Iberiotoxin 伊比(利亞)蝎毒素 

Blocker of high conductance Ca²⁺-activated K⁺ channel

高電導鈣激活鉀離子通道阻斷劑

Iberiotoxin (IbTx) is a toxin that was originally isolated from Buthus tamulus scorpion venom. Iberiotoxin inhibits selectively the high conductance Ca²⁺-activated K⁺ channel (K_Ca1.1) at nanomolar concentrations (IC₅₀ ~2 nM). This toxin does not affect other types of calcium-dependent or voltage-dependent K⁺ channels. Iberiotoxin is a valuable tool to study specifically Maxi-K channels.
