Description
TFIID is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors.
TAFs are components of the transcription factor IID (TFIID) complex, PCAF histone acetylase complex and TBP-free TAFII complex (TFTC). TIIFD is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. May regulate cyclin E expression.
Subunit
TFIID and PCAF are composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). TBP is not part of TFTC. Component of the PCAF complex, at least composed of TADA2L/ADA2, TADA3L/ADA3, SUPT3H, TAF5L, TAF6L, TAF9, TAF10, TAF12 and TRRAP. Component of the TFTC-HAT complex, at least composed of TAF5L, TAF6L, TADA3L, SUPT3H, TAF2, TAF4, TAF5, GCN5L2/GCN5, TAF10 and TRRAP. Component of the STAGA transcription coactivator-HAT complex, at least composed of SUPT3H, GCN5L2, TAF5L, TAF6L, SUPT7L, TADA3L, TAD1L, TAF10, TAF12, TRRAP and TAF9. The STAGA core complex is associated with a subcomplex required for histone deubiquitination composed of ATXN7L3, ENY2 and USP22 (By similarity). Interacts with TAF3 (PubMed:11438666). Interacts with LOXL2 (By similarity).
