General annotation (Comments)

Function

Essential subunit of N-oligosaccharyl transferase enzyme which catalyzes the transfer of a high mannose oligosaccharide 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.

Pathway

Protein modification; protein glycosylation.

Subunit structure

Component of the oligosaccharyltransferase (OST) complex By similarity.

Subcellular location

Endoplasmic reticulum membrane; Single-pass type I membrane protein Potential.

Sequence similarities

Belongs to the DDOST 48 kDa subunit family.
