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. N-glycosylation occurs cotranslationally and
CC       the complex associates with the Sec61 complex at the channel-forming
CC       translocon complex that mediates protein translocation across the
CC       endoplasmic reticulum (ER). All subunits are required for a maximal
CC       enzyme activity. {ECO:0000250|UniProtKB:P46964}.
CC   -!- PATHWAY: Protein modification; protein glycosylation.
CC   -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex.
CC       {ECO:0000250|UniProtKB:P46964}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC       Multi-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the DAD/OST2 family. {ECO:0000305}.
