SIRT3 Antibody – Goat Polyclonal

SIRT3: a soluble mitochondrial NAD-dependent protein deacetylase. Can deacetylate and thereby activate a central metabolic regulator in the mitochondrial matrix, glutamate dehydrogenase. Mitochondrial proteins are hyperacetylated in SIRT3-deficient mice, but not in SIRT4 or SIRT5 deficient mice. SIRT3-deficient mice have no obvious metabolic phenotype, and the process of adaptive thermogenesis is normal. Can deacetylate and activate isocitrate dehydrogenase 2, an enzyme that participates in regulation of the citric acid cycle and the regeneration of antioxidants. Inhibited by nicotinamide, but not by trichostatin A. Its unprocessed form is enzymatically inactive. It is processed by mitochondrial processing peptidase (MPP) in the mitochondrial matrix to give an enzymatically active 28 kDa product.
