    A transcriptional enhancer 3' of C beta 2 in the T cell receptor beta locus (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-08
    Description: Run-on transcription experiments were used to demonstrate that transcription of T cell receptor beta chain V genes is activated by DNA rearrangement, in a manner similar to immunoglobulin genes. A transcriptional enhancer likely to be involved in this activation has been identified. A 25-kilobase region from J beta 1 to V beta 14 was tested for enhancer activity by transient transfections, and an enhancer was found 7.5 kilobases 3' of C beta 2. The beta enhancer has low activity relative to the simian virus 40 viral enhancer, does not display a preference for V beta promoters, has a T cell-specific activity, and binds two purified immunoglobulin heavy chain enhancer factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDougall, S -- Peterson, C L -- Calame, K -- GM29361/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 8;241(4862):205-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, UCLA School of Medicine 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2968651" target="_blank"〉PubMed〈/a〉

    Roles of SWI1, SWI2, and SWI3 proteins for transcriptional enhancement by steroid receptors (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-12-04
    Description: The SWI1, SWI2, and SWI3 proteins, which are required for regulated transcription of numerous yeast genes, were found also to be essential for rat glucocorticoid receptor function in yeast; the receptor failed to activate transcription in strains with mutations in the SWI1, SWI2, or SWI3 genes. Certain mutations in genes encoding components of chromatin, identified as suppressors of swi mutations, partially relieved the SWI- requirement for receptor function. Immunoprecipitation of glucocorticoid receptor derivatives from wild-type (SWI+) yeast extracts coprecipitated the SWI3 protein; such receptor-SWI3 complexes were not detected in swi1- or swi2- mutant strains, implying that a complex of multiple SWI proteins may associate with the receptor. Prior incubation of a Drosophila embryo transcription extract with the yeast SWI3-specific antibody inhibited receptor function in vitro whereas the antibody had no effect if added after initiation complex formation. Thus, positive regulation by the glucocorticoid receptor in vivo and in vitro appears to require its interaction, at an early step, with one or more SWI proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshinaga, S K -- Peterson, C L -- Herskowitz, I -- Yamamoto, K R -- New York, N.Y. -- Science. 1992 Dec 4;258(5088):1598-604.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco 94143-0448.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1360703" target="_blank"〉PubMed〈/a〉

    Stimulation of GAL4 derivative binding to nucleosomal DNA by the yeast SWI/SNF complex (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-01
    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〉
