SIRT2

SIRT2

A gene on chromosome 19q13 that encodes a widely expressed NAD-dependent enzyme that deacetylates Lys-40 of alpha-tubulin and is involved in controlling mitotic exit in the cell cycle, possibly by cytoskeletal regulation.

Seven sirtuins exist with specific locations in the cell: Sirt1,6 and 7 are in the nucleus, Sirt2 in the cytosol, and Sirts3, 4, and 5 in the mitochondria (33).
Now, a team of Japanese researchers has identified a sirtuin enzyme (Sirt2) as a key player in regulating hepatic glucokinase through modifying GKRP, suggesting that this mechanism offers a potential therapeutic target for type 2 diabetes.

CDK9's role in promoting genome integrity is regulated at least in part through deacetylation by the SIRT2 sirtuin deacetylase and breast tumor suppressor protein, which promotes its kinase activity [11] and in turn phosphorylates UBE2A and directs H2Bub1 and PCNA ubiquitinylation [12].
