Popis: Apoptotic initiator caspases are thought to be activated through homodimerization but this remains controversial. Here the authors demonstrate that caspase-9 can adopt two distinct conformations within the Apaf-1 apoptosome, each with distinct properties that contribute to the overall function of the complex.
