Histone methylations are important chromatin marks that regulate gene expression, genomic stability, DNA repair, and genomic imprinting. Histone demethylases are the most recent family of histone-modifying enzymes discovered. Here, we report the characterization of a small-molecule inhibitor of Jumonji C domain-containing histone demethylases. The inhibitor derives from a structure-based design and
组蛋白甲基化是调节基因表达、基因组稳定性、DNA 修复和基因组印记的重要染色质标记。组蛋白去甲基化酶是最新发现的组蛋白修饰酶家族。在这里,我们报告了含有 Jumonji C 域的组蛋白去甲基化酶的小分子抑制剂的表征。该抑制剂源自基于结构的设计,优先抑制三甲基赖氨酸脱甲基酶亚家族。其甲基酯前药methylstat 可选择性抑制细胞中含有Jumonji C 结构域的组蛋白去甲基化酶,可能是染色质及其在表观遗传学中作用的有用小分子探针。
