Sirtuin (silent mating type information regulation 2 homolog) 2 (S.cerevisiae)
Sirtuin type 2
NAD-dependent protein deacetylase, which deacetylates the '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.
Widely expressed. Highly expressed in heart, brain and skeletal muscle, while it is weakly expressed in placenta and lung. Down-regulated in many gliomas suggesting that it may act as a tumor suppressor gene in human gliomas possibly through the regulation of microtubule network.
Belongs to the sirtuin family. Contains 1 deacetylase sirtuin-type domain.
Peaks during mitosis. After mitosis, it is probably degraded by the 26S proteasome.
Phosphorylated at the G2/M transition of the cell cycle.
Cytoplasm > cytoskeleton. Colocalizes with microtubules.
