Mitochondrial protein import and assembly dynamics in response to chronic contractile activity in skeletal muscle of young and aged animals

Mitochondrial protein import adapts to perturbations in cellular energy status by altering the rate at which nuclear‐encoded proteins are translocated into mitochondria. The purposes of this study were to determine whether the import and assembly of precursor proteins are similar in muscle from young and aged F344XBN animals, and to assess the effect of chronic contractile activity (CCA) on the import pathway in subsarcolemmal (SS) …
