scorpion venom toxicity is of major concern due to its influence on human activities and public health. we investigated the in-vitro process of cell death caused by two iranian scorpions odontobuthus doriae and bothutus salceyi venom on human cell lines. the aim of this study was to provide further information about triggering cell death and suggestion of methods for the elimination of unwanted...

In this study, the cDNA of a new peptide from the venom of the scorpion, Buthotus saulcyi, was cloned and sequenced. It codes for a 64 residues peptide (Bsaul1) which shares high sequence similarity with depressant insect toxins of scorpions. The differences between them mainly appear in the loop1 which connects the beta-strand1 to the alpha-helix and seems to be functionally important in long ...
