It is evident from the data reviewed that scorpion toxins can be distinguished on the basis of three properties: their effects on Na currents, their specific binding to excitable membranes, and the effects of depolarization and pH on binding and on effect. Additional work with other scorpion toxins is required to establish the degree of correlation between the three properties for each class of toxin. Further investigations with this family of homologous proteins will undoubtedly contribute not only to our understanding of the toxins themselves but also to our understanding of the structure and function of the Na channel.
