Anion channels

Anion channels are specialized protein structures in cell membranes that allow negatively charged ions, called anions (like chloride), to pass in or out of the cell. They help regulate cell activities such as maintaining electrical balance, controlling fluid movement, and transmitting signals between cells. When these channels open, they enable the flow of anions, influencing processes like nerve signaling and muscle contraction. Proper functioning of anion channels is essential for overall cell health and communication.
