beta-Dendrotoxin (beta-DTX), a polypeptide component of Eastern Green Mamba snake venom, inhibits a slow voltage-activated 86Rb efflux from synaptosomes, suggesting that beta-DTX inhibits K+ channels. The effects of beta-DTX on the K+ currents in primary cultured and subcultured (passages 8-12)

Venom from the green mamba (Dendroaspis angusticeps) blocked 86Rb efflux through voltage-gated K channels in rat brain synaptosomes. Crude venom inhibited both rapidly inactivating, 4-aminopyridine-sensitive K channels, and noninactivating, phencyclidine-sensitive, K channels.
