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.
