Caterina et al has identified a structurally related receptor, VRL-1, that does not respond to capsaicin, acid or moderate heat. Instead, VRL-1 is activated by high temperatures, with a threshold of approximately 52 degrees C. Within sensory ganglia, VRL-1 is most prominently expressed by a subset of medium- to large-diameter neurons, making it a candidate receptor for transducing high-threshold heat responses in this class of cells. VRL-1 transcripts are not restricted to the sensory nervous system, indicating that this channel may be activated by stimuli other than heat. VRL-1 is one of the six members of the vanilloid-like TRP-channel family which is now known as TRPV family. FUNCTION: Calcium-permeable, non-selective cation channel with an outward rectification. Seems to be regulated, at least in part, by growth factors, like IGF1, PDGF and morphogenetic neuropeptide/head activator. May transduce physical stimuli in mast cells. Activated by temperatures higher than 52 degrees Celsius; is not activated by vanilloids and acidic pH. SUBUNIT: Homotetramer (Probable). Interacts with a cAMP-dependent protein kinase type II regulatory subunit (PRKAR2A or PRKAR2B) and ACBD3. Interacts with RGA. SUBCELLULAR LOCATION: Cell membrane; multi-pass membrane protein. Cytoplasm. Translocates from the cytoplasm to the plasma membrane upon ligand stimulation. TISSUE SPECIFICITY: Ubiquitously expressed. Expressed in dorsal root ganglia, trigeminal ganglia, spinal chord (Lissauer's tract, dorsal horn and dorsal columns) (at protein level). PTM: N-glycosylated. PTM: Phosphorylated by PKA. SIMILARITY: Belongs to the transient receptor family. TrpV subfamily. SIMILARITY: Contains 3 ANK repeats.
