{{Infobox_gene}}P2X purinoceptor 1 is a protein that in humans is encoded by the P2RX1 gene.[1]The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel with relatively high calcium permeability. Expressed in smooth muscle and platelets. Binding to ATP mediates synaptic transmission between neurons and from neurons to smooth muscle, being responsible, for example, for sympathetic vasoconstriction in small arteries, arterioles and vas deferens. Mouse studies suggest that this receptor is essential for normal male reproductive function. It is possible that the development of selective antagonists for this receptor may provide an effective non-hormonal male contraceptive pill.[2] See alsoReferences1. ^{{cite journal | vauthors = Valera S, Talabot F, Evans RJ, Gos A, Antonarakis SE, Morris MA, Buell GN | title = Characterization and chromosomal localization of a human P2X receptor from the urinary bladder | journal = Receptors Channels | volume = 3 | issue = 4 | pages = 283–9 |date=Nov 1996 | pmid = 8834001 | pmc = | doi = }}
