Abstract excerpt
Some members of the inhibitor of apoptosis (IAP) family suppress apoptosis by neutralizing caspases. The current model suggests that all caspase-regulatory IAPs function as direct enzyme inhibitors, blocking effector caspases by binding to their catalytically active pockets. Here we show that IAPs are functionally non-equivalent and regulate effector caspases through distinct mechanisms. Whereas XIAP binds...
