Jumonji Domain Containing 6, also known as JMJD6 performs as a lysyl-hydroxylase which catalyzes 5-hydroxylation on specific lysine residues of target proteins for instance U2AF2/U2AF65 and LUC7L2, as a regulator of RNA splicing by mediating 5-hydroxylation of U2AF2/U2AF65, affecting the pre-mRNA splicing activity of U2AF2/U2AF65. Additionally to peptidyl-lysine 5-dioxygenase activity, JMJD6 performs as an RNA hydroxylase, as proposed by its ability to bind single strand RNA. Furthermore, it acts as an arginine demethylase which demethylates histone H3 at 'Arg-2' (H3R2me) as well as histone H4 at 'Arg-3' (H4R3me), thus taking a part in histone code.
