Cav2.1 (P/Q-type calcium channel)

Cav2.1, also known as P/Q-type calcium channel, is a protein found in nerve cells that helps control the flow of calcium ions into the cell. These calcium ions are essential for transmitting signals, especially in communication between nerve cells and muscles. When a nerve signal reaches the nerve ending, Cav2.1 channels open to allow calcium to enter, which then triggers the release of chemicals that carry messages. This process is vital for functions like muscle movement, brain activity, and hormone release. Proper functioning of Cav2.1 channels is crucial for normal nervous system operation.
