Shidlovskii1,3 A Novel Conserved Domain of SAYP Coactivator Mediates the Interaction of TFIID and Brahma Transcription Complexes 1Institute of Gene Biology, Russian Academy of Sciences, Moscow, 119334 Russia2Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, Moscow, 119991 Russia 3Centre for Medical Studies at Moscow, Moscow, 119334 Russia *nvorobyova@gmail.com Received - 2009-12-25; Accepted - 2010-03-10 Using the S2 cell system of Drosophila melanogaster, it was shown that the key protein domain mediating the interaction of TFIID and Brahma transcriptional complexes within the BTFly supercomplex is the evolutionary conserved SAY domain of SAYP. TFIID and Brahma coactivators participated in the reporter gene activation induced by the SAY domain in cellular nuclei. The components of TFIID and Brahma directly interacting with SAY were identified. transcriptional factor, activation of transcription, promoter, chromatin remodeling complex, coprecipitation, eukaryotes |
