Potassium channels constitute a highly diverse class of ion channel and thus participate in multiple modulatory functions. There are several functional types of K+ channel, including voltage-gated K+ channels, Ca2+-activated K+ channels, inward rectifiers, leak K+ channels and Na+-activated K+ channels. Principal or pore-forming subunits of at least the first four types have been identified and are classified into three groups of proteins on the basis of their structural properties.
