Inhibitors of Protein Methyltransferases and Demethylases.

ABSTRACT: Post-translational modifications of histones by protein methyltransferases (PMTs) and histone demethylases (KDMs) play an important role in the regulation of gene expression and transcription and are implicated in cancer and many other diseases. Many of these enzymes also target various nonhistone proteins impacting numerous crucial biological pathways. Given their key biological functions and implications in human diseases, there has been a growing interest in assessing these enzymes as potential therapeutic targets. Consequently, discovering and developing inhibitors of these enzymes has become a very active and fast-growing research area over the past decade. In this review, we cover the discovery, characterization, and biological application of inhibitors of PMTs and KDMs with emphasis on key advancements in the field. We also discuss challenges, opportunities, and future directions in this emerging, exciting research field.

Project description:Dynamic histone lysine methylation, regulated by methyltransferases and demethylases, plays fundamental roles in chromatin structure and gene expression in a wide range of eukaryotic organisms. A large number of SET-domain-containing proteins make up the histone lysine methyltransferase (HKMT) family, which catalyses the methylation of different lysine residues with relatively high substrate specificities. Another large family of Jumonji C (JmjC)-domain-containing histone lysine demethylases (JHDMs) reverses histone lysine methylation with both lysine site and methyl-state specificities. Through bioinformatic analysis, at least nine SET-domain-containing genes were found in the malaria parasite Plasmodium falciparum and its sibling species. Phylogenetic analysis separated these putative HKMTs into five subfamilies with different putative substrate specificities. Consistent with the phylogenetic subdivision, methyl marks were found on K4, K9 and K36 of histone H3 and K20 of histone H4 by site-specific methyl-lysine antibodies. In addition, most SET-domain genes and histone methyl-lysine marks displayed dynamic changes during the parasite asexual erythrocytic cycle, suggesting that they constitute an important epigenetic mechanism of gene regulation in malaria parasites. Furthermore, the malaria parasite and other apicomplexan genomes also encode JmjC-domain-containing proteins that may serve as histone lysine demethylases. Whereas prokaryotic expression of putative active domains of four P. falciparum SET proteins did not yield detectable HKMT activity towards recombinant P. falciparum histones, two protein domains expressed in vitro in a eukaryotic system showed HKMT activities towards H3 and H4, respectively. With the discovery of these Plasmodium SET- and JmjC-domain genes in the malaria parasite genomes, future efforts will be directed towards elucidation of their substrate specificities and functions in various cellular processes of the parasites.
