ATX-II. Voltage-gated Na+ Channel Modulator
ATX-II is a 47 amino acid peptidyl toxin, originally isolated from Anemonia sulcata sea anemone venom. It is a potent neurotoxin, which modulates voltage-gated Na+ channel gating kinetics by delaying its inactivation and prolonging the action potential of excitable membranes.
ATX-II has been used as a powerful activator of TTX-sensitive and insensitive Na+ channels in various excitable tissue and cell types (at concentration range of 10-100nM).
