Full length recombinant JMJD2C / KDM4C protein was expressed in Sf9 cells and is supplied in 25 mM HEPES pH 7.5, 300 mM NaCl, 5% Glycerol, 0.04% Triton X-100, 0.2 mM TCEP. Please refer to product insert upon arrival for lot-specific concentration.
KDM4C (lysine (K)-specific demethylase 4C), also known as JMJD2C (Jumonji Domain Containing 2C) is a nuclear protein that functions as a histone demethylase that preferentially demethylates di- and trimethylated lysine 9 (K9me3) and lysine 36 (K36me3) residues of histone H3, converting these trimethylated histone residues to mono- or dimethylated form. JMJD2C / KDM4C has no activity for monomethylated H3K9 and H3K36. Chromosomal aberrations and overexpression of KDM4C are associated with esophageal squamous cell carcinoma. KDM4C regulates colonosphere formation in colorectal cancers by mediating the crosstalk between Wnt and Notch signaling pathways.
Recombinant JMJD2C / KDM4C is suitable for use in the study of enzyme kinetics, inhibitor screening, and selectivity profiling
Histone Demethylase Assay Conditions: 1 µM H3K9me3 peptide was incubated with different concentrations of JMJD2C / KDM4C protein in 10 µl reaction system containing 50 mM HEPES-NaOH pH 7.5, 1 mM TCEP, 50 µM 2-OG, 50 µM Ascorbate, 25 µM (NH4)2Fe(SO4)2·6H2O for 1 hour, then 10 µl H3K9me2 antibody and SA-XL665 mixture (1:100 dilution in HTRF Detection Buffer) was added to each reaction system and incubated for 30 min. All the operations and reactions were performed at room temperature. HTRF assay was used for detection.
