A history of TFIIH: two decades of molecular biology on a pivotal transcription/repair factor.

Abstract excerpt

The TFIIH multiprotein complex is organized into a 7-subunit core associated with a 3-subunit CDK-activating kinase module (CAK). Three enzymatic subunits are present in TFIIH, two ATP-dependent DNA helicases: XPB and XPD, and the kinase Cdk7. Mutations in three of the subunits, XPB, XPD and TTDA, lead to three distinct genetic disorders: xeroderma pigmentosum (XP), Cockayne syndrome (CS) and trichothiodystrophy...
