In this issue of Molecular Cell, Benvegnù et al. (2017) report an unexpected phenomenon by which the E3 ligase mahogunin ring finger-1 (MGRN1) translocates to the nucleus in an age-dependent manner, revealing an intriguing mechanism that allows for an adaptive neuronal response to proteotoxic stress, often seen with aging.
在本期《分子细胞》中,Benvegnù 等人(2017)报道了一个出人意料的现象,即 E3 连接酶 mahogunin 环指蛋白 1(MGRN1)会随着年龄的增长而出现核转位,揭示了一种允许神经元对蛋白质毒性应激做出适应性反应的有趣机制,这种现象通常随着衰老而出现。
