Recombinant proteins for sirtuin 2 are available from various sources. In humans, this protein has a Uniprot ID of Q8IXJ6 and has an annotated function: 'NAD-dependent protein deacetylase, which deacetylates internal lysines on histone and alpha-tubulin as well as many other proteins such as key transcription factors.' This protein is 389 amino acids in length and 43.2 kilodaltons in mass. It has been designated a subcellular localization as: cytoplasmic, nuclear. This protein is encoded by the gene SIRT2. Other names also exist, such as: NAD-dependent protein deacetylase sirtuin-2, NAD-dependent deacetylase sirtuin-2, SIR2-like protein 2, regulatory protein SIR2 homolog 2, silent information regulator 2, sir2-related protein type 2, sirtuin type 2. As many as 5 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
