General annotation (Comments)
| Function | Essential subunit of N-oligosaccharyl transferase enzyme 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. |
| Catalytic activity | Dolichyl diphosphooligosaccharide + protein L-asparagine = dolichyl diphosphate + a glycoprotein with the oligosaccharide chain attached by N-glycosyl linkage to protein L-asparagine. |
| Subunit structure | Component of the oligosaccharyl transferase (OST) complex. OST seems to exist in different forms which contain at least RPN1/ribophorin-1, RPN2/ribophorin-2, OST48, DAD1, and either STT3A or STT3B. |
| Subcellular location | Endoplasmic reticulum membrane; Multi-pass membrane proteinPotential. |
| Tissue specificity | Expressed in all tissues tested. |
| Sequence similarities | Belongs to the SWP1 family. |
