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]. 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 .
