Cardiolipin in apoptosis and mitophagy. (A) CL is necessary for the recruitment of LC3, which mediates binding of the phagophore membrane. (B) The role of CL in the processing of procaspase-8 is shown. Caspase-8-mediated processing of Bid to form t-Bid is stimulated by CL. Formation of t-Bid is required for the CL dependent oligomerization of Bax and Bak. Cytochrome c is detached from oxidized CL and released into the cytosol. OM, outer membrane; IM, inner membrane; IMS, intermembrane space.
