RAD6-RAD18 ubiquitin ligase 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
Ubiquitin ligase complex invovled in post-replicative repair of damaged DNA. Mono-ubiquitinates PCNA at a highly conserved lysine, lys-164, in response to replication-stalling DNA damage. This promotes the recruitment of a class of specialized polymerases capable of using damaged DNA as a template for trans-lesion synthesis. Also plays a role in the prevention of spontaneous mutations caused by oxidation of guanine to 7,8-dihydo-8-oxoguanine, caused by free radicals and reactive oxygen species.
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.

DNA binding, acyltransferase activity, ion binding, transferase activity, DNA damage response, DNA metabolic process, DNA repair, protein modification by small protein conjugation or removal, response to stress
