Summaries for P2RX4 Gene

Entrez Gene Summary for P2RX4 Gene

  • The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel with high calcium permeability. The main pharmacological distinction between the members of the purinoceptor family is the relative sensitivity to the antagonists suramin and PPADS. The product of this gene has the lowest sensitivity for these antagonists. Multiple alternatively spliced transcript variants, some protein-coding and some not protein-coding, have been found for this gene. [provided by RefSeq, Feb 2012]

GeneCards Summary for P2RX4 Gene

P2RX4 (Purinergic Receptor P2X 4) is a Protein Coding gene. Diseases associated with P2RX4 include Chronic Pain. Among its related pathways are Platelet homeostasis and Ca, cAMP and Lipid Signaling. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and ion channel activity. An important paralog of this gene is P2RX1.

UniProtKB/Swiss-Prot for P2RX4 Gene

  • Receptor for ATP that acts as a ligand-gated ion channel. This receptor is insensitive to the antagonists PPADS and suramin.

Tocris Summary for P2RX4 Gene

  • 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.
