Histone demethylase that specifically demethylates 'Lys-9' of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-4', H3 'Lys-27', H3 'Lys-36' nor H4 'Lys-20'. Demethylates both di- and trimethylated H3 'Lys-9' residue, while it has no activity on monomethylated residues. Demethylation of Lys residue generates formaldehyde and succinate.
Ubiquitinated via 'Lys-63'-linked ubiquitin chains. Deubiquitinated by USP14 with the help of TRIM14 leading to stabilization.
Belongs to the JHDM3 histone demethylase family.
