Carboxy-terminal domain protein kinase 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
Cyclin-dependent protein that phosphorylates RNA polymerase II (RNAPII, CPX-2662) on the carboxyl-terminal repeat domain (CTD) of its largest subunit RPB1 (P04050), which is important for efficient transcription elongation, mRNA 3′-end processing, and transcription termination of small noncoding RNAs. Also plays a role in RNA polymerase I (RNAPI, CPX-1664) transcription. Increases the correct decoding of mRNA during translation elongation by phosphorylating residue Ser-238 of RPS2 (P25443), a protein of the small ribosomal subunit (CPX-1599). Directs the association of SET2 (P46995) to RNAP II, which results in the establishment of H3K36 methylation and deacetylated chromatin in the bodies of genes. Also regulates SET1-mediated H3K4 methylation which marks the 5′ end of transcribed genes, promoting association of chromatin-remodeling and histone-modifying enzymes.
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.
