TTX

[(Science: protein) A potent neurotoxin (319 D) from the Japanese puffer fish. It binds to the sodium channel, blocking the passage of action potentials. Its activity closely resembles that of saxitoxin.

[1. A potent neurotoxin found in the liver and ovaries of the Japanese pufferfish, Sphoeroides rubripes, other species of pufferfish, and some newts; produces axonal blocks of the preganglionic cholinergic fibers and the somatic motor nerves. Tetrodotoxin blocks voltage-gated Na+ channels in excitable tissues.
