The protein encoded by this gene belongs to the P2X family of G-protein-coupled receptors. These proteins can form homo-and heterotimers and function as ATP-gated ion channels and mediate rapid and selective permeability to cations. This protein is primarily localized to smooth muscle where binds ATP and mediates synaptic transmission between neurons and from neurons to smooth muscle and may being responsible for sympathetic vasoconstriction in small arteries, arterioles and vas deferens. Mouse studies suggest that this receptor is essential for normal male reproductive function. This protein may also be involved in promoting apoptosis. [provided by RefSeq, Jun 2013]
GeneCards Summary for P2RX1 Gene
P2RX1 (Purinergic Receptor P2X, Ligand Gated Ion Channel, 1) is a Protein Coding gene. Diseases associated with P2RX1 include p2y12 defect and bleeding disorder, platelet-type, 8. Among its related pathways are CREB Pathway and Platelet homeostasis. GO annotations related to this gene include ion channel activity and calcium channel activity. An important paralog of this gene is P2RX5-TAX1BP3.
UniProtKB/Swiss-Prot for P2RX1 Gene
Ligand-gated ion channel with relatively high calcium permeability. Binding to ATP mediates synaptic transmission between neurons and from neurons to smooth muscle. Seems to be linked to apoptosis, by increasing the intracellular concentration of calcium in the presence of ATP, leading to programmed cell death (By similarity).
P2X receptors are members of the ligand-gated ion channel family that open in response to extracellular ATP. Each receptor is made up of a trimer of subunits (P2X1-7) all of which share the common structure of two transmembrane domains.
