Putative histone deacetylase 2

Gene

hda-2

Organism
Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

Probably 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).By similarity

Catalytic activityi

Hydrolysis of an N(6)-acetyl-lysine residue of a histone to yield a deacetylated histone.
