This protein is mostly found in the mitochondria where it regulates the acetylation state of various substrates. It plays an important role in maintaining mitochondrial homeostasis by modifying protein activity. SIRT3 is evolutionarily conserved and highly expressed in tissues with high energy demand like the heart liver and brown adipose tissue.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nSIRT3 modulates energy homeostasis by deacetylating and regulating enzymes involved in metabolism. It is a part of the mitochondrial sirtuin family contributing to fatty acid oxidation and the antioxidant defense system. By targeting key metabolic enzymes SIRT3 directly impacts the tricarboxylic acid (TCA) cycle and oxidative phosphorylation processes. These functions highlight its role in maintaining energy efficiency and reducing reactive oxidative species.\u003cbr\u003e\nPathways\u003cbr\u003e\nSIRT3 participates in vital metabolic pathways such as the TCA cycle and the urea cycle. It interacts with other proteins like MnSOD and IDH2 to enhance mitochondrial function and overall cellular metabolism. This helps control the balance between energy production and consumption integrating signals from the AMPK and NAD+-dependent pathways to coordinate responses to changes in energy availability.\u003cbr\u003e\nSIRT3 has implications in metabolic syndrome and cancer. Reduced SIRT3 activity is associated with increased susceptibility to metabolic disturbances like obesity and type 2 diabetes. Its deficiency affects the regulation of ROS and metabolic adaptation linking it to tumorigenesis and cancer progression. As it connects with proteins like HIF-1α in hypoxic conditions SIRT3 plays a role in cellular adaptation to stress influencing disease progression.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843998765225,"sku":"ab97951","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab97951","provider":"Iright","version":"1.0","type":"link"}
