1/500. Detects a band of approximately 107 kDa (predicted molecular weight: 107 kDa).
功能Histone demethylase required for brain development. Specifically demethylates dimethylated 'Lys-9' and 'Lys-27' (H3K9me2 and H3K27me2, respectively) of histone H3 and monomethylated histone H4 'Lys-20' residue (H4K20Me1), thereby playing a central role in histone code. Specifically binds trimethylated 'Lys-4' of histone H3 (H3K4me3), affecting histone demethylase specificity: in presence of H3K4me3, it has no demethylase activity toward H3K9me2, while it has high activity toward H3K27me2. Demethylates H3K9me2 in absence of H3K4me3. Has activity toward H4K20Me1 only when nucleosome is used as a substrate and when not histone octamer is used as substrate.
序列相似性Belongs to the JHDM1 histone demethylase family. JHDM1D subfamily. Contains 1 JmjC domain. Contains 1 PHD-type zinc finger.
结构域The PHD-type zinc finger mediates the binding to H3K4me3. Binding to H3K4me3 prevents its access to H3K9me2. The linker region is a critical determinant of demethylase specificity. It prevents the active site of JmjC to reach the target H3K9me2 when the PHD-type zinc finger binds to H3K4me3, while it favors selectivity toward H3K27me2.
