Toehold switch is a secondary structure of RNA. Because of special sequence design, it can form a hairpin structure and hide ribosome binding site (RBS)in the loop. There are three basic elements of toehold switches including 30bp trigger sequence(AAATAAATTGAAGTGGGCTCAAGGAGACCC), bacteria ribosome binding site and linker.The trigger sequence of this part is complementary to a part of Dual specificity protein phosphatase 1 (DUSP1) mRNA(DUSP1 partial sequence, BBa_K1728006). Once the DUSP1 mRNA is presented, the toehold structure will open. Therefore, the ribosome is able to bind on the RBS and translate the down stream gene.
