Basic Information of Protein
UniProt ID OST48_HUMAN
UniProt AC P39656
Protein Name Dolichyl-diphosphooligosaccharide--protein glycosyltransferase 48 kDa subunit
Gene Name DDOST
Organism Homo sapiens (Human).
Sequence Length 456
Subcellular Localization Endoplasmic reticulum membrane
Single-pass type I membrane protein .
Protein Description Essential subunit of the N-oligosaccharyl transferase (OST) complex 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. Required for the assembly of both SST3A- and SS3B-containing OST complexes. Required for efficient N-glycosylation..
