Summaries for RPN1 Gene

Entrez Gene Summary for RPN1 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 forms part of the regulatory subunit of the 26S proteasome and may mediate binding of ubiquitin-like domains to this proteasome. [provided by RefSeq, Jul 2008]

GeneCards Summary for RPN1 Gene

RPN1 (Ribophorin I) is a Protein Coding gene. Diseases associated with RPN1 include Acute Myeloid Leukemia With Inv3(P21;Q26.2) Or T(3;3)(P21;Q26.2). Among its related pathways are Protein processing in endoplasmic reticulum and N-Glycan biosynthesis. Gene Ontology (GO) annotations related to this gene include dolichyl-diphosphooligosaccharide-protein glycotransferase activity.

UniProtKB/Swiss-Prot for RPN1 Gene

  • Essential subunit of the N-oligosaccharyl transferase (OST) complex which catalyzes the transfer of a high mannose oligosaccharide from a lipid-linked oligosaccharide donor to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains.
