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. Diseases associated with DAD1 include Ogden Syndrome and Granulomatous Disease, Chronic, Autosomal Recessive, 1. Among its related pathways are Protein processing in endoplasmic reticulum and N-Glycan biosynthesis. Gene Ontology (GO) annotations related to this gene include dolichyl-diphosphooligosaccharide-protein glycotransferase activity and oligosaccharyl transferase activity.
UniProtKB/Swiss-Prot Summary for DAD1 Gene
Subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation (PubMed:22467853). 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). All subunits are required for a maximal enzyme activity (By similarity). Required for the assembly of both SST3A- and SS3B-containing OST complexes. Loss of the DAD1 protein triggers apoptosis (PubMed:22467853).
