1.A.4.2.9
The temperature (heat; >39°C)-sensitive, capsaicin-insensitive receptor cation-selective channel, TRPV3 or TRL3 (may form heterooligomers with VR1 (TRPV1; TC #1.A.4.2.1)). Incensole acetate, an incense component, elicits psychoactivity by activating TRPV3 channels in the brain (Moussaieff et al., 2008).  TRPV3 is activated by synthetic small-molecule chemicals and natural compounds from plants as well as warm temperatures. Its function is regulated by a variety of physiological factors including extracellular divalent cations and acidic pH, intracellular ATP, membrane voltage, and arachidonic acid. It shows a broad expression pattern in both neuronal and non-neuronal tissues including epidermal keratinocytes, epithelial cells in the gut, endothelial cells in blood vessels, and neurons in dorsal root ganglia and the CNS. TRPV3 null mice exhibit abnormal hair morphogenesis and compromised skin barrier function, and it may play critical roles in inflammatory skin disorders, itch, and pain sensation (Luo and Hu 2014).
