General Information
Term transcription factor TFIIH core complex ID (Ontology) GO:0000439 (Gene Ontology)
Definition The 7 subunit core of TFIIH that is a part of either the general transcription factor holo-TFIIH or the nucleotide-excision repair factor 3 complex. In S. cerevisiae/humans the complex is composed of: Ssl2/XPB, Tfb1/p62, Tfb2/p52, Ssl1/p44, Tfb4/p34, Tfb5/p8 and Rad3/XPD.[ PubMed:14500720 PubMed:17215295 PubMed:22308316 PubMed:22572993 PubMed:23028141 PubMed:7813015 ]
Also Known As"core TFIIH complex" ; "SSL2-core TFIIH complex"
