Birtoxin
Birtoxin
Birtoxin (pronounced: /bɪrˈtɒksɪn/) is a potent neurotoxic polypeptide found in the venom of the Parabuthus transvaalicus, a species of scorpion native to southern Africa.
Etymology
The term "Birtoxin" is derived from the Latin birtus, meaning "scorpion", and the Greek toxikon, meaning "poison".
Description
Birtoxin is a type of scorpion venom that specifically affects the nervous system. It is a neurotoxin that blocks voltage-gated sodium channels, causing an influx of sodium ions into the neuron. This results in the overexcitation of the neuron, leading to symptoms such as paralysis, convulsions, and in severe cases, death.
