Protein 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. Only has activity toward H4K20Me1 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. / 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. / Fe2+ / 134 µM for histone H3 H3K9Me2 / 8 µM for histone H3 H3K4me3 and H3K9Me2

Involvement in disease

Mental retardation, X-linked, syndromic, Siderius type (MRXSSD) [MIM:300263]: A syndrome characterized by mild to borderline mental retardation with or without cleft lip/cleft palate. . Note: The disease is caused by mutations affecting the gene represented in this entry.

Protein sequence and domain

The PHD-type zinc finger mediates the binding to H3K4me3. Binding to H3K4me3 promotes its access to H3K9me2. / 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. / Belongs to the JHDM1 histone demethylase family. JHDM1D subfamily. / Contains 1 JmjC domain. / Contains 1 PHD-type zinc finger.

Protein post-translational modifications

Phosphorylation at Ser-69 and Ser-120 are required for dissociation from chromatin and accumulation of H4K20Me1 levels during prophase.
