2025 年 5 月 6 日,加州大学伯克利分校 Michael Rapé 团队 (博士后 Zhi Yang 为第一作者) 在国际顶尖学 术期刊 Nature 上发表了题为: Molecular basis of SIFI activity in the integrated stress response 的研究论文。 研究团队 将内源性 SIFI 的冷冻电镜结构解析、AlphaFold 建模以及生化分析相结合,揭示了整合应激反应 (ISR) 沉默的结构和机制基础 。 撰文丨王聪 编辑丨王多鱼 排版丨水成文 慢性应激反应的激活会损害细胞存活,并导致严重的退行性疾病。因此,生物体相应地会部署诸如 E3 泛素 连接酶 SIFI 等沉默因子,以终止应激反应信号传导并确保细胞内稳态。 然而,一种沉默因子如何在细胞尺度上感知应激压力以及及时使应激反应失活,这一点尚不清楚。 当细胞遭遇压力 (例如线粒体损伤、蛋白质错误折叠) ,它会启动" 整合应激反应 " (ISR) ,暂停非必 需活动,集中资源修复损伤。但如果警报不及时关闭,持续激活的应激反应反而会"误伤"细胞,导致神经退 行性疾病。 在这项发表于 Nature 期 ...
