[KAX31_ANDMA] Potent inhibitor of large conductance calcium-activated potassium channels (BK-Ca). Also binds to the dendrotoxin sensitive voltage-dependent potassium channel. It appears to block channel activity by a simple bimolecular inhibition process. Induces a transient period of fast flickering in the channel openings, followed by an almost complete blockade of the channel. Its binding affinity to rat brain synaptosomes is 5-fold higher than this of KTX-3. Binding of the toxin to the channel is associated with significant structural rearrangements in both molecules.
