Comments

Comment Type Description
Catalytic Activity Dolichyl diphosphooligosaccharide + [protein]- L-asparagine = dolichyl diphosphate + a glycoprotein with the oligosaccharide chain attached by N-beta-D-glycosyl linkage to a protein L-asparagine.
Function 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.
Pathway Protein modification; protein glycosylation.
Similarity Belongs to the OST1 family
Subcellular Location Endoplasmic reticulum membrane; Single-pass type I membrane protein. Melanosome .
Subunit 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 (By similarity)
Tissue Specificity Expressed in all tissues tested.
