Toxins in the venom of only two South African scorpions P. transvaalicus and P. granulatus have been found to interact with Ca2+ channels. Function i. Alpha toxins bind voltage-independently at site-3 of sodium channels (Nav) and inhibit the inactivation of the activated channels, thereby blocking neuronal transmission. Urine retention. Second, their stinger and venom. Of the 22 Parabuthus species that occur in southern Africa, only two, namely P. granulatus and P. transvaalicus have been shown to be associated with serious envenomings. Stimulation of the autonomic nervous system through the release of endogenous catecholamines and acetylcholine, as observed following Mesobuthus (= Hottentotta), Leiurus and Tityus stings, is not as marked with Parabuthus stings.
