Ion channels are plasma proteins present in all types of cells. Ion channels determine membrane potentialsin nerve and muscle cells, contraction of muscle cells, and secretion in epithelial cells. Ion channels control intracellular Ca2+ thus affecting cell signals. In this lecture, ion channel genes are introduced along with their structures, biophysical properties and physiological functions. Furthermore, chronic diseases caused by mutations of channels will also be stressed, too. History on ion channels and membrane potentials will also be introduced.
