    Cloning of the 62-kilodalton component of basic transcription factor BTF2 (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1992-09-04
    Beschreibung: Cloning of the mammalian basic transcription factors serves as a major step in understanding the mechanism of transcription initiation. The 62-kilodalton component (p62) of one of these transcription factors, BTF2 was cloned and overexpressed. A monoclonal antibody to this polypeptide inhibited transcription in vitro. Immunoaffinity experiments demonstrated that the 62-kilodalton component is closely associated with the other polypeptides present in the BTF2 factor. Sequence similarity suggests that BTF2 may be the human counterpart of RNA polymerase II initiation factor b from yeast.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fischer, L -- Gerard, M -- Chalut, C -- Lutz, Y -- Humbert, S -- Kanno, M -- Chambon, P -- Egly, J M -- New York, N.Y. -- Science. 1992 Sep 4;257(5075):1392-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes, Centre National de la Recherche Scientifique, Unite 184, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1529339" target="_blank"〉PubMed〈/a〉

    Retinoic acid signaling affects cortical synchrony during sleep (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-10-08
    Beschreibung: Delta oscillations, characteristic of the electroencephalogram (EEG) of slow wave sleep, estimate sleep depth and need and are thought to be closely linked to the recovery function of sleep. The cellular mechanisms underlying the generation of delta waves at the cortical and thalamic levels are well documented, but the molecular regulatory mechanisms remain elusive. Here we demonstrate in the mouse that the gene encoding the retinoic acid receptor beta determines the contribution of delta oscillations to the sleep EEG. Thus, retinoic acid signaling, which is involved in the patterning of the brain and dopaminergic pathways, regulates cortical synchrony in the adult.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maret, Stephanie -- Franken, Paul -- Dauvilliers, Yves -- Ghyselinck, Norbert B -- Chambon, Pierre -- Tafti, Mehdi -- New York, N.Y. -- Science. 2005 Oct 7;310(5745):111-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Integrative Genomics, University of Lausanne, Genopode, 1015 Lausanne-Dorigny, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16210540" target="_blank"〉PubMed〈/a〉

    DNA repair helicase: a component of BTF2 (TFIIH) basic transcription factor (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1993-04-02
    Beschreibung: The human BTF2 basic transcription factor (also called TFIIH), which is similar to the delta factor in rat and factor b in yeast, is required for class II gene transcription. A strand displacement assay was used to show that highly purified preparation of BTF2 had an adenosine triphosphate-dependent DNA helicase activity, in addition to the previously characterized carboxyl-terminal domain kinase activity. Amino acid sequence analysis of the tryptic digest generated from the 89-kilodalton subunit of BTF2 indicated that this polypeptide corresponded to the ERCC-3 gene product, a presumed helicase implicated in the human DNA excision repair disorders xeroderma pigmentosum and Cockayne's syndrome. These findings suggest that transcription and nucleotide excision repair may share common factors and hence may be considered to be functionally related.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schaeffer, L -- Roy, R -- Humbert, S -- Moncollin, V -- Vermeulen, W -- Hoeijmakers, J H -- Chambon, P -- Egly, J M -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):58-63.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UPR 6520 (CNRS), Unite 184 (INSERM), Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8465201" target="_blank"〉PubMed〈/a〉

    Repression of the immunoglobulin heavy chain enhancer by the adenovirus-2 E1A products (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1985-12-20
    Beschreibung: The products of the adenovirus-2 (Ad2) immortalizing oncogene E1A repress the activity of the SV40, polyoma virus and E1A enhancers. Evidence is presented that Ad2 infection of MPC11 plasmocytoma cells results in an inhibition of transcription of both the gamma 2b heavy chain (IgH) and the kappa light chain immunoglobulin genes. This inhibition is caused by the Ad2 E1A products. Furthermore, the Ad2 E1A products repress transcription activated by the immunoglobulin heavy chain enhancer in chimeric recombinants, which are either stably integrated in the genome of lymphoid cells or are present as episomes. The implications of negative regulation of cellular enhancers are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hen, R -- Borrelli, E -- Chambon, P -- New York, N.Y. -- Science. 1985 Dec 20;230(4732):1391-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2999984" target="_blank"〉PubMed〈/a〉
