In all living cells, ion channels are required to regulate the membrane potential and intracellular ion concentrations. Functional ion channels allow movements of cations or anions across the membrane, which subsequently may influence a variety of cellular processes, such as proliferation, excitability, migration, apoptosis, secretion and others. Ion channels are specialized membrane proteins that span the plasma membrane. They form hydrophilic pores through which ions flow from one side of the membrane to the other down their electrochemical gradient.
