methyltransferase that represses the functional activity of the tumor suppressor proteins p53 and RB. HTS screening led to identification of five distinct substrate-competitive chemical series. Determination of liganded crystal structures of SMYD2 contributed significantly to “hit-to-lead” design efforts, culminating in the creation of potent and selective inhibitors that were used to understand the functional
蛋白质赖氨酸甲基转移酶(KMT)已成为表观遗传信号的重要调节剂。这些酶催化供体甲基从辅因子S-腺苷甲硫氨酸转移到组蛋白上的特定受体赖氨酸残基上,从而导致染色质结构和转录调控的改变。这些酶还使一系列非组蛋白蛋白甲基化,表明它们影响细胞生理的其他机制。据报道,SMYD2是一种致癌甲基转移酶,可抑制肿瘤抑制蛋白p53和RB的功能活性。HTS筛选导致鉴定出五个不同的底物竞争性化学系列。SMYD2配体晶体结构的确定显着有助于“铅中毒”设计工作,最终创造出了有效的和选择性的抑制剂,这些抑制剂用于了解SMYD2抑制的功能后果。综上所述,这些结果对于针对KMT的抑制剂设计具有广泛的意义,并清楚地证明了开发针对这些酶的新型疗法的潜力。
