Asi 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
The Asi complex resides in the nuclear inner membrane and ubiquitinates proteins to target them for degradation, as part of the endoplasmic reticulum-associated degradation (ERAD) pathway. It targets two types of substrate: misfolded nuclear inner membrane proteins; and proteins that participate in sterol biosynthesis, including ERG11 (lanosterol 14-alpha-demethylase) and NSG1, a regulator of sterol biosynthesis. The Asi complex has an important role in regulation of the response to extracellular amino acids, by mediating degradation of the transcription factor Stp1.
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, response to chemical, membrane
