GTF2H2

Intracellular

Low cell type specificity

Low immune cell specificity

Cell line enhanced (Daudi, RPTEC TERT1)

Component of the 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 and ERCC3 (PubMed:27193682). Component of the 7-subunit TFIIH core complex composed of XPB/ERCC3, XPD/ERCC2, GTF2H1, GTF2H2, GTF2H3, GTF2H4 and GTF2H5, which is active in NER. The core complex associates with the 3-subunit CDK-activating kinase (CAK) module composed of CCNH/cyclin H, CDK7 and MNAT1 to form the 10-subunit holoenzyme (holo-TFIIH) active in transcription (PubMed:9852112, PubMed:11319235). Interacts with XPB, XPD, GTF2H1 and GTF2H3 (PubMed:11319235). (Microbial infection) Interacts with varicella-zoster virus IE63 protein.
