The deathstalker is one of the most dangerous species of scorpions. [10] [11] Its venom is a powerful mixture of neurotoxins, with a low lethal dose. [12] While a sting from this scorpion is extraordinarily painful, it normally would not kill a healthy adult human.
Alpha-Insect Toxin LqhαIT is a neurotoxic protein found in the venom of the Leiurus hebraeus, commonly known as the Hebrew deathstalker scorpion.It is classified as an alpha-toxin due to its effect on insect voltage-gated sodium channels, causing prolonged neuronal firing that leads to paralysis in affected insects.
The venom composition of the deathstalker scorpion contains neurotoxins which are almost completely responsible for this symptom. The poison from this scorpion contain 4 components: chlorotoxin, charybdotoxin, scyllatoxin, and agitoxins. Upon injection with the venom, sacral parasympathetic nerve are stimulated causing a change in the neuronal ...
The deathstalker's powerful venom contains the 36-amino acid peptide chlorotoxin (ribbon diagram shown). This blocks small-conductance chloride channels, immobilizing its prey. [113] Scorpion venom is a mixture of neurotoxins; most of these are peptides, chains of amino acids. [114]
Leiurus is a genus of scorpion of the family Buthidae. The most common species, L. quinquestriatus, is also known under the common name Deathstalker.

Of more than a thousand known species of scorpion, only a few dozen have venom that is dangerous to humans, [6] most notably the bark scorpions, including: Centruroides spp. Deathstalker (Leiurus quinquestriatus) Central and South American Tityus, include the Brazilian yellow scorpion. Androctonus spp. Parabuthus spp. Hottentotta spp.
Chlorotoxin is a 36-amino acid peptide found in the venom of the deathstalker scorpion (Leiurus quinquestriatus) which blocks small-conductance chloride channels. [2] The fact that chlorotoxin binds preferentially to glioma cells has allowed the development of methods for the treatment and diagnosis of several types of cancer.
