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

JMJD6 is a Jumonji C domain-containing hydroxylase. JMJD6 binds alpha-ketoglutarate and iron and has been characterized as either a histone arginine demethylase or U2AF65 lysyl hydroxylase. Here, we describe the structures of JMJD6 with and without alpha-ketoglutarate, which revealed a novel substrate binding groove and two positively charged surfaces. The structures also contain a stack of aromatic residues located near the active center. The side chain of one residue within this stack assumed different conformations in the two structures. Interestingly, JMJD6 bound efficiently to single-stranded RNA, but not to single-stranded DNA, double-stranded RNA, or double-stranded DNA. These structural features and truncation analysis of JMJD6 suggest that JMJD6 may bind and modify single-stand RNA rather than the previously reported peptide substrates.
