Fas (CD95) is a cell surface receptor that belongs to the tumor necrosis factor receptor (TNFR) superfamily. It plays a pivotal role in inducing apoptosis when bound by its ligand, FasL. Upon activation, Fas triggers a cascade of intracellular signals leading to the formation of the death-inducing signaling complex (DISC). This complex ultimately results in the activation of caspases, the enzymes responsible for executing apoptosis.
