1 Transient Receptor Potential vanilloid 1 (TRPV1) ion channel serves as the detector for noxious temperature above 42 C, pungent chemicals like capsaicin and acidic extracellular pH. Capsaicin transient receptor potential cation channel subfamily V member 1 Homo sapiens
2 Transient Receptor Potential vanilloid 1 (TRPV1) ion channel serves as the detector for noxious temperature above 42 C, pungent chemicals like capsaicin and acidic extracellular pH. Capsaicin transient receptor potential cation channel subfamily V member 1 Homo sapiens
3 We found that these endocannabinoid ligands bind to the vanilloid binding pocket of TRPV1 in the "tail-up, head-down" configuration, similar to capsaicin; however, there is a unique interaction with TRPV1 Y512 residue critical for endocannabinoid activation of TRPV1 channels. Capsaicin transient receptor potential cation channel subfamily V member 1 Homo sapiens
4 We found that these endocannabinoid ligands bind to the vanilloid binding pocket of TRPV1 in the "tail-up, head-down" configuration, similar to capsaicin; however, there is a unique interaction with TRPV1 Y512 residue critical for endocannabinoid activation of TRPV1 channels. Capsaicin transient receptor potential cation channel subfamily V member 1 Homo sapiens
5 These data suggest a differential structural mechanism is involved in TRPV1 activation by endocannabinoids compared to the classic agonist capsaicin. Capsaicin transient receptor potential cation channel subfamily V member 1 Homo sapiens
