Subcellular location
- Subcellular Location:
- Nucleus. Cytoplasm. Note=Excluded from the nucleoli. Found in the cytoplasm of cells showing smooth muscle differentiation.
Function
- Function:
- Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Also involved in the deacetylation of cohesin complex protein SMC3 regulating release of cohesin complexes from chromatin. May play a role in smooth muscle cell contractility.
- Catalytic Activity:
- Hydrolysis of an N(6)-acetyl-lysine residue of a histone to yield a deacetylated histone.
- Cofactor:
- COFACTOR: Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240; ; Note=Binds 1 divalent metal cation per subunit.;
- Enzyme Regulation:
- ENZYME REGULATION: Its activity is inhibited by trichostatin A (TSA), suberoylanilide hydroxamic acid (SAHA), 3-(1-methyl-4-phenylacetyl-1H-2-pyrrolyl)-N-hydroxy-2-propenamide (APHA), 4-dimethylamino-N-(6-hydroxycarbamoyethyl)benzamide-N-hydroxy-7-(4-dimethylaminobenzoyl)aminoheptanamide (MS-344), 5-(4-methyl-benzoylamino)-biphenyl-3,4'-dicarboxylic acid 3-dimethylamide 4'-hydroxyamide (CRA-A) and butyrate.
