Summaries for OST4 Gene

GeneCards Summary for OST4 Gene

OST4 (Oligosaccharyltransferase Complex Subunit 4, Non-Catalytic) is a Protein Coding gene.

UniProtKB/Swiss-Prot for OST4 Gene

  • Acts as component 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. Required for efficient N-glycosylation. Specifically involved in maintaining stability of STT3A-containing OST complexes.

    37 amino acids
    Molecular mass:
    4193 Da
    Quaternary structure:
    • Component of the oligosaccharyltransferase (OST) complex. OST exists in two different complex forms which contain common core subunits RPN1, RPN2, OST48, OST4, DAD1 and TMEM258, either STT3A or STT3B as catalytic subunits, and form-specific accessory subunits. OST can form stable complexes with the Sec61 complex or with both the Sec61 and TRAP complexes.
