MUB1-RAD6-UBR2 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. Ubiquitylates, and targets for destruction, the RPN4 (Q03465) transcription factor, which upregulates the proteasome genes. The binding of MUB1 may position the RPN4 ubiquitylation site proximal to the Ub∼RAD6 thioester and allowing the transfer of Ubiquitin from RAD6 to RPN4. MUB1 is a short-lived protein and is ubiquitinated by the UBR2-RAD6 ubiquitin conjugating enzyme (CPX-2935).
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.

acyltransferase activity, transferase activity, catabolic process, protein modification by small protein conjugation or removal, proteolysis involved in protein catabolic process
