      DescriptionRecombinant Buthus tamulus iberiotoxin expressed in E. coli. A single polypeptide chain of 37 amino acids that displays about 68% sequence homology with charybdotoxin (ChTx). Acts as a selective, reversible blocker of high conductance, Ca2+-activated K+ channels (PK,Ca). rIbTx does not block other types of voltage-dependent ion channels, especially other types of K+ channels that are sensitive to inhibition by ChTx. Shown to block PK,Ca in excised membrane patches from bovine aortic smooth muscle, acting exclusively at the outer face of the channel (IC50 = 250 pM). Causes a decrease in probability of channel opening and the channel open mean time. rIbTx appears to modulate ChTx binding by an allosteric mechanism.
