Shuttling factors
WebNuclear transport refers to the mechanisms by which molecules move across the nuclear membrane of a cell. The entry and exit of large molecules from the cell nucleus is tightly controlled by the nuclear pore complexes (NPCs). Although small molecules can enter the nucleus without regulation, macromolecules such as RNA and proteins require … 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 .

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 ...
