CC   -!- FUNCTION: Omega-conotoxins act at presynaptic membranes, they bind and
CC       block voltage-gated calcium channels (Cav). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:22705119}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct. {ECO:0000305}.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin.
CC       {ECO:0000250|UniProtKB:P05484}.
CC   -!- DOMAIN: The cysteine framework is VI/VII (C-C-CC-C-C).
CC   -!- MASS SPECTROMETRY: [Omega-conotoxin-like CnVIIF]: Mass=2653.96;
CC       Method=Electrospray; Note=CnVIIF.;
CC       Evidence={ECO:0000269|PubMed:22705119};
CC   -!- MASS SPECTROMETRY: [Omega-conotoxin-like CnVIID]: Mass=2595.99;
CC       Method=Electrospray; Note=CnVIID.;
CC       Evidence={ECO:0000269|PubMed:22705119};
CC   -!- MISCELLANEOUS: Found in injectable (milked) (IV) venom.
CC       {ECO:0000305|PubMed:22705119}.
CC   -!- SIMILARITY: Belongs to the conotoxin M superfamily. {ECO:0000305}.
