Regulation of RNA transport out of the nucleus Only 1/20 th of the total mass of RNA synthesized ever leaves the nucleus Nuclear pore complexes or nucleoporins, regulate what enters and leaves the cell Nuclear import/export signals receptors signal to nucleoporins macromolecules to be imported/exported out of the nucleus Proteins Ran-GEF and Ran-GAP, and Ran-GTP imposes directionality on transport through nucleoporins
