Abstract

Yang et al. unravel the molecular mechanism by which the tumor suppressor BAP1 is shuttled into the nucleus by TNPO1. TNPO1 sterically competes with UBE2O for monoubiquitination sites within the nuclear localization sequence of BAP1 to prevent its cytoplasmic retention.

肿瘤抑制因子BAP1的核输入受转运蛋白-1控制
Yang等人揭示了肿瘤抑制因子BAP1通过TNPO1转运进入细胞核的分子机制。在BAP1的核定位序列中,TNPO1与ube20在空间上竞争单泛素化位点,以防止其细胞质保留。
