Chi-conotoxin is a family of Cone snail venom chi-conopeptide class bioactive peptides based. These conopeptides show a unique ability, highly selectively and non-competitively, to inhibit the noradrenaline transporter. They show an unusual cysteine-stabilised scaffold that presents a gamma-turn in an optimised conformation for high affinity interactions with the noradrenaline transporter [1].	Domain
