SPT15 (P13393) - Overview - Molecular Target Synopsis


SPT15, TATA-box-binding protein
UniProt P13393

Also Known as TBP_YEAST, SPT15, BTF1, TBP1

General transcription factor that functions at the core 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 preinitiation 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. Binds DNA as monomer. The 1.2 MDa TFIID complex is composed of TATA binding protein (TBP) and the 14 TBP-associated factors. One copy of each TAF1, TAF2, TAF3, TAF7, TAF8, TAF11, TAF13, two copies of each TAF4, TAF5, TAF6, TAF9, TAF10, TAF12, and three copies of TAF14. Interacts with TFC8.
