Vanilloid 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.
Applications:Suitable for use in Immunofluorescence and Immunohistochemistry.
