General annotation (Comments)
| Function | Histone lysine demethylase with selectivity for the di- and monomethyl states that plays a key role cell cycle progression, rDNA transcription and brain development. Demethylates mono- and dimethylated histone H3 'Lys-9' residue (H3K9Me1 and H3K9Me2), dimethylated H3 'Lys-27' (H3K27Me2) and monomethylated histone H4 'Lys-20' residue (H4K20Me1). Acts as a transcription activator as H3K9Me1, H3K9Me2, H3K27Me2 and H4K20Me1 are epigenetic repressive marks. Involved in cell cycle progression by being required to control G1-S transition. Acts as a coactivator of rDNA transcription, by activating polymerase I (pol I) mediated transcription of rRNA genes. Required for brain development, probably by regulating expression of neuron-specific genes. Has activity toward H4K20Me1 only when nucleosome is used as a substrate and when not histone octamer is used as substrate. May also have weak activity toward dimethylated H3 'Lys-36' (H3K36Me2), however, the relevance of this result remains unsure in vivo. Specifically binds trimethylated 'Lys-4' of histone H3 (H3K4me3), affecting histone demethylase specificity: has weak activity toward H3K9Me2 in absence of H3K4me3, while it has high activity toward H3K9me2 when binding H3K4me3 By similarity. |
| Catalytic activity | Protein N6,N(6)-dimethyl-L-lysine + 2-oxoglutarate + O2 = protein N(6)-methyl-L-lysine + succinate + formaldehyde + CO2. Protein N(6)-methyl-L-lysine + 2-oxoglutarate + O2 = protein L-lysine + succinate + formaldehyde + CO2. |
| Cofactor | Binds 1 Fe2+ ion per subunit By similarity. |
| Subunit structure | Interacts with POLR1B, UBTF, SETD1A, HCFC1, E2F1 and ZNF711 By similarity. |
| Subcellular location | Nucleus By similarity. Nucleus › nucleolus By similarity. Note: Recruited to H3K4me3 sites on chromatin during interphase. Dissociates from chromatin when cells enter mitosis By similarity. |
| Domain | The PHD-type zinc finger mediates the binding to H3K4me3. Binding to H3K4me3 promotes its access to H3K9me2 By similarity. The linker region is a critical determinant of demethylase specificity. It enables the active site of JmjC to reach the target H3K9me2 when the PHD-type zinc finger binds to H3K4me3 By similarity. |
| Post-translational modification | Phosphorylation at Ser-33 and Ser-84 are required for dissociation from chromatin and accumulation of H4K20Me1 levels during prophase By similarity. |
| Sequence similarities | Belongs to the JHDM1 histone demethylase family. JHDM1D subfamily. Contains 1 JmjC domain. Contains 1 PHD-type zinc finger. |
| Sequence caution | The sequence CAM17163.1 differs from that shown. Reason: Erroneous gene model prediction. |
