Receptor for the cytotoxic ligand TNFSF10/TRAIL (PubMed:26457518, PubMed:38532423). The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis (PubMed:19090789). Promotes the activation of NF-kappa-B (PubMed:9430227). {ECO:0000269|PubMed:19090789, ECO:0000269|PubMed:38532423, ECO:0000269|PubMed:9430227}. This is the function of Ensembl gene identifier ENSG00000104689 (TNFRSF10A, TNF receptor superfamily member 10a).
