Abstract:
The different concentration of specific ion species and the electrodiffusion of the ions down their electrochemical gradient generate transmembrane potential. The regulation of membrane potential for the function of numerous membrane proteins such as ion channels, transporters, pumps and enzymes plays primary role in the conversion of extracellular electric stimulation into a sequence of intracellular biochemical signals. Some ion channels regulated by membrane potential are well known, and the membrane non-ion channels protein is also modulated physiologically by membrane potential.

Non-gated Ion Channels
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism.

Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...
