Comments
Comment typeDescription
Catalytic ActivityDolichyl diphosphooligosaccharide + [protein]- L-asparagine = dolichyl diphosphate + a glycoprotein with the oligosaccharide chain attached by N-beta-D-glycosyl linkage to a protein L-asparagine.
FunctionInvolved in protein glycosylation. Either required for the assembly of the oligosaccharyl transferase (OTase) complex or required in substoichiometric amounts for OTase activity (By similarity). {ECO:0000250}.
PathwayProtein modification; protein glycosylation.
SimilarityBelongs to the STT3 family. {ECO:0000305}.
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
SubunitComponent of the oligosaccharyltransferase (OST) complex. {ECO:0000250}.
