Recombinant proteins for sirtuin 4 are available from various sources. In humans, this protein has a Uniprot ID of Q9Y6E7 and has an annotated function: 'Acts as NAD-dependent protein lipoamidase, ADP-ribosyl transferase and deacetylase.' This protein is 314 amino acids in length and 35.2 kilodaltons in mass. It has been designated a subcellular localization as: mitochondrial. This protein is encoded by the gene SIRT4. Other names also exist, such as: NAD-dependent protein lipoamidase sirtuin-4, mitochondrial, NAD-dependent ADP-ribosyltransferase sirtuin-4, NAD-dependent protein deacetylase sirtuin-4, SIR2-like protein 4, regulatory protein SIR2 homolog 4, sir2-like 4, sirtuin type 4. This protein is conserved in other species, including: mouse, rat.
