WebJul 1, 2024 · 3. RNPs shuttling functions. The nuclear location of RBPs depends on the presence of nuclear location signals (NLSs). The export of the RBPs bound to mRNA could, however, be based on nuclear export sequences (NESs) in proteins or could, alternatively, result from passive “piggy backing” on mRNA [6].
