Park2/Parkin is a central mediator of selective mitochondrial autophagy for mitochondrial
quality control. We showed in mouse hearts that PINK1/Mfn2/Park2 mediated generalized
mitophagy is essential to the normal perinatal transition from fetal mitochondria that prefer
carbohydrates as metabolic substrates to adult fatty-acid metabolizing mitochondria. Our
findings demonstrate how functional interactions between mitophagic mitochondrial removal
and biogenic mitochondrial replacement facilitate metabolic maturation of the heart.
