Inhibitors of both the N-methyl lysyl- and arginyl- demethylase activities of the JmjC oxygenases

| description | The Jumonji C (JmjC) family of 2-oxoglutarate (2OG) dependent oxygenases have established roles in the regulation of transcription via the catalysis of demethylation of Nε-methylated lysine residues in histone tails, especially the N-terminal tail of histone H3. Most human JmjC KDMs are complex enzymes, with ‘reader domains’ in addition to their catalytic domains. Recent biochemical evidence has shown that some, but not all, JmjC KDMs also have Nω-methyl arginyl demethylase (RDM) activity. JmjC KDM activity has been linked to multiple cancers and some JmjC proteins are therapeutic targets. It is therefore important to test not only whether compounds in development inhibit the KDM activity of targeted JmjC demethylases, but also whether they inhibit other activities of these proteins. Here we report biochemical studies on the potential dual inhibition of JmjC KDM and RDM activities using a model JmjC demethylase, KDM4E (JMJD2E). The results reveal that all of tested compounds inhibit both the KDM and RDM activities, raising questions about the in vivo effects of the inhibitors. |
