Adenosine 5μ-triphosphate (ATP) is a key energy currency, with high phosphate transfer potential, in all living organisms. ATP participates in several biological processes such as membrane transport, muscle contraction and synthesis, and degradation of biological molecules. It serves as an intracellular and extracellular signaling molecule in certain cellular processes such as cell motility, organ development, neurotransmission, and insulin secretion. Adenosine 5μ-triphosphate (ATP) acts as a substrate for proteins of the kinesin superfamily.
