CC -!- FUNCTION: Dioxygenase that can both act as a arginine demethylase and a
CC lysyl-hydroxylase. Acts as a lysyl-hydroxylase that catalyzes 5-
CC hydroxylation on specific lysine residues of target proteins such as
CC U2AF2/U2AF65 and LUC7L2. Regulates RNA splicing by mediating 5-
CC hydroxylation of U2AF2/U2AF65, affecting the pre-mRNA splicing activity
CC of U2AF2/U2AF65. Hydroxylates its own N-terminus, which is required for
CC homooligomerization. In addition to peptidyl-lysine 5-dioxygenase
CC activity, may act as an RNA hydroxylase, as suggested by its ability to
CC bind single strand RNA. Also acts as an arginine demethylase which
CC preferentially demethylates asymmetric dimethylation. Demethylates
CC histone H3 at 'Arg-2' (H3R2me) and histone H4 at 'Arg-3' (H4R3me),
CC including mono-, symmetric di- and asymmetric dimethylated forms,
CC thereby playing a role in histone code. However, histone arginine
CC demethylation may not constitute the primary activity in vivo. In
CC collaboration with BRD4, interacts with the positive transcription
CC elongation factor b (P-TEFb) complex in its active form to regulate
CC polymerase II promoter-proximal pause release for transcriptional
CC activation of a large cohort of genes. On distal enhancers, so called
CC anti-pause enhancers, demethylates both histone H4R3me2 and the methyl
CC cap of 7SKsnRNA leading to the dismissal of the 7SKsnRNA:HEXIM1
CC inhibitor complex. After removal of repressive marks, the complex
CC BRD4:JMJD6 attract and retain the P-TEFb complex on chromatin, leading
CC to its activation, promoter-proximal polymerase II pause release, and
CC transcriptional activation. Demethylates other arginine methylated-
CC proteins such as ESR1. Has no histone lysine demethylase activity (By
CC similarity). Required for differentiation of multiple organs during
CC embryogenesis. Acts as a key regulator of hematopoietic
CC differentiation: required for angiogenic sprouting by regulating the
CC pre-mRNA splicing activity of U2AF2/U2AF65 (By similarity). Seems to be
CC necessary for the regulation of macrophage cytokine responses (By
CC similarity). {ECO:0000250|UniProtKB:Q6NYC1,
