TRAIL-R1 (DR4; CD261) is a receptor for the cytotoxic ligand 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-kappaB.
Sequence:The extracellular domain of human TRAIL-R1 (aa 24-239) is fused to the Fc portion of human IgG1.
