BK Channels

BK channels, or big potassium channels, are specialized proteins found in cell membranes that allow potassium ions to flow in and out of cells. They play a crucial role in regulating electrical signals within cells, particularly in nerve and muscle tissues. By controlling the flow of potassium, BK channels help manage processes like muscle contraction and nerve transmission. Their activity is influenced by various factors, including voltage changes and calcium levels, making them essential for maintaining proper cellular function and responding to physiological demands.
