FunctionKDM4A_HUMAN Histone demethylase that specifically demethylates 'Lys-9' and 'Lys-36' residues of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-4', H3 'Lys-27' nor H4 'Lys-20'. Demethylates trimethylated H3 'Lys-9' and H3 'Lys-36' residue, while it has no activity on mono- and dimethylated residues. Demethylation of Lys residue generates formaldehyde and succinate. Participates in transcriptional repression of ASCL2 and E2F-responsive promoters via the recruitment of histone deacetylases and NCOR1, respectively.[1] [2] [3] Isoform 2: Crucial for muscle differentiation, promotes transcriptional activation of the Myog gene by directing the removal of repressive chromatin marks at its promoter. Lacks the N-terminal demethylase domain.[4] [5] [6] Publication Abstract from PubMedJIB-04, a specific inhibitor of the O2-activating, Fe-dependent histone lysine demethylases, is revealed to disrupt the binding of O2 in KDM4A/JMJD2A through a continuous O2-consumption assay, X-ray crystal structure data, and molecular docking. The small molecule JIB-04 disrupts O2 binding in the Fe-dependent histone demethylase KDM4A/JMJD2A.,Cascella B, Lee SG, Singh S, Jez JM, Mirica LM Chem Commun (Camb). 2017 Feb 9;53(13):2174-2177. doi: 10.1039/c6cc09882g.
