Details

ShK-toxin, originally isolated from the sea anemone Stichodactyla helianthus, has been found to inhibit the specific binding of dendrotoxin I to rat brain membranes. Due to its unique structure (it contains three intramolecular disulfide bridges) and high affinity for some potassium channels, ShK-toxin may become a useful molecular probe for investigating potassium channels.
