mi·to·chon·dri·al mem·brane

(mī'tō-kon'drē-ăl mem'brān)
The mitochondrion has two membranes: the inner where the electron transport system is located and the outer, which acts as a gatekeeper and allows only certain molecules to enter.

It is well known that PINK1/Parkin signaling is the classical mediator of mitophagy; however, emerging review suggested that the colocalization of PINK1 and Mfn-2 at the outer mitochondrial membrane provided an opportunity for PINK1 to phosphorylate Mfn-2, which is necessary for mitophagic Parkin binding to mitochondria [28].
These proteins leak into the cytoplasm when an apoptotic signal permeabilizes the mitochondrial membrane. Subsequently, released cytochrome c binds apoptotic protease-activating factor-1 (Apaf-1) in the presence of ATP, thereby inducing apoptosis by activating caspases 9 and 3, initiator and apoptotic caspases, respectively.
