Meaning and Definition
A neurotoxic phospholipase A2 complex derived from the venom of the South American rattlesnake, Crotalus durissus terrificus, which blocks neuromuscular transmission.
In biochemistry and toxicology, crotoxin serves as a model protein complex for studying neurotoxicity, presynaptic inhibition, and phospholipase activity. It is also investigated for potential therapeutic applications in pain management and cancer treatment due to its selective toxicity.

FAQ
Frequently Asked Questions
No, crotoxin is specific to the South American rattlesnake species Crotalus durissus terrificus and a few closely related subspecies.
It is being researched for potential therapeutic applications, such as in pain management and cancer treatment, due to its specific mechanism of action, but it is not a licensed medicine.
It is a type of enzyme that breaks down phospholipids, which are key components of cell membranes. This activity is central to crotoxin's toxic effect.
In British English: /ˈkrəʊtɒksɪn/ (KROH-tok-sin). In American English: /ˈkroʊtɑːksɪn/ (KROH-tahk-sin). The stress is on the first syllable.
A neurotoxic phospholipase A2 complex derived from the venom of the South American rattlesnake, Crotalus durissus terrificus, which blocks neuromuscular transmission.
Crotoxin is usually technical/scientific in register.
