Potassium channels are a group of ubiquitously expressed proteins that serve numerous functions in excitable and non-excitable cells. There are four major types of potassium channels, including calcium-activated, inwardly rectifying, tandem pore domain and voltage-gated. Voltage-gated potassium channels open and close in response to changes in transmembrane voltage and are important determinants of neuronal membrane excitability. Moreover, differences in potassium channel expression patterns and densities contribute to the variations in action potential waveforms and repetitive firing patterns evident in different neuronal cell types.
