Oligosaccharyltransferase complex, OST3 variant 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
Transfers the dolicholphosphate-linked core oligosaccharide to selected Asn-X-Ser/Thr sequences of the nascent polypeptide chain, a key step in N-glycosylation of secretory and membrane-bound proteins in the lumen of the endoplasmic reticulum. The two variant complexes may be involved in the recognition of different protein substrates, perhaps in combination with their recruitment to the two different protein translocation machineries. Variant 2 binds to SEC61 translocon complex (CPX-1833).
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.
