Potassium Channel
Potassium channels are a diverse group of ion channels that are predominantly involved in regulating the flow of potassium ions (K⁺) across cell membranes. These channels are essential for maintaining the cell’s electrical stability and controlling nerve impulses, muscle contractions, and heart rhythms. Potassium channels are categorized into several types, including voltage-gated, calcium-activated, and inward-rectifier potassium channels, each playing unique roles in cellular activities. Dysfunctions in these channels can lead to various medical conditions, such as epilepsy, arrhythmia, and diabetes. Due to their critical role in physiological processes, potassium channels are significant targets for drug development, aimed at treating a wide range of disorders involving electrical and cellular dysfunctions.
