Summary: Enables calcium channel activity. Involved in several processes, including cellular response to food; detection of mechanical stimulus involved in sensory perception; and intracellular calcium ion homeostasis. Acts upstream of or within several processes, including detection of stimulus involved in sensory perception of pain; response to hydrogen peroxide; and thermoception. Located in stereocilium bundle. Is active in plasma membrane. Is expressed in cochlea; dorsal root ganglion; glossopharyngeal ganglion; and lumbar dorsal root ganglion. Human ortholog(s) of this gene implicated in familial episodic pain syndrome 1. Orthologous to human TRPA1 (transient receptor potential cation channel subfamily A member 1).

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.
