Comment: From the venom gland of Mesobuthus tamulus (Eastern Indian scorpion). Iberiotoxin is selective for KCa1.1 channels that associate with β1, β2 and β3 regulatory subunits [1-3]. In contrast the KCa1.1 channels containing the β4 subunit that are found predominantly in the central nervous system are resistant to iberiotoxin inhibition [6]
