertebrae and skeletal muscles. Here we show that a mutation in Rere (also known as atrophin2) leads to the formation of asymmetrical somites in mouse embryos, similar to embryos deprived of retinoic acid. Furthermore, we also demonstrate that Rere controls retinoic acid signalling, which is required to maintain somite symmetry by interacting with Fgf8 in the left-right signalling pathway. Rere forms a complex with Nr2f2, p300 (also known as Ep300) and a retinoic acid receptor, which is recruited to the retinoic acid regulatory element of retinoic acid targets, such as the Rarb promoter. Furthermore, the knockdown of Nr2f2 and/or Rere decreases retinoic acid signalling, suggesting that this complex is required to promote transcriptional activation of retinoic acid targets. The asymmetrical expression of Nr2f2 in the presomitic mesoderm overlaps with the asymmetry of the retinoic acid signalling response, supporting its implication in the control of somitic symmetry. Misregulation of this mechanism could be involved in symmetry defects of the human spine, such as those observed in patients with scoliosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vilhais-Neto, Goncalo C -- Maruhashi, Mitsuji -- Smith, Karen T -- Vasseur-Cognet, Mireille -- Peterson, Andrew S -- Workman, Jerry L -- Pourquie, Olivier -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Feb 18;463(7283):953-7. doi: 10.1038/nature08763.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stowers Institute for Medical Research, Missouri 64110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20164929" target="_blank"〉PubMed〈/a〉

    Description: In order to function, transcription factors must compete for DNA binding with structural components of chromatin, including nucleosomes. Mechanisms that could be used in this competition have been characterized with the use of the DNA binding domain of the yeast GAL4 protein. The binding of GAL4 to a nucleosome core resulted in a ternary complex containing GAL4, the core histone proteins, and DNA. This ternary complex was unstable; upon the addition of nonspecific competitor DNA, it dissociated into either the original nucleosome core particle or GAL4 bound to naked DNA. Nucleosome core destabilization by GAL4 did not require a transcriptional activation domain. These data demonstrate the displacement of nucleosome cores as a direct result of binding by a regulatory factor. Similar mechanisms might affect the establishment of factor occupancy of promoters and enhancers in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Workman, J L -- Kingston, R E -- New York, N.Y. -- Science. 1992 Dec 11;258(5089):1780-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1465613" target="_blank"〉PubMed〈/a〉

    Description: The positioning of nucleosomes within the coding regions of eukaryotic genes is aligned with respect to transcriptional start sites. This organization is likely to influence many genetic processes, requiring access to the underlying DNA. Here, we show that the combined action of Isw1 and Chd1 nucleosome-spacing enzymes is required to maintain this organization. In the absence of these enzymes, regular positioning of the majority of nucleosomes is lost. Exceptions include the region upstream of the promoter, the +1 nucleosome, and a subset of locations distributed throughout coding regions where other factors are likely to be involved. These observations indicate that adenosine triphosphate-dependent remodeling enzymes are responsible for directing the positioning of the majority of nucleosomes within the Saccharomyces cerevisiae genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428865/" 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/PMC3428865/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gkikopoulos, Triantaffyllos -- Schofield, Pieta -- Singh, Vijender -- Pinskaya, Marina -- Mellor, Jane -- Smolle, Michaela -- Workman, Jerry L -- Barton, Geoffrey J -- Owen-Hughes, Tom -- 064414/Wellcome Trust/United Kingdom -- 095062/Wellcome Trust/United Kingdom -- G0900740/Medical Research Council/United Kingdom -- R01 GM047867/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Sep 23;333(6050):1758-60. doi: 10.1126/science.1206097.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Gene Regulation and Expression, College of Life Sciences, University of Dundee, Dundee, DD1 5EH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21940898" target="_blank"〉PubMed〈/a〉

    Description: Phosphorylation of the human histone variant H2A.X and H2Av, its homolog in Drosophila melanogaster, occurs rapidly at sites of DNA double-strand breaks. Little is known about the function of this phosphorylation or its removal during DNA repair. Here, we demonstrate that the Drosophila Tip60 (dTip60) chromatin-remodeling complex acetylates nucleosomal phospho-H2Av and exchanges it with an unmodified H2Av. Both the histone acetyltransferase dTip60 as well as the adenosine triphosphatase Domino/p400 catalyze the exchange of phospho-H2Av. Thus, these data reveal a previously unknown mechanism for selective histone exchange that uses the concerted action of two distinct chromatin-remodeling enzymes within the same multiprotein complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kusch, Thomas -- Florens, Laurence -- Macdonald, W Hayes -- Swanson, Selene K -- Glaser, Robert L -- Yates, John R 3rd -- Abmayr, Susan M -- Washburn, Michael P -- Workman, Jerry L -- New York, N.Y. -- Science. 2004 Dec 17;306(5704):2084-7.

    Description: Set2-mediated methylation of histone H3 at Lys 36 (H3K36me) is a co-transcriptional event that is necessary for the activation of the Rpd3S histone deacetylase complex, thereby maintaining the coding region of genes in a hypoacetylated state. In the absence of Set2, H3K36 or Rpd3S acetylated histones accumulate on open reading frames (ORFs), leading to transcription initiation from cryptic promoters within ORFs. Although the co-transcriptional deacetylation pathway is well characterized, the factors responsible for acetylation are as yet unknown. Here we show that, in yeast, co-transcriptional acetylation is achieved in part by histone exchange over ORFs. In addition to its function of targeting and activating the Rpd3S complex, H3K36 methylation suppresses the interaction of H3 with histone chaperones, histone exchange over coding regions and the incorporation of new acetylated histones. Thus, Set2 functions both to suppress the incorporation of acetylated histones and to signal for the deacetylation of these histones in transcribed genes. By suppressing spurious cryptic transcripts from initiating within ORFs, this pathway is essential to maintain the accuracy of transcription by RNA polymerase II.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Venkatesh, Swaminathan -- Smolle, Michaela -- Li, Hua -- Gogol, Madelaine M -- Saint, Malika -- Kumar, Shambhu -- Natarajan, Krishnamurthy -- Workman, Jerry L -- R01GM04867/GM/NIGMS NIH HHS/ -- England -- Nature. 2012 Sep 20;489(7416):452-5. doi: 10.1038/nature11326.

    Description: The SWI/SNF protein complex is required for the enhancement of transcription by many transcriptional activators in yeast. Here it is shown that the purified SWI/SNF complex is composed of 10 subunits and includes the SWI1, SWI2/SNF2, SWI3, SNF5, and SNF6 gene products. The complex exhibited DNA-stimulated adenosine triphosphatase (ATPase) activity, but lacked helicase activity. The SWI/SNF complex caused a 10- to 30-fold stimulation in the binding of GAL4 derivatives to nucleosomal DNA in a reaction that required adenosine triphosphate (ATP) hydrolysis but was activation domain-independent. Stimulation of GAL4 binding by the complex was abolished by a mutant SWI2 subunit, and was increased by the presence of a histone-binding protein, nucleoplasmin. A direct ATP-dependent interaction between the SWI/SNF complex and nucleosomal DNA was detected. These observations suggest that a primary role of the SWI/SNF complex is to promote activator binding to nucleosomal DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cote, J -- Quinn, J -- Workman, J L -- Peterson, C L -- GM47867-02/GM/NIGMS NIH HHS/ -- GM49650-01/GM/NIGMS NIH HHS/ -- R01 GM049650/GM/NIGMS NIH HHS/ -- R37 GM049650/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 1;265(5168):53-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Pennsylvania State University, University Park 16802.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8016655" target="_blank"〉PubMed〈/a〉
