The histone deacetylase (HDAC) family of enzymes are involved in the post-translational modification of histones by removal of acetyl groups from lysine residues. Removal of the acetyl groups facilitates tighter packing of chromatin (heterochromatin formation) leading to transcriptional repression. In humans, the 18 members of the HDAC family have been classified in to five subfamilies based on phylogenetic comparison with yeast homologues (see our HDACs Concise family page for more details).

A recent review and analysis of the P. falciparum genome confirmed and classified the five known HDACs for this species of the parasite and identified a novel putative HDAC [4]:
Class I contains PfHDAC1
Class II contains PfHDA1 and PfHDA2
Class III contains the sirtuin-like PfSir2A and PfSir2B
PfCHD1 is a novel unclassified HDAC

HDACs have been identified as attractive molecular targets in the search for novel mechanisms to treat cancer and several small molecule HDAC inhibitors are already approved for clinical use. HDAC inhibitors have also emerged as potential therapies in a number of other disesases including malaria [1-3].
