selectively recognized by bromodomain “reader” modules. Inhibitors of the bromodomain and extra terminal domain (BET) family of bromodomains have shown profound anticancer and anti-inflammatory properties, generating much interest in targeting other bromodomain-containing proteins for disease treatment. Herein, we report the discovery of I-BRD9, the first selective cellular chemical probe for bromodomain-containing
组蛋白赖氨酸残基的乙酰化是对染色质的研究程度最高的翻译后修饰之一,可被溴结构域“阅读器”模块选择性识别。溴结构域和溴结构域的额外末端结构域(BET)家族的抑制剂已显示出深厚的抗癌和抗炎特性,引起了人们对靶向其他含溴结构域的蛋白质进行疾病治疗的浓厚兴趣。在本文中,我们报告了I-BRD9的发现,I-BRD9是含溴结构域的蛋白9(BRD9)的第一个选择性细胞化学探针。I-BRD9是通过基于结构的设计鉴定的,导致对BET家族的选择性超过700倍,对高度同源的含溴结构域的蛋白质7(BRD7)的选择性超过200倍。
