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. Required for the assembly of both CC SST3A- and SS3B-containing OST complexes. Required for efficient CC N-glycosylation. Loss of the DAD1 protein triggers apoptosis. CC {ECO:0000250|UniProtKB:P61803}. CC -!- PATHWAY: Protein modification; protein glycosylation. CC -!- SUBUNIT: Component of the oligosaccharyltransferase (OST) complex. CC OST exists in two different complex forms which contain common CC core subunits RPN1, RPN2, OST48, OST4, DAD1 and TMEM258, either CC STT3A or STT3B as catalytic subunits, and form-specific accessory CC subunits. OST can form stable complexes with the Sec61 complex or CC with both the Sec61 and TRAP complexes (By similarity). CC {ECO:0000250|UniProtKB:P61803}. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass CC membrane protein {ECO:0000305}. CC -!- SIMILARITY: Belongs to the DAD/OST2 family. {ECO:0000305}.
