Protein

Transcription initiation factor TFIID subunit 7

Gene

TAF7

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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).

Interactioni

Subunit structurei

TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). 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.2 Publications

Miscellaneousi

Miscellaneous

Overexpression of TAF7 in HeLa cells inhibits cyclin D1 and cyclin A gene transcription and causes the cells to accumulate in early S phase. In contrast, depletion of TAF7 from TFIID complexes by siRNAs increases histone H3 acetylation at both cyclin promoters and stimulates cyclins CCND1 and CCNA gene transcription.
