A model for cap snatching at the nucleopore. The interaction of TSWV nucleocapsid (N) protein with RanGAP is indicated. N protein localizes at the nucleopore through interaction with RanGAP and thereby acquires access to the capped RNA molecules involved in RanGAP/RanBP-mediated transportation, and to the mRNA pool (resulting from GLE/DDX19-mediated transportation) in the exclusion zone of the nuclear pore complex at which cap binding protein exchanges with eIF4E, and continues trafficking to the cytosol.
