characterization of a new chemical tool, UNC0965. UNC0965 is a biotinylated version of our previously reported G9a chemical probe, UNC0638. Importantly, UNC0965 maintains high in vitro potency and is cell penetrant. The biotinylated tag of UNC0965 enables “chemiprecipitation” of G9a from whole cell lysates. Further, the cell penetrance of UNC0965 allowed us to explore the localization of G9a on chromatin both
在这里,我们报告了一种新化学工具 UNC0965 的设计、合成和生化表征。UNC0965 是我们之前报道的 G9a 化学探针 UNC0638 的生物素化版本。重要的是,UNC0965 保持高体外效力并且是细胞渗透性的。UNC0965 的生物素化标签能够从全细胞裂解物中“化学沉淀”G9a。此外,UNC0965 的细胞外显率使我们能够通过基于化学抑制剂的染色质免疫沉淀(chem-ChIP)在体外和体内探索 G9a 在染色质上的定位。
