Shuttling factors
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 . WebThe nucleocytoplasmic shuttling of transcription factors is a mechanism mediating this process. The activation and inactivation of the tran … To elicit the transcriptional response …
