SCF-Grr1 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
SCF-Grr1 is a member of the SCF (Skp1-Cullin-F-box) E3 ubiquitin ligase family, in which the F-box protein, Grr1, forms the substrate recognition subunit. It is required for the G1/S cell cycle transition, when it ubiquitinates and targets proteins such as CLN1/2 and GIC2 for degradation. It is a central component in glucose-induced signal transduction, regulating the induction of the glucose transporter Hxt1 via degradation of Mth1 when glucose is abundant. Grr1 is also responsible for the ubiquitination and degradation of several metabolic enzymes and proteins involved in glycolysis and amino-acid biosynthesis.The active complex may be a homodimer.
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, proteolysis involved in protein catabolic process, regulation of transport
