Probable ion channel inhibitor. Shows insecticidal activity. Acts synergistically with the neonicotinoid insecticide imidacloprid. Is neither a repellent that repels insects nor an attractant that is preferentially consumed by insects. Is very stable. Expressed by the venom gland. The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. LD(50) is 1.84 +-0.8 nmol/g in mealworm. LD(50) is 170.5 +- 0.2 nmol/g when orally administered into mealworm. LD(50) is 104.2 +-0.6 pmol/g when orally administred into the cotton bollworm H.armigera. Belongs to the neurotoxin 14 (magi-1) family. OAIP-1 subfamily.
