TRPA1

transient receptor potential cation channel, subfamily A, member 1

Receptor-activated non-selective cation channel involved in detection of pain and possibly also in cold perception and inner ear function. Has a central role in the pain response to endogenous inflammatory mediators and to a diverse array of volatile irritants, such as mustard oil, garlic and acrolein, an irritant from tears gas and vehicule exhaust fumes. Acts also as a ionotropic cannabinoid receptor by being activated by delta(9)-tetrahydrocannabinol (THC), the psychoactive component of marijuana. Not involved in menthol sensation. May be a component for the mechanosensitive transduction channel of hair cells in inner ear, thereby participating in the perception of sounds. Probably operated by a phosphatidylinositol second messenger system.

Gene Name: transient receptor potential cation channel, subfamily A, member 1
Family/Subfamily: Ion Channel , Calcium channel - TRP
Synonyms: TRPA1, ANKTM1, TRPA-1
Target Sequences: NM_007332 CAA71610.1 O75762
