Histone deacetylase 9 (HDAC9)

Responsible for the deacetylation of lysine residues on the N-terminal portion 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.

Represses MEF2-dependent transcription. .
