Margatoxin TFA, an alpha-KTx scorpion toxin isolated from Centruroides margaritatus venom, is a 39-amino-acid peptide that serves as a high-affinity inhibitor of Kv1.3 (Kd = 11.7 pM). It also inhibits Kv1.2 (Kd = 6.4 pM) and Kv1.1 (Kd = 4.2 nM), making it a valuable tool for ion channel research [1] [2].
