Capsaicin receptor, termed vanilloid receptor subtype 1 (VR1), has been cloned from sensory neurons.
VR1 protein is a heat-gated cation channel.
VR1 is also activated by noxious heat (elevation in temperature causing pain) and high proton concentrations (pH <6.0).
Rat VR1 encodes a membrane protein of 838aa (~95kD) with 6 transmembrane domains.
VR1 expression is limited to small to medium diameter primary sensory neurons.
Recently, a structural homolog of VR1, termed VRL-1 (VR1 like proteins; rat 761aa, human 764aa) have been cloned and characterized.
There is ~49% identity between VRL-1 and VR1.
In contrast to VR1, VRL-1 does not respond to capsaicin, acid or moderate heat.
Instead, it is activated by high temperatures with a threshold of ~52°C.
Within sensory ganglia, VRL-1 is most prominently expressed by a subset of medium to large-diameter neurons, and in many non-neuronal tissues (lung, spleen and intestine) that are unlikely to encounter temperatures of >50°C.
It is possible that VRL-1 is also activated by stimuli other than heat.
