Fas is a cell-surface receptor molecule that relays apoptotic (cell death) signals into cells. When Fas is activated by the binding of its ligand, the proteolytic protein caspase-8 is recruited to a signalling complex known as DISC by binding to a Fas-associated adapter protein. A large new protein, FLASH, has now been identified. This protein contains a motif with oligomerizing activity and another domain (DRD domain) that interacts with a death-effector domain in caspase-8 or in the adapter protein. Stimulated Fas binds FLASH, so FLASH is probably a component of the DISC signalling complex. FLASH is therefore necessary for the activation of caspase-8 in Fas-mediated apoptosis.
