the kdmA mutant shows a significant increase in H3K36me3 during primary metabolism at the aflR and ipnA locus and some slightly higher levels at the aptA genes, the mutant has reduced levels of sterigmatocystin compared to wild-type, mutant phenotype, overview. Deletion of kdmA in Aspergillus nidulans produces both positive and negative changes in transcriptional readouts and the number of affected genes is different under different conditions. KdmA deletion alters expression pattern of secondary metabolism cluster genes in secondary metabolism phase, analysis of the heat map for mean expression of previously annotated secondary metabolism clusters. Deletion of kdmA causes light lethality and sensitivity to oxidative stress during vegetative growth

construction of a P-element insertion mutant of dKDMA4, the mutant is homozygous viable, the P element insertion elevates the bulk level of histone H3K36me3 in mutant embryos. Overexpression of dKDM4A seems to only lead to demethylation of histone H3K36, since the level of histone H3K9me3 and H3K4me2 remains unchanged

enzyme engineering and swapping of the C-terminus region containing the distal Tudor domain between isozymes KDM4C and KDM4A, construction of diverse chimeric enzyme mutants, overview. Chimera5, which encodes the first 934 amino acids of KDM4C fused with the last 129 amino acid containing the distal Tudor domain of KDM4A, is excluded from mitotic chromatin. On the other hand, chimera6 that encodes the first 954 amino acids of KDM4A fused to 101 amino acids of KDM4C, which includes its distal Tudor domain, remains excluded from chromatin. The C-terminus of KDM4C containing the distal Tudor domain is essential but not sufficient for its mitotic chromatin localization

generation of conditional Jmjd2a/Kdm4a, Jmjd2b/Kdm4b and Jmjd2c/Kdm4c/Gasc1 single, double and triple knockout mouse embryonic stem cells (ESCs). While individual Jmjd2 family members are dispensable for ESC maintenance and embryogenesis, combined deficiency for specifically Jmjd2a and Jmjd2c leads to early embryonic lethality and impaired ESC self-renewal, with spontaneous differentiation towards primitive endoderm under permissive culture conditions. Increased H3K9me3 levels in knockout ESCs compromise the expression of several Jmjd2a/c targets, including genes that are important for ESC self-renewal. Thus, continual removal of H3K9 promoter methylation by Jmjd2 demethylases represents a novel mechanism ensuring transcriptional competence and stability of the pluripotent cell identity.
