μ Conotoxin PIIIA, Blocker of Nav1.4 channels
μ-Conotoxin PIIIA (mu-conotoxin PIIIA) has been isolated from the venom of the cone Conus purpurascens. μ-conotoxin PIIIA demonstrates a higher affinity for the mammalian muscle sodium channel Nav1.4 (IC50 ~ 44 nM) than for the CNS Nav1.2 subtype (IC50 ~ 640 nm). μ-Conotoxin PIIIA blocks more irreversibly amphibian muscle sodium channels than mammalian ones.
