Previous GeneCards Identifiers for P2RX7 Gene
The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel and is responsible for ATP-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Activation of this nuclear receptor by ATP in the cytoplasm may be a mechanism by which cellular activity can be coupled to changes in gene expression. Multiple alternatively spliced variants have been identified, most of which fit nonsense-mediated decay (NMD) criteria. [provided by RefSeq, Jul 2010]

Among its related pathways are CREB Pathway and Calcium signaling pathway. GO annotations related to this gene include protein homodimerization activity and magnesium ion binding. An important paralog of this gene is P2RX1.
UniProtKB/Swiss-Prot for P2RX7 Gene
Receptor for ATP that acts as a ligand-gated ion channel. Responsible for ATP-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Could function in both fast synaptic transmission and the ATP-mediated lysis of antigen-presenting cells
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, a large extracellular loop and intracellular C- and N-termini. Receptors can be formed from triplets of identical subunits (homomeric) and can also exist as heteromers. With the exception of P2X6, all subunits can form homomeric receptors. P2X receptors have a wide distribution throughout the body, including the central, peripheral and autonomic nervous systems, smooth muscle, heart and leukocytes. They are involved in a range of physiological processes such as modulation of synaptic transmission, vascular tone, cardiac rhythm and contractility and nociception.
