| 使用方法 | Recombinant JMJD2B / KDM4B protein is suitable for use in the study of enzyme kinetics, inhibitor screening, and selectivity profiling. Specific Activity: H3K9me3 and H3K36me3 demethylase. Histone Demethylase Assay Conditions: 3.3 μM H3K9me3 (aa 1-21) peptide was incubated with different concentrations of recombinant JMJD2B / KDM4B protein in reaction buffer containing 50 mM HEPES pH 7.5, 0.02% Triton X100, 100 μM 2OG, 100 μM Ascorbate, 50 μM (NH4)2Fe(SO4)2·6H2O, 1 mM TCEP for 1 hours at room temperature. HTRF and MALDI-TOF was used for detection. |
| 供应商 | Active Motif |
| 背景 | JMJD2B / KDM4B (JmjC domain-containing histone demethylation protein 3B, Jumonji domain-containing protein 2B, JHDM3B) is a histone demethylase that has been shown to demethylate trimethylated lysine 9 (K9me3) and lysine 36 (K36me3) residues of histone H3, converting these trimethylated histone residues to dimethylated or monomethylated form. KDM4B has no activity for monomethylated H3K9 and H3K36. JMJD2B / KDM4B is physically associated with the MLL2 methyltransferase complex where it serves as a co-factor for ERα-mediated transcriptional activation. |

Recombinant JMJD2B / KDM4B protein gel. JMJD2B / KDM4B protein was run on an 8% SDS-PAGE gel and stained with Coomassie blue. | |
Recombinant JMJD2B / KDM4B protein HTRF activity assay. 3.3 μM H3K9me3 peptide was incubated with JMJD2B / KDM4B in reaction buffer for 1 hours at room temperature. JMJD2B / KDM4B enzyme was used in a HTRF assay to determine enzyme linearity. Demethylated peptide (H3K9me2) was measured using H3K9me2-specific antibody. |
