Methylation of lysine residues in core histones plays a critical role in regulating gene expression.1 Jumonji domain containing 2D (JMJD2D) catalyzes the demethylation of di- and tri-methylated forms of histone H3 at lysine residue 9 (me 2/3), leading to transcriptional repression and activation, respectively.2 Like other JmjC protein hydroxylase family members, JMJD2D is an α-ketoglutarate-dependent Fe (II) oxygenase.3 Purification of Fe-dependent JmjC family members by IMAC can result in displacement of the catalytic iron and decreased activity, therefore this Strep-tagged protein is purified by affinity chromatography using Strep-Tactin coated resin.4 Because of their implication in cancer cell growth, jumonji C domain-containing histone demethylase inhibitors may have the capacity to be anticancer agents.1WARNING This product is not for human or veterinary use.
