Description:
CREB binding protein (CBP) functions as an essential coactivator of transcription factors that are inhibited by the adenovirus early gene product E1A. Transcriptional activation by the signal transducer and activator of transcription-1 (STAT1) protein requires the C/H3 domain in CBP, which is the primary target of E1A inhibition. Here it was found that the C/H3 domain is not required for retinoic acid receptor (RAR) function, nor is it involved in E1A inhibition. Instead, E1A inhibits RAR function by preventing the assembly of CBP-nuclear receptor coactivator complexes, revealing differences in required CBP domains for transcriptional activation by RAR and STAT1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurokawa, R -- Kalafus, D -- Ogliastro, M H -- Kioussi, C -- Xu, L -- Torchia, J -- Rosenfeld, M G -- Glass, C K -- New York, N.Y. -- Science. 1998 Jan 30;279(5351):700-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cellular and Molecular Medicine, Department of Medicine, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0651, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9445474" target="_blank"〉PubMed〈/a〉
