Does not demethylate histone H3 'Lys-4', H3 'Lys-27', H3 'Lys-36' nor H4 'Lys-20'. Only able to demethylate trimethylated H3 'Lys-9', with a weaker activity than KDM4A, KDM4C and KDM4D. Demethylation of Lys residue generates formaldehyde and succinate. {ECO:0000269|PubMed:16603238, ECO:0000269|PubMed:28262558}. |JmjC| |JmjN| |histone H3-K36 demethylation| |histone demethylase activity (H3-K36 specific)| |histone demethylase activity (H3-K9 specific)| |histone demethylase activity| |histone H3-K9 demethylation| |histone lysine demethylation| |histone demethylation| |protein dealkylation| |protein demethylation| |histone methyltransferase complex| |demethylation| |chromatin remodeling| |histone modification| |covalent chromatin modification| |chromatin organization| |oxidation-reduction process| |chromosome organization| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp16|DABN 2μM R00 exp16]]|-1.72| |[[:results:exp494|Isoniazid 100μM R08 exp494]]|1.72| |[[:results:exp46|HMS-I1 1μM R01 exp46]]|1.8| |[[:results:exp59|UMK57 1μM R01 exp59]]|1.9| No correlation found to any other genes in chemogenomics.
