Purity > 90% as determined by SDS-PAGE. MW: 34.3kDa. Full Length: 1-306aa. N-terminal 6xHis-tagged. Arabidopsis thaliana (Mouse-ear cress). Probably mediates 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.
