CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:17153339}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC       {ECO:0000269|PubMed:17153339}.
CC   -!- DOMAIN: The cysteine framework is III (CC-C-C-CC). Classified in the M-
CC       3 branch, since 3 residues stand between the fourth and the fifth
CC       cysteine residues. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the conotoxin M superfamily. {ECO:0000305}.
