== Publication Abstract from PubMed ==
Interactions with nucleoporins containing FxFG-repeat cores are crucial for the nuclear import of RanGDP mediated by nuclear transport factor 2 (NTF2). We describe here the 1.9 A resolution crystal structure of yeast NTF2-N77Y bound to a FxFG-nucleoporin core, which provides a basis for understanding this interaction and its role in nuclear trafficking. The two identical FxFG binding sites on the dimeric molecule are formed by residues from each chain of NTF2. Engineered mutants at the interaction interface reduce the binding of NTF2 to nuclear pores and cause reduced growth rates and Ran mislocalization when substituted for the wild-type protein in yeast. Comparison with the crystal structure of FG-nucleoporin cores bound to importin-beta and TAP/p15 identified a number of common features of their binding sites. The structure of the binding interfaces on these transport factors provides a rationale for the specificity of their interactions with nucleoporins that, combined with their weak binding constants, facilitates rapid translocation through NPCs during nuclear trafficking.

Function

NTF2_HUMAN Facilitates protein transport into the nucleus. Interacts with the nucleoporin p62 and with Ran. Acts at a relatively late stage of nuclear protein import, subsequent to the initial docking of nuclear import ligand at the nuclear envelope. Could be part of a multicomponent system of cytosolic factors that assemble at the pore complex during nuclear import.
