Insights from inherited forms of parkinsonism suggest that insufficient mitophagy may be one etiology of the disease. PINK1/Parkin-dependent mitophagy, which helps maintain a healthy mitochondrial network, is initiated by activation of the PINK1 kinase specifically on damaged mitochondria. Recent investigation of this process reveals that import of PINK1 into mitochondria is regulated and yields a stress-sensing mechanism. In this review, we focus on the mechanisms of mitochondrial stress-dependent PINK1 activation that is exerted by regulated import of PINK1 into different mitochondrial compartments and how this offers strategies to pharmacologically activate the PINK1/Parkin pathway.
