Engineered mutants in the switch II loop of ran define the contribution made by key residues to the interaction with nuclear transport factor 2 (NTF2) and the role of this interaction in nuclear protein import

Nuclear protein import requires a precisely choreographed series of interactions between nuclear pore components and soluble factors such as importin-β, Ran, and nuclear transport factor 2 (NTF2). We used the crystal structure of the GDPRan-NTF2 complex to design mutants in the switch II loop of Ran...
