Protein homeostasis in higher eukaryotes is balanced by a dynamic network of adaptive mechanisms, including the unfolded protein response (UPR) and autophagy. In a paper recently published in Cell Research, Zhu and co-workers uncover a novel biological function of the unspliced form of the UPR transcription factor XBP1 in the modulation of autophagy through the control of FoxO1 turnover.
在高等真核生物中,蛋白质动态平衡是通过一个由适应性机制组成的动态网络来维持的,包括未折叠蛋白反应(UPR)和自噬。在最近发表在《Cell Research》上的一篇论文中,朱博士及其同事揭示了 UPR 转录因子 XBP1 的未剪接形式通过控制 FoxO1 周转来调节自噬的新生物学功能。
