Figure 3From: Karyopherin binding interactions and nuclear import mechanism of nuclear pore complex protein TprThe binding of importin β to Tpr in the solid phase assay is sensitive to RanGTP. The binding of 100 nM importin β to Tpr adsorbed to microtiter wells was analyzed in the absence, or in the presence of 0.1, 0.2, 0.5 and 1 μM RanGMP-PNP or RanGDPβS, as indicated. The bound importin β was quantified as described in materials and methods.Back to article page
