Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| comment | FUNCTION 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:10438527, PubMed:33795473). TAF7 forms a promoter DNA binding subcomplex of TFIID, together with TAF1 and TAF2 (PubMed:33795473). Part of a TFIID complex containing TAF10 (TFIID alpha) and a TFIID complex lacking TAF10 (TFIID beta) (PubMed:10438527).SUBUNIT Component of the TFIID basal transcription factor complex, composed of TATA-box-binding protein TBP, and a number of TBP-associated factors (TAFs), including TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13 (PubMed:10438527, PubMed:27007846, PubMed:33795473). 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 (PubMed:27007846, PubMed:33795473). Interacts with TAF1; the interaction is direct (PubMed:25412659). Interacts with TAF1, TAF5, TAF11, TAF12, and TAF13, but not with TAF10 or TBP (PubMed:10438527, PubMed:8702684). 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 BACC1, 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 (PubMed:15960975). Interacts with CIITA and TAF1 and inhibits their acetyltransferase activity, and behaving as a repressor of CIITA- and TAF1-regulated promoters (PubMed:11592977, PubMed:20937824).INTERACTION Ubiquitous.DOMAIN The [KR]-[STA]-K motif is specifically recognized by the SETD7 methyltransferase, which methylates Lys-5 in vitro.PTM Phosphorylated by CIITA. Phosphorylation at Ser-264 by TAF1 in early G1 phase disrupts binding to TAF1.PTM Ubiquitinated by TRIM26; leading to proteasomal degradation.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.SIMILARITY Belongs to the TAF7 family. |
