All living organisms use ion channels to regulate the transport of ions across cellular membranes. Certain ion channels are classed as voltage-dependent because they have a voltage-sensing structure that induces their pores to open in response to changes in the cell membrane voltage. Until recently, the voltage-dependent K+, Ca2+ and Na+ channels were regarded as a unique development of eukaryotic cells, adapted to accomplish specialized electrical signalling, as exemplified in neurons. Here we… CONTINUE READING
