| Outline of Final Research Achievements |
In this study, we tried to clarify voltage-sensing mechanism of the voltage-gated channels which generate and regulate bioelectronic signals as represented by the heartbeat and brain functions. We focused on the voltage-gated H+ channel consisting of a minimum voltage-sensor unit, and analyzed the voltage-sensor movement by membrane voltage and the structural rearrangement toward the channel opening. We demonstrated the molecular basis of the voltage-sensing mechanism.
