Stichodactyla helianthus Neurotoxin, a toxin originally isolated from sea anemone Stichodactyla helianthus, inhibits the specific binding of dendrotoxin I to rat brain membranes. Because of its unique structure (containing three intramolecular disulfide bridges) and high affinity for some potassium channels, it may be a useful molecular probe for studying potassium channels.
