WebTo investigate a possible involvement of Ran and other nucleocytoplasmic shuttling factors in nuclear export in our assay, we analyzed the stimulation of nuclear export of GFP–NFAT by Ran alone or by cytosol, after preincubation of the permeabilized cells either at 0°C or at 30°C in the presence of ATP and absence of cytosol (Fig. 5, a and b). WebE2F1 was identified as a key transcription factor modulating the expression of chromatin components in OPCs during the transition from proliferation to differentiation. Its nucleocytoplasmic shuttling was suggested to be required to dampen the E2F1-driven pattern of expression, thus allowing OPC differentiation to occur .

"WebAbstract. The partitioning of cells by a nuclear envelope ensures that precursors of ribosomes do not interact prematurely with other components of the translation machinery. Ribosomal subunits are assembled in nucleoli and exported to the cytoplasm in a CRM1/Ran-GTP-dependent fashion. Export of the large (60S) subunit requires a shuttling ... " - Shuttling factors
