specialized proteins that regulate calcium ion flow in cells
Calcium channels, also known as Ca2+ channels, are specialized protein structures embedded in cell membranes that regulate the flow of calcium ions (Ca2+) into and out of cells. These channels play a crucial role in various physiological processes, including muscle contraction, neurotransmitter release, and gene expression. By controlling calcium ion movement, they help maintain cellular functions and signaling pathways essential for health and disease management.
