Sirtuin-2 is a NAD-dependent protein deacetylase, which deacetylates the 'Lys-40' of a-tubulin. It is involved in the control of mitotic exit in the cell cycle. Furthermore, a variety of age-associated diseases such as type 2 diabetes, obesity, osteoporosis, and Alzheimer's disease are associated with sirtuins. Selective inhibition of Sirtuin-2 achieves neuroprotection and identifies Sirtuin-2 to be a potential therapeutic avenue in Huntington's and Parkinson's disease.
