Potentiates activation of mammalian TRPA1, a non-selective cation channel involved in perception of pain, in vitro yet has an analgesic and anti-inflammatory effect in vivo. Has antibacterial activity against C.glutamicum (MIC=50 uM) and, to a lesser extent, against S.aureus but not against P.aeruginosa or E.coli. Detected in mucus secreted from ectoderm. Has no effect on mammalian TRPV1 and TRPV3. Belongs to the Cnidaria small cysteine-rich protein (SCRiP) family.
