Dolichyl-diphosphooligosaccharide–protein glycosyltransferase subunit 1 is an enzyme that in humans is encoded by the RPN1 gene.This gene encodes a type I integral ribophorin 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.
