Summary: Enables extracellularly ATP-gated cation channel activity. Involved in sensory perception of sound. Acts upstream of or within several processes, including response to ATP; skeletal muscle fiber development; and smooth muscle contraction. Located in plasma membrane. Is expressed in facial ganglion; heart; medulla oblongata basal plate mantle layer; and vagus ganglion. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 41. Orthologous to human P2RX2 (purinergic receptor P2X 2). [provided by Alliance of Genome Resources, Apr 2022]

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.
