General annotation (Comments)

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 By similarity.
Catalytic activity	Hydrolysis of an N(6)-acetyl-lysine residue of a histone to yield a deacetylated histone.
Subunit structure	Homodimer. Ref.3
Subcellular location	Nucleus By similarity.
Miscellaneous	Present with 4420 molecules/cell in log phase SD medium. Ref.4
Sequence similarities	Belongs to the histone deacetylase family. Type 1 subfamily.
