Structural insights into the molecular mechanism of mouse TRPA1 activation and inhibition

Pain, though serving the beneficial function of provoking a response to dangerous situations, is an unpleasant sensory and emotional experience. Transient receptor potential ankyrin 1 (TRPA1) is a member of the transient receptor potential (TRP) cation channel family and is localized in "nociceptors," where it plays a key role in the transduction of chemical, inflammatory, and neuropathic pain. TRPA1 is a Ca2+-permeable, nonselective cation...
