<p>ATP is an important molecule in the body that is involved in a number of cellular processes, including energy production and transmission. It has been shown to be tumorigenic and is found at high levels in plasma membranes and muscle cells. ATP binds to the adenylate cyclase enzyme in the cell membrane and stimulates its activity, which increases intracellular levels of cyclic AMP (cAMP). Cyclic AMP activates protein kinase A, which phosphorylates proteins, leading to a cascade of reactions that result in cellular changes. ATP also has pharmacological effects on the plasma membrane by increasing its permeability to certain ions such as potassium ions. This leads to an increase in the rate of depolarization of the cell membrane, which causes an influx of calcium ions into the cell.</p>
