CC   -!- FUNCTION: Insect active toxin causing rapid but reversible paralysis in
CC       crickets. No activity shown in mammals. Does not show effect on
CC       mammalian voltage-gated calcium channels (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the neurotoxin 01 (U2-agtx) family.
CC       {ECO:0000305}.
