Toehold switch is composed of cis-acting element RNA hairpins and trans-acting factor trigger RNA. The binding of a trigger RNA to the toehold sequence allows for a branch migration process, exposing AUG and RBS for translation initiation.

Applications of BBa_K3328008

Compared with the blank control (IPTG=0 M, aTc=0 mg/mL), the fluorescence of GFP was low when only the promoter before toehold sequence was turned on (IPTG=0.1 M, aTc=0 mg/mL). This indicates that the toehold has the advantage of low leakage. When the trigger was expressed (IPTG=0.1 M, aTc=0.25 mg/mL), it showed a high GFP fluorescence of up to 32-fold due to the destruction of toehold hairpin structure. Error bar: SD (n=9).
