General annotation (Comments)

Function

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. Ref.1 Ref.4 Ref.6 Ref.7

Enzyme regulation

Inhibited by ruthenium red, a potent blocker of TRPV channels.

Subcellular location

Membrane; Multi-pass membrane protein Probable.

Tissue specificity

Expressed in inner ear (at protein level). Specifically expressed in a subset of nociceptive neurons. Expressed in the same neurons that TRPV1. In contrast, it is not expressed in neurons expressing TRPM8. Expressed in the superior cervical ganglion. Ref.1 Ref.4 Ref.5 Ref.7

Developmental stage

During utricle development, it is first expressed at E15 and E16 and peaks at E17. It drops at E18 but increases again at E19, possibly corresponding to a second wave of hair cells that are generated at E15. Ref.4

Disruption phenotype

Mice display normal cold sensitivity and unimpaired auditory function, suggesting that this channel is not required for the initial detection of noxious cold or sound. However, they exhibit pronounced deficits in bradykinin-evoked nociceptor excitation and pain hypersensitivity. Ref.8

Sequence similarities

Belongs to the transient receptor (TC 1.A.4) family. [View classification]

Contains 14 ANK repeats.
