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; nervous system; retina; and skin. Orthologous to human P2RX3 (purinergic receptor P2X 3).

Data suggest that the negative inhibition of P2X3R activity by the BNP/NPR-A pathway results in a decreased P2X3R-mediated excitability of trigeminal neurons in wildetype cultures. In familial hemiplegic migraine type-1 model cultures, however, lack of efficient P2X3Rs downregulation contributes to the neuronal hyperexcitability phenotype.

P2X3 receptors on mouse trigeminal ganglion neurons are subjected to contrasting modulation by inhibitory brain natriuretic peptide and facilitatory calcitonin gene-related peptide that both operate via complex intracellular signaling.
Title: Inefficient constitutive inhibition of P2X3 receptors by brain natriuretic peptide system contributes to sensitization of trigeminal sensory neurons in a genetic mouse model of familial hemiplegic migraine.
mouse trigeminal neurons endogenous BNP acts on NPR-A receptors to determine constitutive depression of P2X3 receptor function. Tonic inhibition of P2X3 receptor activity by BNP/NPR-A/PKG pathways occurs via two distinct mechanisms: P2X3 serine phosphorylation and receptor redistribution to non-raft membrane compartments

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
