The E3 ubiquitin ligase Parkin mediates the clearance of depolarized mitochondria through the autophagy pathway. PINK1 kinase activity is required for Parkin translocation to depolarized mitochondria where Parkin generates polyubiquitin chains on the voltage-dependent anion channel (VDAC1) to recruit the autophagic adaptor p62/SQSTM1.
