Abstract
Potassium channel-specific scorpion toxins (KTx) are usually small, basic peptides made up of 23-43 amino acids stabilized by 3-4 disulfide bonds. KTx are classified into 6 subfamilies. The Ts16 toxin, isolated from the scorpion Tityus serrulatus, was partially characterized in 2011, demonstrating selectivity for potassium channels of the Kv1 subtype.2. In the same year, another study su…
