WebPDB entry 5is0 shows TRPV1 bound to a molecule that resembles capsaicin. The molecule binds in a pocket between subunits, near one of the gates that control ion flux through the channel pore. This structure was determined by purifying the channel and inserting it into lipid nanodiscs, which were then examined using electron cryo-microscopy. WebVanilloids are pain evoking molecules that serve as ligands of the “heat and capsaicin receptor” TRPV1. Binding of either endogenous or exogenous vanilloids evokes channel and subsequent neuronal activation, leading to pain sensation. Despite its pivotal physiological role, the molecular basis of TRPV1 activation and deactivation is not fully …
