μ-Conotoxin PIIIA(u-芋螺毒素 PIIIA)  

Blocker of Na_v1.4 channels

钠离子通道Na_v1.4阻断剂

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  Na_v1.4  (IC₅₀ ~ 44 nM) than for the CNS Na_v1.2 subtype (IC₅₀~ 640 nm). μ-Conotoxin PIIIA  blocks  more  irreversibly amphibian  muscle  sodium  channels  than mammalian ones.
