| + | [[http://www.uniprot.org/uniprot/CXDA_CONTE CXDA_CONTE]] Delta-conotoxins bind to site 6 of voltage-gated sodium channels (Nav) and inhibit the inactivation process. Binding of this toxin is strongly calcium-dependent but not voltage-dependent. The binding site is most likely on the extracellular side of the sodium channel. Binds receptor sites on both mollusk and rat central nervous system, but despite its high affinity binding to rat sodium channel, it has no functional effect in vivo and in vitro on it. Has also no effect on Gambusia fish. Is important in mollusk for the paralysis of the prey. Upon injection of the peptide, a subordinate lobster assumes an exaggerated dominant posture (of a 'King-Kong' lobster!). | ||
