Recombinant part of Arabidopsis thaliana HDT1 Q9FVE6, At3g44750
HDT1 (HD2A) is probably mediating in 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 cell cycle progression
