Previous GeneCards Identifiers for RPN2 Gene
This gene encodes a type I integral membrane protein found only in the rough endoplasmic reticulum. The encoded protein is part of an N-oligosaccharyl transferase complex that links high mannose oligosaccharides to asparagine residues found in the Asn-X-Ser/Thr consensus motif of nascent polypeptide chains. This protein is similar in sequence to the yeast oligosaccharyl transferase subunit SWP1. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

RPN2 (Ribophorin II) is a Protein Coding gene. Diseases associated with RPN2 include Encephalitozoonosis and Microsporidiosis. Among its related pathways are Viral mRNA Translation and Transport to the Golgi and subsequent modification. Gene Ontology (GO) annotations related to this gene include ribosome binding and dolichyl-diphosphooligosaccharide-protein glycotransferase activity.
UniProtKB/Swiss-Prot Summary for RPN2 Gene
Subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). All subunits are required for a maximal enzyme activity.
