Inhibition of endogenous karyopherin α export by Nup153-C, but not by Nup153-Cr or NLS peptides. After a 30 min incubation in the export reaction with either 3 μM Ran alone or together with 250 μM Nup153-C, or 250 μM Nup153-Cr, or 250 μM NLS, export of karyopherin α was quantitated as described in Fig. 1A.
