In this issue of Molecular Cell, Yanagiya et al. (2012) describe a regulatory mechanism that couples the abundance of the translational repressor 4E-BP1 with its target eIF4E via proteasomal degradation of 4E-BP1, thus maintaining translation in cells depleted of eIF4E.
在本期《分子细胞》中,Yanagiya 等人(2012)描述了一个调控机制,通过蛋白酶体降解 4E-BP1 将翻译抑制剂 4E-BP1 的丰度与其靶标 eIF4E 偶联起来,从而在 eIF4E 耗竭的细胞中维持翻译。
