OST4
In molecular biology, OST4 (Dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit 4) is a subunit of the oligosaccharyltransferase complex.〔 〕 OST4 is a very short, approximately 30 amino acids, protein found from fungi to vertebrates. It appears to be an integral membrane protein that mediates the en bloc transfer of a pre-assembled high-mannose oligosaccharide onto asparagine residues of nascent polypeptides as they enter the lumen of the rough endoplasmic reticulum.〔 〕〔 〕 ==References==
