EN219 是一种 E3 泛素连接酶 RNF114 招募剂,特异性结合其本质无序区域的 C8 半胱氨酸,IC50 为 470 nM。EN219 可在体外实验中抑制 RNF114 介导的自泛素化和 p21 泛素化(50 μM)。在 1 μM 条件下,EN219 可与包括微管 β1 链(TUBB1)、热休克蛋白 60(Hsp60/HspD1)及组蛋白 H3.1 (HIST1H3A) 在内的多种蛋白相互作用(231MFP 乳腺癌细胞)。此外,EN219 可与溴结构域抑制剂 (+)-JQ1 偶联,构建可降解 BRD4 的 PROTAC。

产品描述 | EN219 is a synthetic recruiter of the E3 ubiquitin ligase RNF114 and binds specifically to cysteine 8 (C8) within its intrinsically disordered region, exhibiting an IC50 of 470 nM. EN219 inhibits RNF114-induced autoubiquitination and p21 ubiquitination in cell-free assays at 50 μM. At 1 μM, EN219 interacts with multiple proteins including the tubulin β1 chain (TUBB1), heat shock protein 60 (Hsp60/HspD1), and histone H3.1 (HIST1H3A) in 231MFP breast cancer cells. Furthermore, EN219 has been linked to the bromodomain inhibitor (+)-JQ1 for the creation of a PROTAC capable of degrading BRD4 in 231MFP cells. |
