This toehold switch has been designed to open up its hairpin loop structure upon binding with miRNA-21, resulting in the translation of downstream reporter protein. The design of toehold switch can be separated into the following 5 regions from its 5' end: trigger binding sites, stem region, loop region with RBS, complimentary stem region with start codon, and linker amino acids. In our constructions of toehold switches for miRNA-21, we optimised the region of loop with RBS and linker amino acids based on three articles: the original work on toehold switch (Green, A.A. et al., 2014), the adaptation of toehold switch to detect zika virus (Pardee, K. et al., 2016), and novel toehold switch design for detection of miRNA in mammalian cells (Wang, S. et al., 2019) . We chose to test the 3 different loop structures and 2 different linker structures (Pardee, K. et al. and Wang, S. et al.) from the above-mentioned studies.

zp21_B Toehold Switch for miR-21 Detection

This toehold switch has been designed to open up its hairpin loop structure upon binding with miRNA-21, resulting in the translation of downstream reporter protein. The design of toehold switch can be separated into the following 5 regions from its 5' end: trigger binding sites, stem region, loop region with RBS, complimentary stem region with start codon, and linker amino acids. In our constructions of toehold switches for miRNA-21, we optimised the region of loop with RBS and linker amino acids based on three articles: the original work on toehold switch (Green, A.A. et al., 2014), the adaptation of toehold switch to detect zika virus (Pardee, K. et al., 2016), and novel toehold switch design for detection of miRNA in mammalian cells (Wang, S. et al., 2019) . We chose to test the 3 different loop structures and 2 different linker structures (Pardee, K. et al. and Wang, S. et al.) from the above-mentioned studies.
