Calcium and ATP control multiple vital functions

Abstract excerpt

Life on Planet Earth, as we know it, revolves around adenosine triphosphate (ATP) as a universal energy storing molecule. The metabolism of ATP requires a low cytosolic Ca(2+) concentration, and hence tethers these two molecules together. The exceedingly low cytosolic Ca(2+) concentration (which in all life forms is kept around 50-100 nM) forms the basis for a universal intracellular signalling system in which...
