CC   -!- FUNCTION: Gamma-conotoxins may act on voltage-gated non-specific cation
CC       pacemaker channels (HCN). {ECO:0000250}.
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 O2 superfamily. {ECO:0000305}.
