Background
SIRT3 (Sirtuin-3) is mitochondrially-targeted NAD+-dependent deacetylase family protein mediating matrix-protein deacetylation to modulate oxidative phosphorylation, antioxidant defence and metabolic reprogramming. SIRT3 precursor is translated in cytosol, imported into mitochondrial matrix and proteolytically processed into active form. It deacetylates respiratory-complex subunits, IDH2, SOD2 and other matrix proteins, boosting mitochondrial antioxidant capacity and tuning TCA-cycle and fatty-acid oxidation. SIRT3 mitigates ROS burden and sustains mitochondrial homeostasis; its expression declines in ageing and metabolic disorders. In tumors SIRT3 exerts dual effects: it counteracts oxidative genome damage yet can sustain oncogenic metabolism.
