Previous GeneCards Identifiers for DAD1 Gene
DAD1, the defender against apoptotic cell death, was initially identified as a negative regulator of programmed cell death in the temperature sensitive tsBN7 cell line. The DAD1 protein disappeared in temperature-sensitive cells following a shift to the nonpermissive temperature, suggesting that loss of the DAD1 protein triggered apoptosis. DAD1 is believed to be a tightly associated subunit of oligosaccharyltransferase both in the intact membrane and in the purified enzyme, thus reflecting the essential nature of N-linked glycosylation in eukaryotes.

GeneCards Summary for DAD1 Gene
DAD1 (Defender Against Cell Death 1) is a Protein Coding gene. Among its related pathways are Metabolism and N-Glycan biosynthesis. GO annotations related to this gene include dolichyl-diphosphooligosaccharide-protein glycotransferase activity and oligosaccharyl transferase activity.
UniProtKB/Swiss-Prot for DAD1 Gene
Essential subunit of the N-oligosaccharyl transferase (OST) complex which catalyzes the transfer of a high mannose oligosaccharide from a lipid-linked oligosaccharide donor to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains. N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). Loss of the DAD1 protein triggers apoptosis (By similarity).
