Protein attributes

Sequence length	1704 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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 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.
Subcellular location	Nucleus By similarity.
Sequence similarities	Belongs to the histone deacetylase family. Type 2 subfamily.
