Na+ Channel (Especially Nav1.7) / Ca2+ Channel Blocker (Gating Modifier) ProTx-II was originally isolated from the venom of the tarantula Thrixopelma pruriens. Potent channel blocker with high selectivity for Nav1.7 channel. ProTx-II is a potent inhibitor for tetrodotoxin-sensitive and tetrodotoxin-resistant voltage-gated sodium channels. The Nav1 type channels exists in different sub types and ProTx-II shows a special affinity to the Nav1.7 channel which is responsible for pain processing.
