Protein

Probable lysine-specific demethylase 4B

Gene

Kdm4B

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

Probable histone demethylase that specifically demethylates 'Lys-9' and 'Lys-36' residues of histone H3, thereby playing a central role in histone code. Demethylation of Lys residue generates formaldehyde and succinate (By similarity).By similarity

Cofactori

Fe2+By similarityNote: Binds 1 Fe2+ ion per subunit.By similarity
