CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC structurally defines this protein as a knottin. {ECO:0000250}.
CC -!- DOMAIN: The cysteine framework is VI/VII (C-C-CC-C-C).
CC -!- SIMILARITY: Belongs to the conotoxin O1 superfamily. {ECO:0000305}.
