Transcription by RNA polymerase II: a process linked to DNA repair.
The proteins that are implicated in the basal transcription of protein coding genes have now been identified. Although little is known about their function, recent data demonstrate the ability of these proteins, previously called class II transcription factors, to participate in other reactions: TBP, the TATA-box binding factor, is involved in class I and III transcription, while TFIIH has been shown to possess components that are involved in the DNA repair mechanism. The involvement of some if not all of the TFIIH subunits in transcription and repair may explain the heterogeneity of the various and sometimes completely unrelated symptoms observed in xeroderma pigmentosum, Cockayne Syndrome and trichothiodystrophy disorders.
