Recombinant proteins for sirtuin 7 are available from various sources. In humans, this protein has a Uniprot ID of Q9NRC8 and has an annotated function: 'NAD-dependent protein deacetylase that specifically mediates deacetylation of histone H3 at 'Lys-18' (H3K18Ac).' This protein is 400 amino acids in length and 44.9 kilodaltons in mass. It has been designated a subcellular localization as: cytoplasmic, nuclear. This protein is encoded by the gene SIRT7. Other names also exist, such as: NAD-dependent protein deacetylase sirtuin-7, NAD-dependent deacetylase sirtuin-7, SIR2-like protein 7, regulatory protein SIR2 homolog 7, silent mating type information regulation 2, S.cerevisiae, homolog 7, sir2-related protein type 7, sirtuin type 7. As many as 3 isoforms have been named. This protein is conserved in other species, including: mouse, rat.
