ShK toxin is a potent inhibitor of the voltage-dependent potassium channel (Kv1.3), derived from the Caribbean sea anemone Stichodactylus helianthus. This toxin competitively interacts with dendrotoxin I and α-dendrotoxin at synaptosomal membranes, enhancing acetylcholine release. In addition to its neural effects, ShK toxin effectively suppresses K+ currents in cultured rat dorsal root ganglion neurons and demonstrates significant inhibition of T lymphocyte proliferation. It serves as a valuable tool in studies of neurophysiology and immunology.
