GPI-anchor transamidase 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.

Transamidase enzyme complex that transfers the glycosylphosphatidylinositol (GPI) lipid to the newly made GPI protein in the endoplasmic reticulum, replacing the C-terminal GPI attachment signal peptide of a protein with the lipid. 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.

hydrolase activity, peptidase activity, cell wall organization or biogenesis, membrane
