  • Primary antibody notesVanilloid Receptor 1 (VR1), also known as capsaicin receptor, responds to both capsaicin, the pungent ingredient in hot peppers, and thermal stimuli within the noxious temperature range. This receptor is structurally related to the TRP family of ion channels and is predicted to contain 6 trans-membrane domains, a P-loop membrane domain and 3 ankyrin repeat domains. VR1 is highly permeable to divalent cations, including calcium and magnesium, as well as the monovalent cations sodium and potassium. Expression of VR1 appears to be limited to neurons within the sensory ganglia.

  • FunctionReceptor-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. May be 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. Acts as ionotropic endocannabinoid receptor with central neuromodulatory effects. Triggers a form of long-term depression (TRPV1-LTD) mediated by the endocannabinoid anandamine in the hippocampus and nucleus accubens by affecting AMPA receptors endocytosis.
  • Tissue specificityWidely expressed at low levels. Expression is elevated in dorsal root ganglia. In skin, expressed in cutaneous sensory nerve fibers, mast cells, epidermal keratinocytes, dermal blood vessels, the inner root sheet and the infundibulum of hair follicles, differentiated sebocytes, sweat gland ducts, and the secretory portion of eccrine sweat glands (at protein level).
  • Sequence similaritiesBelongs to the transient receptor (TC 1.A.4) family. TrpV subfamily. TRPV1 sub-subfamily.
    Contains 6 ANK repeats.
  • DomainThe association domain (AD) is necessary for self-association.
  • Post-translational
    Phosphorylation by PKA reverses capsaicin-induced dephosphorylation at multiple sites, probably including Ser-117 as a major phosphorylation site. Phoshphorylation by CAMKII seems to regulate binding to vanilloids. Phosphorylated and modulated by PKCM and probably PKCZ. Dephosphorylation by calcineurin seems to lead to receptor desensitization and phosphorylation by CAMKII recovers activity.
