Nuclear Import and Export Signals

  • Chapter

Part of the Molecular Biology Intelligence Unit book series (MBIU)

Abstract

Eukaryotic cells are separated into two large compartments, namely the nucleus and the cytoplasm, by the nuclear envelope. As a result, macromolecules including RNAs, which are transcribed in the nucleus and nuclear proteins, which are translated in the cytoplasm must cross the double Upid bilayer to reach the intracellular sites where they function. In addition, cumulative evidence suggests that trafficking between the nucleus and the cytoplasm is rather dynamic and some proteins and RNAs cross the nuclear envelope again after being transported to one compartment.
