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.

== Function ==

[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>
