Description_x000D_ General description_x000D_ Sirtuin 3 (Sirt3) is an NAD-dependent deacetylase localized to the mitochondrial matrix. SIRT3 encodes a 44 kDa full length form and a N-terminal 142 amino acids truncated form. It is mapped to human chromosome 11p15.5._x000D_ Immunogen_x000D_ synthetic peptide corresponding to amino acids 384-399 of human SIRT3, conjugated to KLH via an N-terminal cysteine residue._x000D_ Application_x000D_ Anti-Sirt3 antibody produced in rabbit has been used in western blotting._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Sirtuin 3 (Sirt3) is mainly a nuclear protein that transfers to the mitochondria during cellular stress. In humans, Sirt3 deacetylates and activates the mitochondrial enzyme acetyl-CoA synthetase 1 (AceCS2). Sirt3 is implicated in regulating mitochondrial function and thermogenesis in brown adipocytes. Its levels have been shown to correlate with extended life span. Increased levels of Sirt3 were associated with node positive breast cancer.
