CC   -!- FUNCTION: Probable neurotoxin. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:30791616}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC       {ECO:0000305|PubMed:30791616}.
CC   -!- DOMAIN: The cysteine framework is VI/VII (C-C-CC-C-C). {ECO:0000305}.
