Previous GeneCards Identifiers 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]

UniProtKB/Swiss-Prot Summary for P2RX4 Gene
Receptor for ATP that acts as a ligand-gated ion channel. This receptor is insensitive to the antagonists PPADS and suramin.
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.
