P2RX1 Membrane Protein Introduction

Introduction of P2RX1

P2X purinoceptor 1 (P2RX1) is a protein that is encoded by the P2RX1 gene in humans. P2RX1 gene is mapped to chromosome 17p13.3. P2RX1 belongs to the G-protein-coupled receptors P2X family, also known as ATP-gated P2X receptor cation channel family, consists of cation-permeable ion channels that are regulated by the binding of extracellular adenosine 5'-triphosphate. P2X receptors are found in many organisms including humans, rat, mouse, chicken, rabbit, bullfrog, zebrafish, fluke, and amoeba. P2RX1 has a broad expression in platelets and blood cells, urinary bladder, bone marrow, etc.

Function of P2RX1 Membrane Protein

Proteins of the P2X family can form hetero- and homotrimers and function as ATP-gated ion channels, which can regulate the selective permeability to cations. As a type of ATP-gated ion channel, P2RX1 is sensitive to the purinergic agonists ATP and alpha, beta-methylene ATP. P2RX1 seems to be involved in apoptosis, by changing the intracellular calcium concentration along with the consuming of ATP, leading to programmed cell death. It is reported that this receptor is required for normal male reproductive function in the mouse. Additionally, P2RX1 is also involved in many other biological processes, including blood coagulation, ceramide biosynthetic process, insemination, neutrophil degranulation, platelet activation, regulation of blood pressure, regulation of vascular smooth muscle contraction, and vasoconstriction. No experimental structure of P2RX1 is available, but a simulated trimer (Fig.1) can be found in the repository of SWISS-MODEL.
