RT   "Genes expressed in a turrid venom duct: divergence and similarity to
RT   conotoxins.";
RL   J. Mol. Evol. 62:247-256(2006).
CC   -!- FUNCTION: Acts as a neurotoxin by inhibiting an ion channel.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC   -!- DOMAIN: The cysteine framework is VI/VII (C-C-CC-C-C).
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin. {ECO:0000250}.
