Expressed by the venom duct. The cysteine framework is V (CC-CC). Contains 2 disulfide bonds that can be either 'C1-C3, C2-C4' or 'C1-C4, C2-C3', since these disulfide connectivities have been observed for conotoxins with cysteine framework V (for examples, see AC P0DQQ7 and AC P81755). Belongs to the conotoxin T superfamily.
