Application

Charybdotoxin has been used:in the inhibition of endothelium-derived hyperpolarizing factor responsesin electrophysiological studies, as calcium channel blockersas a transport inhibitor

Biochem/physiol Actions

High (BK) or intermediate (IK1) conductance calcium-activated and voltage-gated (Kv1.3) channel blocker.

Potent and selective inhibitor of the Ca²⁺-activated K⁺ channel present in GH₃ anterior pituitary cells and primary bovine aortic smooth muscle cells.

Charybdotoxin (ChTX) is a scorpion venom, which blocks a voltage-gated potassium channel, by binding to the extracellular loop of the potassium channel.

Other Notes

Peptide found in the venom of the scorpion Leiurus quinquestriatus.
