RT   transcriptome.";
RL   BMC Genomics 12:60-60(2011).
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC   -!- DOMAIN: The cysteine framework is IV (CC-C-C-C-C).
CC   -!- PTM: Contains 3 disulfide bonds (By similarity). They are not indicated
CC       here, since framework IV presents two different connectivities (I-V,
CC       II-III, IV-VI and I-III, II-V, IV-VI). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the conotoxin A superfamily. {ECO:0000305}.
