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:Q99380}.
CC -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex.
CC {ECO:0000250|UniProtKB:Q99380}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Single-pass type III membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the OST4 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAH92182.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
