zp21_B Toehold Switch for miR-21 Detection

Introduction

zp21_B toehold switch is a regulatory part for the downstream reporter gene. With this part, the protein expression can be controlled by the miR-21. 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-21, 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.
