This is the tudor domain found in histone demethylase Jumonji domain-containing protein 2A (JMJD2A). Structure and function analysis indicate that this domain can recognize equally well two unrelated histone peptides, H3K4me3 and H4K20me3, by means of two very different binding mechanisms [3]. JMJD2 also known as KDM4, is a conserved iron (II)-dependent jumonji-domain demethylase subfamily that is essential during development. Vertebrate KDM4A-C proteins contain a conserved double tudor domain (DTD) [6].	Domain
