TRPV1
Human protein for regulating body temperature / From Wikipedia, the free encyclopedia
The transient receptor potential cation channel subfamily V member 1 (TRPV1), also known as the capsaicin receptor and the vanilloid receptor 1, is a protein that, in humans, is encoded by the TRPV1 gene. It was the first isolated member of the transient receptor potential vanilloid receptor proteins that in turn are a sub-family of the transient receptor potential protein group.[5][6] This protein is a member of the TRPV group of transient receptor potential family of ion channels.[7] Fatty acid metabolites with affinity for this receptor are produced by cyanobacteria, which diverged from eukaryotes at least 2000 million years ago (MYA).[8] The function of TRPV1 is detection and regulation of body temperature. In addition, TRPV1 provides a sensation of scalding heat and pain (nociception). In primary afferent sensory neurons, it cooperates with TRPA1[9][10] (a chemical irritant receptor) to mediate the detection of noxious environmental stimuli.[11]
