CC -!- FUNCTION: Subunit of the oligosaccharyl transferase (OST) complex that
CC catalyzes the initial transfer of a defined glycan
CC (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-
CC pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr
CC consensus motif in nascent polypeptide chains, the first step in
CC protein N-glycosylation (PubMed:15860005). N-glycosylation occurs
CC cotranslationally and the complex associates with the Sec61 complex at
CC the channel-forming translocon complex that mediates protein
CC translocation across the endoplasmic reticulum (ER). All subunits are
CC required for a maximal enzyme activity (By similarity).
CC {ECO:0000250|UniProtKB:P33767, ECO:0000269|PubMed:15860005}.
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex.
CC {ECO:0000250|UniProtKB:P33767}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Single-pass type I membrane protein {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Embryo-lethal. {ECO:0000269|PubMed:15860005}.
CC -!- SIMILARITY: Belongs to the DDOST 48 kDa subunit family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAA97274.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
