Exportin-1 functions as an adaptor for transcription factor-mediated docking of chromatin at the nuclear pore complex
Many genes physically interact with the nuclear pore complex (NPC), which requires transcription factors (TFs). Ge et al. show that the exportin Crm1 binds TFs and nuclear pore proteins to dock chromatin at the NPC and to stimulate transcription. This function of Crm1 is distinct from its role in nuclear export.
