Description:
TRPA1 is a member of the transient receptor potential (TRP) family of ion channels that act as sensors of a wide range of cellular and environmental signals and mediate pain sensitivity. There are seven TRP protein sub-families; TRPA (ankyrin), TRPV (vanilloid), TRPC (canonical), TRPP (polycystin), TRPM (melastatin), TRPML (mucolipin), and TRPN (NOMPC-like; only in invertebrates and fish). TRP channels contain six-transmembrane polypeptide subunits forming tetramers with a central ion conducting pore. TRPA1 also has 17 ankyrin repeats in the N-terminal region. The TRPA1 receptor is activated by diverse sensory processes, including noxious cold (17 °C), pungent ingredients of natural products (e.g., cinnamon oil, wintergreen oil, clove oil, mustard oil, and ginger), environmental irritants (e.g., acrolein), and inflammatory agents (e.g., bradykinin). TRPA1 function is modulated by phospholipase C activity. TRPA1 is expressed in small-diameter neurons of the trigeminal and dorsal root ganglia (DRGs), as well as in the hair cells of the inner ear. TRPA1 plays a major role in the generation and/or maintenance of inflammatory and neuropathic pain. It is implicated in the etiology of familial episodic syndrome (FEPS). Genetic variants of TRPA1 associated with utilization rate in sickle cell disease (SCD), i.e., the number of emergency department/acute care center admissions as a result of SCD pain crisis.
