WebMay 12, 2024 · Dysregulation of shuttling proteins leads to mislocalization of proteins, which is relevant to several diseases. It has been reported that more and more shuttling proteins such as transcription factors, cell cycle regulators and other functional proteins are also found in a variety of diseases. 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 .
