RX PubMed=9271627; DOI=10.1007/s002510050291; RA Wang K., Gan L., Kuo C.L., Hood L.; RT "A highly conserved apoptotic suppressor gene is located near the chicken RT T-cell receptor alpha chain constant region."; RL Immunogenetics 46:376-382(1997). 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:E2R4X3}. CC -!- PATHWAY: Protein modification; protein glycosylation. CC -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex. CC {ECO:0000250|UniProtKB:E2R4X3}. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass CC membrane protein {ECO:0000305}. CC -!- SIMILARITY: Belongs to the DAD/OST2 family. {ECO:0000305}.
