The TFIID basal transcription factor complex plays a major role in the initiation of RNA polymerase II (Pol II)-dependent transcription (PubMed:33795473). TFIID recognizes and binds promoters with or without a TATA box via its subunit TBP, a TATA-box-binding protein, and promotes assembly of the pre-initiation complex (PIC) (PubMed:33795473). The TFIID complex consists of TBP and TBP-associated factors (TAFs), including TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13 (PubMed:33795473). TAF10 is also component of the PCAF histone acetylase complex, the TATA-binding protein-free TAF complex (TFTC) and the STAGA transcription coactivator-HAT complex (PubMed:10373431, PubMed:11564863, PubMed:12601814, PubMed:18206972, PubMed:9885574). May regulate cyclin E expression (By similarity). {ECO:0000250|UniProtKB:Q8K0H5, ECO:0000269|PubMed:10373431, ECO:0000269|PubMed:11564863, ECO:0000269|PubMed:12601814, ECO:0000269|PubMed:18206972, ECO:0000269|PubMed:33795473, ECO:0000269|PubMed:9885574}. This is the function of TAF10 (TATA-box binding protein associated factor 10, ENSG00000166337).
