| Research Abstract |
A membrane potential control device, which induces the conformational changes of prestin expressed in the plasma membrane, has been newly developed. Microstructures and electrophysiological properties of the prestin-expressing culture cells and the prestin-reconstituted lipid bilayer were measured by using this device. As a result, it was suggested that the conformational changes of proteins in the plasma membrane may possibly be visualized when the membrane potential is controlled using the developed device. Based on the findings obtained in this study, further research to visualize the conformational changes of prestin reconstituted in the lipid bilayer will be performed using this device.
