Research Backgrounds
Functions as a component of the DNA-binding general transcription factor complex TFIID, a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. Present in both of the previously described TFIID species which either lack or contain TAFII30 (TFIID alpha and TFIID beta respectively).
Phosphorylated by CIITA. Phosphorylation at Ser-264 by TAF1 in early G1 phase disrupts binding to TAF1.
Nucleus.
Ubiquitous.
TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). Part of a TFIID-containing RNA polymerase II pre-initiation complex that is composed of TBP and at least GTF2A1, GTF2A2, GTF2E1, GTF2E2, GTF2F1, GTF2H2, GTF2H3, GTF2H4, GTF2H5, GTF2B, TCEA1, ERCC2, ERCC3, TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13. Interacts with TAF1; the interaction is direct. Interacts with TAFII250, TAFII100, TAFII28, TAFII20, and TAFII18, but not with TAFII30 or TBP. Component of some MLL1/MLL complex, at least composed of the core components KMT2A/MLL1, ASH2L, HCFC1/HCF1, WDR5 and RBBP5, as well as the facultative components BAP18, CHD8, E2F6, HSP70, INO80C, KANSL1, LAS1L, MAX, MCRS1, MGA, MYST1/MOF, PELP1, PHF20, PRP31, RING2, RUVB1/TIP49A, RUVB2/TIP49B, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10. Binds to CIITA and TAF1 and inhibits their acetyltransferase activity, thereby repressing activated transcription and behaving as a repressor at these promoters.
The [KR]-[STA]-K motif is specifically recognized by the SETD7 methyltransferase, which methylates Lys-5 in vitro.
Belongs to the TAF7 family.
