When different cone snail peptides are injected into the CNS of vertebrates
, they elicit diverse behaviors primarily because of their selectivity for
specific receptor or ion channel subtypes. The subcellular context of the h
ighly localized targets (i,e, the presence of other cellular elements that
are functionally linked to the targets of conopeptides) is another determin
ant of the elicited behavior, Recent studies have advanced our understandin
g of the mechanisms by which four conopeptides produce different behaviors
in mice.
