ShK toxin blocks voltage-dependent potassium channel (Kv1.3 channel). ShK toxin can be isolated from the whole body extract of the Caribbean sea anemone (Stichodactylu helianthus). ShK toxin competes with dendrotoxin I and α-dendrotoxin for binding to synaptosomal membranes of rat brain, facilitates acetylcholine release. ShK toxin suppresses K+ currents in cultured rat dorsal root ganglion neurons. ShK toxin also inhibits T lymphocyte proliferation.
