    Summary
    Enables mechanosensitive monoatomic ion channel activity and monoatomic cation channel activity. Involved in detection of mechanical stimulus involved in sensory perception and monoatomic cation transport. Acts upstream of or within regulation of membrane potential. Located in cuticular plate; neuronal cell body membrane; and stereocilium. Is expressed in dorsal root ganglion and lung. Human ortholog(s) of this gene implicated in distal arthrogryposis type 3 and distal arthrogryposis type 5. Orthologous to human PIEZO2 (piezo type mechanosensitive ion channel component 2).

    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.
