Description

purinergic receptor P2X, ligand-gated ion channel, 3

Gene Summary

Enables extracellularly ATP-gated monoatomic cation channel activity. Involved in modulation of chemical synaptic transmission. Acts upstream of or within several processes, including neuromuscular synaptic transmission; response to ATP; and smooth muscle contraction. Located in axon. Is active in Schaffer collateral - CA1 synapse and hippocampal mossy fiber to CA3 synapse. Is expressed in several structures, including branchial arch; embryo ectoderm; gut; nervous system; and retina. Orthologous to human P2RX3 (purinergic receptor P2X 3).
