[https://www.uniprot.org/uniprot/SIR2_HUMAN SIR2_HUMAN] NAD-dependent protein deacetylase, which deacetylates internal lysines on histone and non-histone proteins. Deacetylates 'Lys-40' of alpha-tubulin. Involved in the control of mitotic exit in the cell cycle, probably via its role in the regulation of cytoskeleton. Deacetylates PCK1, opposing proteasomal degradation. Deacetylates 'Lys-310' of RELA.<ref>PMID:12620231</ref> <ref>PMID:12697818</ref> <ref>PMID:21081649</ref> <ref>PMID:21726808</ref>

== Publication Abstract from PubMed ==
Sir2 is an NAD-dependent histone deacetylase that mediates transcriptional silencing at mating-type loci, telomeres and ribosomal gene clusters, and has a critical role in the determination of life span in yeast and Caenorhabditis elegans. The 1.7 A crystal structure of the 323 amino acid catalytic core of human SIRT2, a homolog of yeast Sir2, reveals an NAD-binding domain, which is a variant of the Rossmann fold, and a smaller domain composed of a helical module and a zinc-binding module. A conserved large groove at the interface of the two domains is the likely site of catalysis based on mutagenesis. Intersecting this large groove, there is a pocket formed by the helical module. The pocket is lined with hydrophobic residues conserved within each of the five Sir2 classes, suggesting that it is a class-specific protein-binding site.
