Parkin-dependent mitophagy occurs via proteasome-dependent steps sequentially targeting separate mitochondrial sub-compartments for autophagy

Abstract excerpt

PINK1/parkin-dependent mitophagy initially involves (phospho)ubiquitin-directed proteasome-dependent degradation of certain outer mitochondrial membrane (OMM) proteins (e.g. mitofusins) and the recruitment of autophagy adaptors to a group of ubiquitinated OMM proteins, eventually leading to autophagic removal of damaged mitochondria in stressed cells. Here we provide evidence that mitochondrial degradation occurs...
