NTX accounts for only about 1% of the scorpion venom. [7] NTX is one of the best-studied toxic peptides from scorpion venoms. [6] It was the second purified toxin obtained from the genus Centruroides after neurotoxin II [8] and the first short peptide from scorpion venom to be reported in the literature. [9]
Scorpion toxins are proteins found in the venom of scorpions.Their toxic effect may be mammal- or insect-specific and acts by binding with varying degrees of specificity to members of the Voltage-gated ion channel superfamily; specifically, voltage-gated sodium channels, voltage-gated potassium channels, [3] and Transient Receptor Potential (TRP) channels.

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.
The venom from Leiurus abdullahbayrami can be very toxic. The venom of this species is one of the most potent venoms of the Turkish scorpions, and it provokes severe symptoms in the victims. Proteins make up half of the dry weight of the crude venom. The venom in this species stimulates voltage-gated sodium and potassium channels. [11]
Charybdotoxin (ChTX) is a 37 amino acid neurotoxin from the venom of the scorpion Leiurus quinquestriatus hebraeus (deathstalker) that blocks calcium-activated potassium channels. [2] This blockade causes hyperexcitability of the nervous system. It is a close homologue of agitoxin and both toxins come from Leiurus quinquestriatus hebraeus.
