Pharmacological Comparison of Two Different Insect Models Using the Scorpion α-Like Toxin BmK M1 from Buthus martensii Karsch
Abstract:In this study, the effect of the scorpion a-like toxin BmK M1 was investigated on isolated DUM neurons from Locusta migratoria and compared with the effect on para/tipE voltage-gated Na+ channels (VGSC), cloned from Drosophila melanogaster. The two insects display different pharmacological properties regarding α-like toxins. Moreover, with the aid of the α-like toxin BmK M1 and 5 of its mutants, the importance of aromatic residues for the interaction of the toxin with the VGSC in L. migratoria and D. melanogaster, is shown.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
