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:0000256|ARBA:ARBA00002791}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000256|ARBA:ARBA00004477}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004477}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the OST3/OST6 family.
CC {ECO:0000256|ARBA:ARBA00009561}.
