Peptide toxin (37 residues) from the scorpion Leiurus quinquestriatus var hebraeus that is selective for the high-conductance calcium-activated K+ channel. Similar (and highly homologous in sequence) to charybdotoxin but more selective.


Iberiotoxin (IbTX) is an ion channel toxin purified from the Eastern Indian red scorpion Buthus tamulus. Iberiotoxin selectively inhibits the current through large-conductance calcium-activated potassium channels. == Chemistry == Iberiotoxin is a 37-amino acid peptide. The formula is C179H274N50O55S7. It is also known as `Potassium channel toxin ....
