Alpha-Bungarotoxin

Alpha-Bungarotoxin

α-bungarotoxin is one of the components of the venom of the elapid snake Taiwanese banded krait ("Bungarus multicinctus"). It binds irreversibly and competitively to the acetylcholine receptor found at the neuromuscular junction, causing paralysis, respiratory failure and death in the victim.

α-bungarotoxin is also a selective antagonist of the α7 nicotinic acetylcholine receptor in the brain, and as such has applications in neuroscience research.

History

Bungarotoxin was discovered by Chuan-Chiung Chang and Chen-Yuan Lee of the National Taiwan University in 1963.
