Importin-beta modulates the permeability of the nuclear pore complex in a Ran-dependent manner

Soluble karyopherins of the importin-beta (imp beta) family use RanGTP to transport cargos directionally through the nuclear pore complex (NPC). Whether imp beta or RanGTP regulate the permeability of the NPC itself has been unknown. In this study, we iden ...
