The cysteine arrangements are the same for omega, delta and kappa families, even though omega conotoxins are calcium channel blockers, whereas delta conotoxins delay the inactivation of sodium channels, and kappa conotoxins are potassium channel blockers.
As disposicióins das cisteínas son as mesmas nas familias omega, delta e kappa, a pesar de que as omega-conotoxinas son bloqueadoras dos canais de calcio, mentres que as delta-conotoxinas atrasan a activación dos canais de sodio, e as conotoxinas kappa son bloqueadoras dos canais de potasio.
