Target data 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). TAF1 is the largest component and core scaffold of the TFIID complex, involved in nucleating complex assembly (PubMed : 25412659, PubMed : 27007846, PubMed : 33795473). TAF1 forms a promoter DNA binding subcomplex of TFIID, together with TAF7 and TAF2 (PubMed : 33795473). Contains novel N- and C-terminal Ser/Thr kinase domains which can autophosphorylate or transphosphorylate other transcription factors (PubMed : 25412659, PubMed : 8625415). Phosphorylates TP53 on 'Thr-55' which leads to MDM2-mediated degradation of TP53 (PubMed : 25412659). Phosphorylates GTF2A1 and GTF2F1 on Ser residues (PubMed : 25412659). Possesses DNA-binding activity (PubMed : 25412659). Essential for progression of the G1 phase of the cell cycle (PubMed : 11278496, PubMed : 15053879, PubMed : 2038334, PubMed : 8450888, PubMed : 8625415, PubMed : 9660973, PubMed : 9858607). Exhibits histone acetyltransferase activity towards histones H3 and H4 (PubMed : 15870300). See full target information TAF1
