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. Required for proper positioning of nucleosomes at heterochromatic loci and for transcriptional gene silencing (TGS) function of the Snf2/Hdac-containing repressor complex (SHREC). Ref.4
Catalytic activity	Hydrolysis of an N(6)-acetyl-lysine residue of a histone to yield a deacetylated histone.
Subunit structure	Interacts with ccq1, clr1, clr2 and mit1. Ref.4
Subcellular location	Nucleus. Note: Associates with major heterochromatin, centromeres, sub-telomeres, rDNA and the mat locus. Ref.4 Ref.3
Sequence similarities	Belongs to the histone deacetylase family. Type 2 subfamily.
