This family consists of ergtoxin peptides which are toxins secreted by the scorpions. The ergtoxins are capable of blocking the function of K+ channels. More than 100 ergtoxins have been found from scorpion venoms and they have been classified into three subfamilies according to their primary structures [1].	Domain
