Function |
Ligand-activated non-selective calcium permeant cation channel involved in detection of noxious chemical and thermal stimuli. Seems to mediate proton influx and may be involved in intracellular acidosis in nociceptive neurons. Involved in mediation of inflammatory pain and hyperalgesia. Sensitized by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases, which involves PKC isozymes and PCL. Activation by vanilloids, like capsaicin, and temperatures higher than 42 degrees Celsius, exhibits a time- and Ca(2+)-dependent outward rectification, followed by a long-lasting refractory state. Mild extracellular acidic pH (6.5) potentiates channel activation by noxious heat and vanilloids, whereas acidic conditions (pH <6) directly activate the channel. Can be activated by endogenous compounds, including 12-hydroperoxytetraenoic acid and bradykinin. Acts as ionotropic endocannabinoid receptor with central neuromodulatory effects. Triggers a form of long-term depre

Tissue Specificity |
Predominantly expressed in trigeminal and dorsal root sensory ganglia. Expressed also in hippocampus, cortex, cerebellum, olfactory bulb, mesencephalon and hindbrain. High expression in the cell bodies and dendrites of neurons in the hippocampus and in the cortex. In the brain detected also in astrocytes and pericytes. Isoform 1 and isoform 3 are expressed in brain and peripheral blood mononuclear cells. {ECO:0000269|PubMed:10644739, ECO:0000269|PubMed:15857679, ECO:0000269|PubMed:9349813}.
