The role of nucleocytoplasmic transport in mechanotransduction.

Cells integrate mechanical and biochemical signals via a process called mechanotransduction to generate essential gene expression patterns in space and time. This is vital for cell migration and proliferation as well as tissue morphogenesis and remodeling. While the force-sensing and force-transducing mechanisms are generally known, it remains unclear how mechanoresponsive transcription factors (TFs) are selectively translocated into the nucleus upon force-activation. Such TFs include Yes-Associated Protein (YAP), Myocardin Related Transcription Factor (MRTF), Hypoxia Induced Factors (HIF) and others. Here, we discuss how the nucleocytoplasmic transport (NCT) machinery intersects with mechanoresponsive TFs to facilitate their selective transport through nuclear pore complexes (NPCs).
