  • FunctionHistone demethylase that specifically demethylates 'Lys-9' of histone H3, thereby playing a role in histone code. Does not demethylate histone H3 'Lys-4', H3 'Lys-27', H3 'Lys-36' nor H4 'Lys-20'. Only able to demethylate trimethylated H3 'Lys-9', with a weaker activity than KDM4A, KDM4C and KDM4D. Demethylation of Lys residue generates formaldehyde and succinate.
  • Sequence similaritiesBelongs to the JHDM3 histone demethylase family.
    Contains 1 JmjC domain.
    Contains 1 JmjN domain.
    Contains 2 PHD-type zinc fingers.
    Contains 2 Tudor domains.
  • DomainThe 2 Tudor domains recognize and bind methylated histones. Double Tudor domain has an interdigitated structure and the unusual fold is required for its ability to bind methylated histone tails.
  • Cellular localizationNucleus.
