zr31 Toehold Switch for miR-31 Detection
Description
zr31 toehold switch is a regulatory part for the downstream reporter gene. With this part, the protein expression can be controlled by the miR-31. The sequence of the toehold switch can be separated into the following 5 regions from its 5' end: TBS (trigger binding site), stem region, loop region with RBS (ribosome binding site), complimentary stem region with a start codon, and linker. Upon binding with miR-31, its hairpin structure can be opened up and the ribosomes can bind with its RBS (ribosome binding site), triggering the translation of the downstream reporter.
Design
The design of the toehold switch was mainly based on the previous research.1 2 3 4 5 6 For the zr31 toehold switch, we adopted the loop and linker structure from Green et al., 20167, and the linker structure is the random linker design by iGEM_CSMU_2020. Using NUPACK analysis and Vienna binding models, we designed the sequence of the toehold switch. (See our model page: [https://2020.igem.org/Team:CSMU_Taiwan/Model] )
