Signaling pathway of TNF-R1. Dashed grey lines represent multiple steps
The death-inducing signaling complex or DISC is a multi-protein complex formed by members of the "death receptor" family of apoptosis-inducing cellular receptors. A typical example is FasR, which forms the DISC upon trimerization as a result of its ligand (FasL) binding. The DISC is composed of the death receptor, FADD, and caspase 8. It transduces a downstream signal cascade resulting in apoptosis.
