Previous studies in our laboratory have shown that CryIC, a lepidopteran-specific toxin from Bacillus thuringiensis, triggers calcium and chloride channel activity in SF-9 cells (Spodoptera frugiperda, fall armyworm). Chloride currents were also observed in SF-9 membrane patches upon addition of CryIC toxin to the cytoplasmic side of the membrane. In the present study the ability of activated CryIC toxin to form channels was investigated in a receptor-free, artificial phospholipid membrane… CONTINUE READING
