The SIRT2 gene encodes an enzyme that is responsible for the NAD-dependent deacetylation of histones and alpha-tubulin. The enzyme is thus involved in several cellular processes such as autophagy, lipid and protein catabolism, transcription, chromatin and gene silencing, the meiotic cell cycle and cell proliferation. It is responsible for the cellular response to oxidative stress, hypoxia, caloric restriction, epinephrine stimulus, hepatocyte growth factor stimulus and molecules of bacterial origin. SIRT2 also plays a role in striated muscle tissue development, myelination in the peripheral nervous system during postnatal development and remyelination post-injury.
