    Cloning of the 62-kilodalton component of basic transcription factor BTF2 (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-09-04
    Description: 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〉

    DNA repair helicase: a component of BTF2 (TFIIH) basic transcription factor (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-02
    Description: 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〉
