Abstract

N. Zilberberg, E. Zlotkin and M. Gurevitz. The cDNA sequence of a depressant insect selective neurotoxin from the scorpion Buthotus judaicus. Toxicon 29, 1155-1158, 1991.-A 400 nucleotide cDNA clone encoding the depressant insect toxin of the scorpion Buthotus judaicus (BjIT2), was isolated. DNA sequence analysis suggests that the toxin is a processed product of a precursor composed of: (1) a 21 amino acid residue signal peptide; (2) a 61 amino acid region of the mature toxin; and (3) an additional Arg-Lys-Lys tail at the carboxy terminus prior to a termination codon. Comparison between the precursor polypeptides of BjIT2 and another depressant insect toxin derived from the scorpion Leiurus quinquestriatus hebraeus (LqhIT2) shows similarities in their hydropathic profiles.
