SIRT3 (sirtuin 3) is a NAD⁺-dependent deacetylase belonging to the sirtuin family, primarily localized in mitochondria. It plays a pivotal role in regulating energy metabolism, antioxidant defense, and mitochondrial homeostasis by modifying acetylation states of target proteins. SIRT3 activates key metabolic enzymes (e.g., ACSS2. SOD2) and modulates pathways critical for fatty acid oxidation, oxidative phosphorylation, and reactive oxygen species (ROS) scavenging. Its activity is linked to lifespan extension, stress resistance, and metabolic adaptation in response to caloric restriction.
Recombinant SIRT3 protein is engineered through heterologous expression systems (e.g., E. coli or mammalian cells) for in vitro studies. The purified protein retains deacetylase activity and is widely used to investigate molecular mechanisms of mitochondrial regulation, aging-related diseases, and metabolic disorders. Researchers employ it to screen activators/inhibitors, study post-translational modifications, or validate interactions with substrates. Its applications extend to modeling neurodegenerative, cardiovascular, and cancer-related pathologies where SIRT3 dysregulation is implicated. Current studies focus on harnessing SIRT3's therapeutic potential, particularly in metabolic syndrome and age-associated decline. Recombinant SIRT3 serves as a vital tool for decoding mitochondrial biology and developing precision therapies.
