BK Channel

BK channels, also known as big potassium channels, are specialized proteins found in cell membranes that help regulate electrical activity by allowing potassium ions to flow out of the cell. This flow influences the cell's electrical state, helping control processes like muscle contraction, nerve signaling, and hormone release. They are called "big" because they are larger and respond to multiple signals such as voltage changes and calcium levels. By doing so, BK channels play a crucial role in maintaining proper cellular function and overall coordination of physiological responses.
