Function

[JMJD6_HUMAN] Dioxygenase that can both act as a histone arginine demethylase and a lysyl-hydroxylase. Acts as a lysyl-hydroxylase that catalyzes 5-hydroxylation on specific lysine residues of target proteins such as U2AF2/U2AF65 and LUC7L2. Acts as a regulator of RNA splicing by mediating 5-hydroxylation of U2AF2/U2AF65, affecting the pre-mRNA splicing activity of U2AF2/U2AF65. In addition to peptidyl-lysine 5-dioxygenase activity, may act as a RNA hydroxylase, as suggested by its ability to bind single strand RNA. Also acts as an arginine demethylase which demethylates histone H3 at 'Arg-2' (H3R2me) and histone H4 at 'Arg-3' (H4R3me), thereby playing a role in histone code. However, histone arginine demethylation may not constitute the primary activity in vivo. Has no histone lysine demethylase activity. Required for differentiation of multiple organs during embryogenesis. Acts as a key regulator of hematopoietic differentiation: required for angiogenic sprouting by regulating the pre-mRNA splicing activity of U2AF2/U2AF65. Seems to be necessary for the regulation of macrophage cytokine responses.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

Lysyl and prolyl hydroxylations are well-known post-translational modifications to animal and plant proteins with extracellular roles. More recent work has indicated that the hydroxylation of intracellular animal proteins may be common. JMJD6 catalyses the iron- and 2-oxoglutarate-dependent hydroxylation of lysyl residues in arginine-serine-rich domains of RNA-splicing-related proteins. We report crystallographic studies on the catalytic domain of JMJD6 in complex with Ni(II) substituting for Fe(II). Together with mutational studies, the structural data suggest how JMJD6 binds its lysyl residues such that it can catalyse C-5 hydroxylation rather than N(varepsilon)-demethylation, as for analogous enzymes.
