| Research Abstract |
We previously identified ant bioactive peptides from a species of the Japanese ant Strumigenys kumadori, and termed these peptides SKTX1, 2, and 3.In this study, we constructed a cDNA library encoding various SKTX peptide derivatives on T7 phage. From the library, we screened the SKTX derivatives which specifically bind to rNa_v 1.3 channel using the binding ability to E3 domain of the channel. We selected 5 derivatives and the derivatives were recombinantly expressed by E. coli. We confirmed the binding ability of these derivatives by BIA core and the estimated binding ability of the derivatives were micro molar levels.
