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 RT chicken T-cell receptor alpha chain constant region."; RL Immunogenetics 46:376-382(1997). CC -!- FUNCTION: Essential subunit of the N-oligosaccharyl transferase CC (OST) complex which catalyzes the transfer of a high mannose CC oligosaccharide from a lipid-linked oligosaccharide donor to an CC asparagine residue within an Asn-X-Ser/Thr consensus motif in CC nascent polypeptide chains. N-glycosylation occurs CC cotranslationally and the complex associates with the Sec61 CC complex at the channel-forming translocon complex that mediates CC protein translocation across the endoplasmic reticulum (ER). Loss CC of the DAD1 protein triggers apoptosis (By similarity). CC {ECO:0000250}. CC -!- CATALYTIC ACTIVITY: Dolichyl diphosphooligosaccharide + [protein]- CC L-asparagine = dolichyl diphosphate + a glycoprotein with the CC oligosaccharide chain attached by N-beta-D-glycosyl linkage to a CC protein L-asparagine. CC -!- PATHWAY: Protein modification; protein glycosylation. CC -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex. CC OST seems to exist in different forms which contain at least RPN1, CC RPN2, OST48, DAD1, OSTC, KRTCAP2 and either STT3A or STT3B. OST CC can form stable complexes with the Sec61 complex or with both the CC Sec61 and TRAP complexes (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane CC {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. CC -!- SIMILARITY: Belongs to the DAD/OST2 family. {ECO:0000305}.
