Glycosylphosphatidylinositol-N-acetylglucosaminyltransferase 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
Monoglycosyltransferase complex that catalyses the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to the 6-position of phosphatidylinositol, the first, and committed, step of glycosylphosphatidylinositol (GPI) biosynthesis. GPI is a complex glycolipid with a core structure, phosphoethanolamine-6-mannose-alpha1,2-mannose-alpha1,6-mannose-alpha1,4-glucosamine-alpha1,6-inositol-phospholipid that functions as a membrane anchor for many cell surface proteins.
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.
