CC -!- FUNCTION: ATP-dependent 3'-5' DNA helicase, component of the general
CC transcription and DNA repair factor IIH (TFIIH) core complex, which is
CC involved in general and transcription-coupled nucleotide excision
CC repair (NER) of damaged DNA and, when complexed to CAK, in RNA
CC transcription by RNA polymerase II. In NER, TFIIH acts by opening DNA
CC around the lesion to allow the excision of the damaged oligonucleotide
CC and its replacement by a new DNA fragment. The ATPase activity of
CC XPB/ERCC3, but not its helicase activity, is required for DNA opening.
CC In transcription, TFIIH has an essential role in transcription
CC initiation. When the pre-initiation complex (PIC) has been established,
CC TFIIH is required for promoter opening and promoter escape. The ATP-
CC dependent helicase activity of XPB/ERCC3 is required for promoter
CC opening and promoter escape. Phosphorylation of the C-terminal tail
CC (CTD) of the largest subunit of RNA polymerase II by the kinase module
CC CAK controls the initiation of transcription.
CC {ECO:0000250|UniProtKB:P19447}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC -!- SUBUNIT: Component of the 7-subunit TFIIH core complex composed of
CC XPB/ERCC3, XPD/ERCC2, GTF2H1, GTF2H2, GTF2H3, GTF2H4 and GTF2H5, which
CC is active in NER. The core complex associates with the 3-subunit CDK-
CC activating kinase (CAK) module composed of CCNH/cyclin H, CDK7 and
CC MNAT1 to form the 10-subunit holoenzyme (holo-TFIIH) active in
CC transcription. Interacts with PUF60. Interacts with ATF7IP. Interacts
CC with KAT2A; leading to KAT2A recruitment to promoters and acetylation
CC of histones. {ECO:0000250|UniProtKB:P19447}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the helicase family. RAD25/XPB subfamily.
CC {ECO:0000305}.
