Crotoxin
Crotoxin (CTX) is the main toxic compound in the snake venom of the South American rattlesnake, "Crotalus durissus terrificus". Crotoxin is a heterodimeric beta-neurotoxin, composed of an acidic, non-toxic and non-enzymatic subunit (CA), and a basic, weakly toxic, phospholipase A2 protein (CB). 
This neurotoxin causes paralysis by both pre- and postsynaptic blocking of acetylcholine signalling.
