P2X receptors are a family of cation-permeable ligand gated ion channels that open in response to the binding of extracellular adenosine 5′-triphosphate (ATP). They belong to a larger family of receptors known as the purinergic receptors. P2X receptors are present in a diverse array of organisms including humans mouse rat rabbit chicken zebrafish bullfrog fluke and amoeba.
