General annotation (Comments)
| Function | Histone demethylase that specifically demethylates 'Lys-36' of histone H3, thereby playing a central role in histone code. Preferentially demethylates dimethylated H3 'Lys-36' residue while it has weak or no activity for mono- and tri-methylated H3 'Lys-36'. May also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. Required to maintain the heterochromatic state. Associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at the centromere. Required to sustain centromeric integrity and genomic stability, particularly during mitosis. Ref.9 |
| Catalytic activity | Protein N6,N(6)-dimethyl-L-lysine + 2-oxoglutarate + O2 = protein N(6)-methyl-L-lysine + succinate + formaldehyde + CO2. Ref.9 Protein N(6)-methyl-L-lysine + 2-oxoglutarate + O2 = protein L-lysine + succinate + formaldehyde + CO2. Ref.9 |
| Cofactor | Binds 1 Fe2+ ion per subunit. Ref.9 |
| Subunit structure | Part of a SCF (SKP1-cullin-F-box) protein ligase complex By similarity. Interacts with CBX5/HP1A; the interaction promotes CBX5 localization to chromatin. |
| Subcellular location | Nucleus › nucleoplasm. Note: Punctate expression throughout the nucleoplasm and enriched in the perinucleolar region. |
| Tissue specificity | Widely expressed, with highest levels in brain, testis and ovary, followed by lung. Ref.2 |
| Domain | The JmjC domain mediates demethylation activity and is required for satellite silencing. |
| Post-translational modification | Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.8 Ref.10 Ref.11 Ref.13 Ref.14 |
| Sequence similarities | Belongs to the JHDM1 histone demethylase family. Contains 1 CXXC-type zinc finger. Contains 1 F-box domain. Contains 1 JmjC domain. Contains 3 LRR (leucine-rich) repeats. Contains 1 PHD-type zinc finger. |
| Sequence caution | The sequence BAB15795.1 differs from that shown. Reason: Frameshift at position 410. |
