Κ-Bungarotoxin
κ-Bungarotoxin
Protein neurotoxin of the bungarotoxin family
κ-Bungarotoxin (often written κ-Bgt; historically also called toxin F[2]) is a protein neurotoxin of the bungarotoxin family that is found in the venom of the many-banded krait, a snake found in Taiwan. κ-Bungarotoxin is a high affinity antagonist of nicotinic acetylcholine receptors (nAChRs), particularly of CHRNA3; it causes a post-synaptic blockade of neurotransmission. Although there is significant variability in the clinical effects of snake bites, neuromuscular paralysis and respiratory failure are associated with krait bites.[3]
