ID DAD1_CHICK Reviewed; 123 AA. AC O13113; DT 15-JUL-1999, integrated into UniProtKB/Swiss-Prot. DT 01-JUL-1997, sequence version 1. DT 31-OCT-2006, entry version 31. DE Dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit DE DAD1 (EC 2.4.1.119) (Oligosaccharyl transferase subunit DAD1) DE (Defender against cell death 1) (DAD-1). GN Name=DAD1; OS Gallus gallus (Chicken). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Archosauria; Aves; Neognathae; Galliformes; Phasianidae; Phasianinae; OC Gallus. OX NCBI_TaxID=9031; RN [1] RP NUCLEOTIDE SEQUENCE [MRNA]. RX MEDLINE=97419167; 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: Component of the N-oligosaccharyl transferase enzyme CC which catalyzes the transfer of a high mannose oligosaccharide CC from a lipid-linked oligosaccharide donor to an asparagine residue CC within an Asn-X-Ser/Thr consensus motif in nascent polypeptide CC chains. N-glycosylation occurrs cotranslational and the complex CC associates with the Sec61 complex at the channel-forming CC translocon complex that mediates protein translocation across the CC endoplasmic reticulum (ER). Loss of the DAD1 protein triggers CC apoptosis (By similarity). CC -!- CATALYTIC ACTIVITY: Dolichyl diphosphooligosaccharide + protein L- CC asparagine = dolichyl diphosphate + a glycoprotein with the CC oligosaccharide chain attached by N-glycosyl linkage to protein L- CC asparagine. CC -!- SUBUNIT: Component of the oligosaccharyl transferase (OST) complex CC (By similarity). OST seems to exist in different forms which CC contain at least RPN1/ribophorin I, RPN2/ribophorin II, OST48, CC DAD1, and either STT3A or STT3B. CC -!- SUBCELLULAR LOCATION: Membrane; multi-pass membrane protein CC (Potential). CC -!- SIMILARITY: Belongs to the DAD/OST2 family.
