RSP5-BUL1 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. Polyubiquinates plasma membrane transporters and permeases, required for their endocytosis and subsequent degradation in the vacuole. BUL1 binds to the target protein, enabling ubiquitylation by RSP5. Phosphorylation of BUL1 results in binding to 14-3-3 proteins proteins, protecting the permeases from down-regulation. Appears to be redundant with the RSP5-BUL2 ubiquitin ligase complex (CPX-2923).
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, regulation of transport
