additional information | bifunctional KDM4A catalyzes demethylation of tri- and di-methylated forms of both histone H3 lysine 9 (H3K9me3/me2) and lysine 36 (H3K36me3/me2). Enzyme KDM4A preferentially catalyzes demethylation at Lys9 rather than Lys36 under identical conditions. Demethylation of H3K9me3 to H3K9me0 is observed on prolonged incubation of 15-residue H3K9me3 peptides | Homo sapiens | ? | - |

General Information | Comment | Organism |
---|---|---|
evolution | the enzyme belongs to the KDM4/JmjC demethylase histone demethylase family. KDM4F is very similar to KDM4E sharing 94% identity over 369 residues. The selectivity of KDM4 enzymes is determined by multiple interactions within the catalytic domain but outside the active site. Evolutionary analysis of the KDM4 demethylase subfamily | Homo sapiens |
evolution | the enzyme belongs to the KDM4/JmjC demethylase histone demethylase family. The selectivity of KDM4 enzymes is determined by multiple interactions within the catalytic domain but outside the active site. All KDM4 subfamily members have highly conserved residues lining the methylammonium-binding pocket. The exceptions are Ser288A/Ser-289B/Ser290C and Thr289A/Thr290B/Thr291C in KDM4A, B, and C, which are substituted by Ala287D/Ala289E/Ala286F and Ile288D/Ile290E/Ile287F in KDM4D-F, respectively.
