| Outline of Final Research Achievements |
Ion channel proteins are ion permeation pathway across cell membranes, whose functions are recorded with single-channel current recording method. The structure of KcsA potassium channel was first resolved at atomic resolutions among the ion channel proteins. We previously succeeded in recording conformational changes of the KcsA channel with the diffracted x-ray tracking method in a single-molecule level. In this study we tried to fabricate a new recording chamber and probes aiming to current-dynamics simultaneous recordings for the ion channel proteins.
