title: Apoptosome: the cellular engine for the activation of caspase-9.
abstract: Characterization of the apoptosome by cryo-EM reveals a wheel-shaped heptameric assembly involving Apaf-1 and cytochrome c. This structure provides a framework for understanding the activation mechanisms of caspase-9, an important initiator caspase in apoptosis.
