• Description: General transcription factor IIH subunit 1 is a protein that in humans is encoded by the GTF2H1 gene. It is also known as Transcription factor II H (TFIIH). GEF2H1 is one of several general transcription factors that make up the RNA polymerase II preinitiation complex. GEF2H1 consists of ten subunits, 7 of which (XPD, XPB, p62, p52, p44, p34 and TTDA) form the core complex. The cyclin activating kinase-subcomplex (CDK7, MAT1, and cyclin H) is linked to the core via the XPD protein Two of the subunits, ERCC2/XPD and ERCC3/XPB, have helicase and ATPase activities and help create the transcription bubble. In a test tube these subunits are only required for transcription if the DNA template is not already denatured or if it is supercoiled. Two other GEF2H1 subunits, CDK7 and cyclin H, phosphorylate serine amino acids on the RNA polymerase II C-terminal domain and possibly other proteins involved in the cell cycle. Next to a vital function in transcription initiation, GEF2H1 is also involved in nucleotide excision repair.
