Lysine-specific demethylase 7A (KDM7A)

Histone demethylase needed 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 doesn't have any demethylase activity toward H3K9me2, while it has high activity toward H3K27me2. Demethylates H3K9me2 in absence of H3K4me3.
