Leiurotoxin-1 Dab7 - Ion Channels and Transporters
Leiuorotoxin-Dab7 (Lei-Dab7) is a mutated version of Leiurotoxin, a peptide identified from the venom of the scorpion Leiurus quinquestriatus hebraeus. The Dab amino acid in position 7 confers to this compound a high selectivity for SK2 channels among other channels. Lei-Dab7 exhibits > 200 fold selectivity for SK2 over SK1, SK3, IK, Kv and Kir channels. The IC50 for SK2 is about 3 nM.
