CC   -!- FUNCTION: Probable neurotoxin with unknown target. Possibly targets ion
CC       channels. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:21172372}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC       {ECO:0000305|PubMed:21172372}.
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}.
