General Information

1.14.11.27 evolution two families of lysine demethylases (KDM) are identified. The KDM4 family consists of four members: KDM4A, KDM4B, KDM4C and KDM4D Homo sapiens

1.14.11.27 malfunction dysregulated expression of KDM4A-D family promotes chromosomal instabilities. Depletion or overexpression of KDM4B does not leads to an increase in the frequency of abnormal mitotic cells and has no detectable effect on mitotic chromosome segregation Homo sapiens
1.14.11.27 malfunction dysregulated expression of KDM4A-D family promotes chromosomal instabilities. Depletion or overexpression of KDM4C, but not KDM4B, leads to over 3fold increase in the frequency of abnormal mitotic cells showing either misaligned chromosomes at metaphase, anaphase-telophase lagging chromosomes or anaphase-telophase bridges. Overexpression of a KDM4C demethylase dead mutant has no detectable effect on mitotic chromosome segregation Homo sapiens
1.14.11.27 physiological function the KDM4 isozymes are involved in histone methylation, a reversible and dynamically regulated process. Various types of human cancers exhibit amplification or deletion of KDM4A-D members, which selectively demethylate lysine residues on histone H3, i.e. H3K9 and H3K36, thus implicating their activity in promoting carcinogenesis. Isozyme KDM4A is not associated with chromatin during mitosis, in contrast to isozyme KDM4C Homo sapiens

Various types of human cancers exhibit amplification or deletion of KDM4A-D members, which selectively demethylate lysine residues on histone H3, i.e. H3K9 and H3K36, thus implicating their activity in promoting carcinogenesis. Unlike KDM4A-B, isozyme KDM4C is associated with chromatin during mitosis. This association is accompanied by a decrease in the mitotic levels of H3K9me3. The C-terminal region, containing the Tudor domains of KDM4C, is essential for its association with mitotic chromatin, especially residue R919 on the proximal Tudor domain of KDM4C is critical for its association with chromatin during mitosis. The demethylase activity and the mitotic localization of KDM4C influence the integrity of mitotic chromosome segregation Homo sapiens
1.14.11.66 evolution the human KDM4 family consists of four members, KDM4A-D (also known as JMJD2A-D). These enzymes specifically catalyze the demethylation of H3K9me3/me2, H3K36me2/me3 and H1.4K26me2/me3 in a Fe2+ and 2-oxoglutarate-dependent manner. Besides the catalytic JmjC domain, KDM4 demethylases contain the JmjN domain, which is also required for the demethylase activity. In addition, all KDM4 members, except the shortest KDM4D protein, contain two Plant homeodomain (PHD) and two Tudor domains. Gene KDM4D is Y chromosome-encoded and a truncated enzyme variant compared to KDM4A-C Homo sapiens
