Almost all living things contain potassium channels, which are the most common type of ion channel. They build pores across cell membranes that are selective for potassium. The majority of cell types contain potassium channels, which regulate a wide range of cellular activities. Potassium channels work to quickly and selectively conduct potassium ions down their electrochemical gradient. In many cells, these channels function to either set or reset the resting potential. The delayed counterflow of potassium ions in excitable cells, like neurons, shapes the action potential. Failure of potassium channels can lead to potentially fatal arrhythmias by helping to control the duration of the action potential in cardiac muscle. Maintaining vascular tone may also involve potassium channels.
