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 TFIIK, in RNA transcription by RNA polymerase
CC II. 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 TFIIK controls the
CC initiation of transcription. {ECO:0000269|PubMed:7961739,
CC ECO:0000269|PubMed:8631896, ECO:0000269|PubMed:9235928}.
CC -!- SUBUNIT: Component of the 7-subunit TFIIH core complex composed of
CC XPB/SSL2, XPD/RAD3, SSL1, TFB1, TFB2, TFB4 and TFB5, which is active in
CC NER. The core complex associates with the 3-subunit CTD-kinase module
CC TFIIK composed of CCL1, KIN28 and TFB3 to form the 10-subunit
CC holoenzyme (holo-TFIIH) active in transcription (PubMed:7961739,
CC PubMed:14500720, PubMed:9235928). Interacts with TFB5
CC (PubMed:19172752). {ECO:0000269|PubMed:14500720,
CC ECO:0000269|PubMed:19172752, ECO:0000269|PubMed:7961739,
CC ECO:0000269|PubMed:9235928}.
CC -!- INTERACTION:
CC Q02939; Q3E7C1: TFB5; NbExp=6; IntAct=EBI-2345544, EBI-2095127;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- MISCELLANEOUS: Present with 8900 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the TFB2 family. {ECO:0000305}.
