MeSH definition : Neurotoxic proteins from the venom of the banded or Formosan krait (Bungarus multicinctus,
an elapid snake). alpha-Bungarotoxin blocks nicotinic acetylcholine receptors and
has been used to isolate and study them; beta- and gamma-bungarotoxins act presynaptically
causing acetylcholine release and depletion. Both alpha and beta forms have been characterized,
the alpha being similar to the large, long or Type II neurotoxins from other elapid
venoms.;
