Recombinant proteins for sirtuin 3 are available from various sources. In humans, this protein has a Uniprot ID of Q9NTG7 and has an annotated function: 'NAD-dependent protein deacetylase.' This protein is 399 amino acids in length and 43.6 kilodaltons in mass. It has been designated a subcellular localization as: mitochondrial. This protein is encoded by the gene SIRT3. Other names also exist, such as: NAD-dependent protein deacetylase sirtuin-3, mitochondrial, NAD-dependent deacetylase sirtuin-3, mitochondrial, SIR2-like protein 3, mitochondrial nicotinamide adenine dinucleotide-dependent deacetylase, regulatory protein SIR2 homolog 3, silent mating type information regulation 2, S.cerevisiae, homolog 3, sir2-like 3, sirtuin type 3. As many as 2 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
