CC -!- FUNCTION: Component of the general transcription and DNA repair factor
CC IIH (TFIIH) core complex, which is involved in general and
CC transcription-coupled nucleotide excision repair (NER) of damaged DNA
CC and, when complexed to CAK, in RNA transcription by RNA polymerase II.
CC In NER, TFIIH acts by opening DNA around the lesion to allow the
CC excision of the damaged oligonucleotide and its replacement by a new
CC DNA fragment. In transcription, TFIIH has an essential role in
CC transcription initiation. When the pre-initiation complex (PIC) has
CC been established, TFIIH is required for promoter opening and promoter
CC escape. Phosphorylation of the C-terminal tail (CTD) of the largest
CC subunit of RNA polymerase II by the kinase module CAK controls the
CC initiation of transcription. {ECO:0000250|UniProtKB:Q13889}.
CC -!- SUBUNIT: Component of the 7-subunit TFIIH core complex composed of
CC XPB/repB, XPD/repD, gtf2h1, gtf2h2, gtf2h3, gtf2h4 and gtf2h5, which is
CC active in NER. The core complex associates with the 3-subunit CDK-
CC activating kinase (CAK) module composed of cycH/cyclin H, cdk7 and
CC mnat1 to form the 10-subunit holoenzyme (holo-TFIIH) active in
CC transcription. {ECO:0000250|UniProtKB:Q13889}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the TFB4 family. {ECO:0000305}.
