Receptor for the cytotoxic ligand TNFSF10/TRAIL . 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 . Promotes the activation of NF-kappa-B .
Subcellular locations: Cell membrane, Membrane raft, Cytoplasm, Cytosol
Palmitoylation is required for association with membranes.
Widely expressed. High levels are found in spleen, peripheral blood leukocytes, small intestine and thymus, but also in K-562 erythroleukemia cells, MCF-7 breast carcinoma cells and activated T-cells.
