General annotation (Comments)

Function	NAD-dependent protein deacetylase, which deacetylates internal lysines on histone and non-histone proteins. Deacetylates '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. Deacetylates PCK1, opposing proteasomal degradation. Deacetylates 'Lys-310' of RELA. Ref.12 Ref.13 Ref.19 Ref.20
Catalytic activity	NAD+ + an acetylprotein = nicotinamide + O-acetyl-ADP-ribose + a protein. Ref.11
Cofactor	Binds 1 zinc ion per subunit.
Enzyme regulation	Inhibited by Sirtinol, A3 and M15 small molecules. Inhibited by nicotinamide.
Subunit structure	Interacts with HDAC6, suggesting that these proteins belong to a large complex that deacetylate the cytoskeleton. Ref.12
Subcellular location	Cytoplasm › cytoskeleton. Note: Colocalizes with microtubules. Ref.2 Ref.12 Ref.15
Tissue specificity	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. Ref.1 Ref.2 Ref.14
Developmental stage	Peaks during mitosis. After mitosis, it is probably degraded by the 26S proteasome. Ref.13
Post-translational modification	Phosphorylated at the G2/M transition of the cell cycle. Ref.13
Miscellaneous	Has some ability to deacetylate histones in vitro, but seeing its subcellular location, this is unlikely in vivo.
Sequence similarities	Belongs to the sirtuin family. Class I subfamily. Contains 1 deacetylase sirtuin-type domain.
Sequence caution	The sequence AAD45971.1 differs from that shown. Reason: Erroneous initiation. The sequence AAF67015.1 differs from that shown. Reason: Frameshift at several positions.
