Activation1

  • Ubiquitin-dependent protein disposal may preserve tissue function despite defective mitophagy

    Where this hypothesis actsDamaged long-lived proteins outside mitochondria, across multiple tissues with defective mitophagy

    What is proposedIncrease ubiquitin-dependent degradation of damaged proteins

    With whatNot stated in the record

    HowSuppress mTOR; the regulator or substrate set responsible for the additional degradation remains to be identified

    Possible resultPossible restoration of enzyme and contractile function despite persistent defective mitophagy
