Transport of proteins, RNAs and ribonucleoprotein particles into and out of the nucleus is essential for many cellular functions to proceed. Recent progress in this area of research has led to the identification of a number of signals and cytosolic factors that mediate the nuclear import of proteins through the nuclear pore complexes. However, as the sites on the nuclear pore complex at which these signals and factors exert their function are still largely unidentified, the molecular mechanisms underlying this nuclear import pathway remain to be elucidated.
