Molecular approaches for structural characterization of a new potassium channel blocker from Tityus stigmurus venom: cDNA cloning, homology modeling, dynamic simulations and docking

► Successful cloning of a potassium channel blocker from T. stigmurus scorpion. ► A new β-KTx peptide from T. stigmurus. ► Three-dimensional structure and phylogenetic analysis. ► Dynamic simulations and molecular protein-protein docking.
