All living organisms depend on P-type ATPase to pump cation across the membrane. They play a fundamental role in their metabolism and physiology. Ca2+ ATPase, a P-type ATPase, transports calcium ions across the membrane against a concentration gradient. These pumps clear cytoplasm of the second messenger, the calcium. It's very important to keep a low concentration of calcium in the cell for a good cell signaling. | All living organisms depend on P-type ATPase to pump cation across the membrane.
