一般說明
Sirtuin 2 (SIRT2) is a cytoplasmic protein and is part of the sirtuin family of proteins. Sirtuin family contains a sirtuin core domain and isgrouped into four classes with SIRT2 being a member of class I. SIRT2 colocalizes with microtubules. The gene encoding this protein is localized on human chromosome 19q13.2.
With Sigma′s Sirtuin Inhibitor Screening Kit, Sirtuin deacetylates the Substrate, and then a Developer cleaves the deacetylated substrate to release a fluorescent group, the latter of which can be detected at Ex/Em = 395/541 nm. In the presence of a SIRT inhibitor, the deacetylation will be impeded, preventing substrate cleavage and release of the fluorescent group. The kit provides a rapid, simple, sensitive, and reliable test, which is suitable for both low and high-throughput screening of SIRT2 inhibitors. A positive control inhibitor, Nicotinamide, is included to compare with the efficacy of the test inhibitors.

應用
Sirtuin 2 (SIRT2) inhibitor screening assay kit has been used for acetyl peptide deacetylase assay.
生化／生理作用
Sirtuin 2 (SIRT2) maintains the integrity of the genome. Inhibition of SIRT2 can lead to neuroprotection in cellular and invertebrate models of Huntington′s disease. Huntington′s disease is characterized by increased sterol synthesis in neuronal cells and this process is reversed by SIRT2 inhibition. SIRT2 can deacetylate lys40 of α-tubulin both in vitro and in vivo. Knockdown of SIRT2 by small interfering RNA (siRNA) leads to tubulin hyperacetylation.
