General Information | Comment | Organism |
---|---|---|
malfunction | enzyme mutants show 99 misregulated genes in first instar larvae. dKDM4A overexpression results in a global decrease in H3K36me3 levels and male lethality, which might be caused by impaired dosage compensation | Drosophila melanogaster |
additional information | a modest increase in global H3K36me3 levels is compatible with viability, fertility, and the expression of most genes, whereas decreased H3K36me3 levels are detrimental in males | Drosophila melanogaster |
physiological function | identification of dKDM4A-regulated genes, overview. Appropriate expression levels for some dKDM4A-regulated genes rely on the demethylase activity of dKDM4A, whereas others do not. Highly expressed, many demethylase-dependent and independent genes are devoid of H3K36me3 in wild-type as well as in dKDM4A mutant larvae. Some of the most strongly affected genes in dKDM4A mutant animals are not regulated by H3K36 methylation | Drosophila melanogaster |
