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 TFIIK, 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/ptr8, 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/ptr8 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 TFIIK controls the initiation of transcription (By similarity). Plays a
CC role in mRNA export (PubMed:17212653). {ECO:0000250|UniProtKB:Q00578,
CC ECO:0000269|PubMed:17212653}.
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/ptr8, XPD/rad15, ssl1, tfb1, tfb2, tfb4 and tfb5, which is active
CC in NER. The core complex associates with the 3-subunit CTD-kinase
CC module TFIIK composed of mcs2/cyclin H, mcs6/cdk7 and pmh1/tfb3 to form
CC the 10-subunit holoenzyme (holo-TFIIH) active in transcription.
CC {ECO:0000269|PubMed:14534314}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:10759889}.
CC -!- SIMILARITY: Belongs to the helicase family. RAD25/XPB subfamily.
CC {ECO:0000305}.
