  • Relevance

    TAF1 functions as a component of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in pre-initiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and selectivity, TFIIA and TFIIB interaction, chromatin modification (histone acetylation by TAF1), facilitation of DNA opening and initiation of transcription. Compared to higher eukaryotes TAF1, yeast TAF1 lacks the C-terminal bromodomains and C-terminal kinase activity. The TFIID interacting proteins BDF1 and BDF2 may substitute for these domains.
