Cytochrome c-mediated apoptotic response

Stable Identifier
Homo sapiens
Locations in the PathwayBrowser

Upon its release from the mitochondrial intermembrane space, Cytochrome c binds to and causes a conformational change in the cytoplasmic protein Apaf1. This conformational change allows the Cytochrome c:Apaf1 complex to associate with ATP triggering oligomerization of the Apaf1:Cytochrome c:ATP complex. The apoptosome then associates with Procaspase-9 resulting in the formation of the active caspase-9 holoenzyme which functions in cleaving effector caspases.
