CC   -!- FUNCTION: Acts as a neurotoxin by inhibiting an ion channel (By
CC       similarity). May also act as a serine protease inhibitor, since it
CC       possess the kazal serine protease inhibitor signature. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC   -!- DOMAIN: The cysteine framework is IX (C-C-C-C-C-C).
CC   -!- SIMILARITY: Belongs to the conopeptide P-like superfamily.
CC       {ECO:0000305}.
