Interpro abstract (IPR003923):

Transcription initiation factor TFIID is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. The complex includes TATA binding protein (TBP) and various TBP-associated factors (TAFS). TFIID is a bona fide RNA polymerase II-specific TATA-binding protein-associated factor (TAF) and is essential for viability [(PUBMED:8662725)]. This entry represents one of the TAFs, TAF10.

TFIID acts to nucleate the transcription complex, recruiting the rest of the factors through a direct interaction with TFIIB. The TBP subunit of TFIID is sufficient for TATA-element binding and TFIIB interaction, and can support basal transcription. The protein belongs to the TAF2H family.

TAF10 is part of other transcription regulatory multiprotein complexes (e.g., SAGA, TBP-free TAF-containing complex [TFTC], STAGA, and PCAF/GCN5). Several TAFs interact via histone-fold motifs. The histone fold (HFD) is the interaction motif involved in heterodimerization of the core histones and their assembly into nucleosome octamer. The minimal HFD contains three alpha-helices linked by two loops. The HFD is found in core histones, TAFs and many other transcription factors. Five HF-containing TAF pairs have been described in TFIID: TAF6-TAF9, TAF4-TAF12, TAF11-TAF13, TAF8-TAF10 and TAF3-TAF10 [(PUBMED:16858867), (PUBMED:15870280), (PUBMED:17375202)].
