  • PubMed Abstract: 

    In the initial stages of Fas-mediated apoptosis the cysteine protease caspase-8 is recruited to the cell receptor as a zymogen (procaspase-8) and is incorporated into the death-signalling complex. Procaspase-8 is subsequently activated leading to a cascade of proteolytic events, one of them being the activation of caspase-3, and ultimately resulting in cell destruction. Variations in the substrate specificity of different caspases have been reported.
