Binding
KDM5 Enzyme Assay: Full length KDM5A enzyme was expressed and purified inhouse. Biotin-H3K4me3 peptide was purchased from New England Biolabs. HTRF reagents (containing Eu-labeled H3K4me1-2 antibody, and streptavidin-XL665) were purchased from Cis-Bio International. Plates were read on an Envision multi-label plate reader (Perkin Elmer).The HTRF assay mixture contained 2 nM full length KDM5A enzyme, 100 nM H3K4Me3 peptide substrate, 1 uM 2-OG, 100 uM Fe2+, 500 uM ascorbate. 50 mM HEPES pH 7.0 buffer, 0.01% Triton-X 100, 2 mM DTT, 0.25% DMSO at a final volume of 10 uL.The enzyme reaction was carried out at room temperature in black Proxiplate 384-Plus plate (Corning. Costar) within 30 minutes, in the presence of varying concentration of a test compound. At the end of enzyme reaction, 5 uL of 1 mM EDTA were added to quench the reaction and then the detection reagents (5 uL) were added to give final concentrations of 0.5 nM Eu-labeled H3K4me1-2 antibody, and 50 nM streptavidin-XL665. The plates were incubated at room temperature for 60 minutes and then read in the Envision plate reader. The readouts were transformed into % inhibition, and IC50 value of a test compounds was generated by using four parameters curve fitting (Model 205 in XLFIT5, iDBS).
