General annotation (Comments)

Function	Acts as component of the general transcription and DNA repair factor IIH (TFIIH) core, which is essential for both basal and activated transcription, and is involved in nucleotide excision repair (NER) of damaged DNA. TFIIH has CTD kinase and DNA-dependent ATPase activity, and is essential for polymerase II transcription in vitro. Ref.3 Ref.4
Subunit structure	Component of the TFIIH core complex, which is composed of RAD3, SSL1, SSL2, TFB1, TFB2, TFB4 and TFB5.
Subcellular location	Nucleus.
Miscellaneous	Present with 5150 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Contains 2 BSD domains.
