Tiivistelmä

Paxillin is a potential participant in the direct intracellular force transmission which is considered as the foundation of cells sensing and responding to extracellular environment. However, the detection of tension across paxillin has not been achieved due to lacking microsized tools. Herein, a paxillin tension sensor (PaxTs) based on Fluorescence Resonance Energy Transfer (FRET) technique was constructed. PaxTs can be expressed and assembled to FA sites spontaneously to visualize the tension across paxillin with FRET efficiency of ~62.4% in living cells. The tension across paxillin was found to decrease upon shear stress, in which the membrane fluidity and contractility of actin acted as cushions. It is observed that paxillin participates in the pathway of cell membrane-cytoskeleton-FAs for force transmission upon mechanical force in real time visualization, which provides a promising new method to investigate the direct intracellular force transmission in biology and technology.
