General transcription factor TFIIH complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.

Summary
A general transcription factor which plays a central role in both RNA polymerase II transcription and DNA repair. Component of the Pol II preinitiation complex. The TFIIH subunit XPB is an ATP-dependent translocase that promotes DNA strand separation and promoter escape. During the transition from initiation to promoter clearance, the kinase subunit Kin28 phosphorylates Ser-5 and Ser-7 within the Pol II carboxyl terminal domain (CTD). This phosphorylation initiates a cascade of phosphorylation/dephosphorylation events on the CTD that correlates with dissociation of Pol II from the initiation machinery and its association with elongation and mRNA processing factors. This is the only general transcription factor with enzyme activity. During nucleotide excision repair, TFIIH is required for opening DNA around lesions that disrupt base pairing to permit excision of the damaged DNA and its replacement by a new DNA fragment.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.

kinase activity, transferase activity, DNA damage response, DNA metabolic process, DNA repair, DNA-templated transcription initiation, biosynthetic process, protein phosphorylation, response to stress

Biological Process

Manually curated GO annotations reflect our best understanding of the basic biological process for this protein complex. Manually curated annotations are assigned by curators based on published papers when available, or by curatorial statements if necessary. Curators periodically review all manually curated GO annotations for accuracy and completeness.

Shared Annotations

This diagram displays Gene Ontology terms (green) that are shared between the given macromolecular complex (black) and other yeast complexes (yellow). Note: No diagram is shown ("No shared annotations") if there are less than 2 shared GO annotations between this complex and any other complexes.
