Taking into consideration that the Kv1.2, Kv1.3, and Kv1.6 subtypes are the main targets of most conotoxins and conopeptides (Table 2), it is reasonable to assume that they could be involved during the capture or defense behaviors in organisms in their natural habitats and, even more importantly, that a possible usefulness could be assumed in the study of some conditions in which these subtypes are related, such as the case of Parkinson’s disease, where it has been reported that they are involved in the progress of said disease [74]. This evidence concerns the gene KCNA2 and Parkinson disease.
