CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:10521453}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC       {ECO:0000305|PubMed:10521453}.
CC   -!- DOMAIN: The cysteine framework is V (CC-CC). {ECO:0000305}.
CC   -!- PTM: Contains 2 disulfide bonds that can be either 'C1-C3, C2-C4' or
CC       'C1-C4, C2-C3', since these disulfide connectivities have been observed
CC       for conotoxins with cysteine framework V (for examples, see AC P0DQQ7
CC       and AC P81755). {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the conotoxin T superfamily. {ECO:0000305}.
