Margatoxin is a peptidyl toxin originally isolated from the scorpion Centruroides margaritatus. It is a specific blocker of KV1.3 channels (IC50~30 pM), but it also blocks KV1.6 and a splice variant of the Drosophila Shaker channels with IC50 of 5 and 150 nM respectively. In Xenopus oocytes the toxin is less potent and inhibits expressed KV1.3 channels with an apparent IC50 of ~1 nM.
