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 Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include dolichyl-diphosphooligosaccharide-protein glycotransferase activity.

    Quaternary structure:
    • Component of the oligosaccharyltransferase (OST) complex. OST seems to exist in different forms which contain at least RPN1, RPN2, OST48, DAD1, OSTC, KRTCAP2 and either STT3A or STT3B. OST can form stable complexes with the Sec61 complex or with both the Sec61 and TRAP complexes. Also identified as part of a complex which includes CANX, DERL1, DERL2, DDOST/OST48, RPN1, RPN2, SELK, VIMP, STT3A AND VCP. This contains known members of the OST complex and may be a form of this complex.
