Toehold switch sensors
Webb12 apr. 2024 · Toehold switches are rationally designed post-transcriptional riboregulators placed in the 5′ untranslated region of mRNA molecules. In the inactive state of a toehold switch, the ribosome-binding site is inaccessible to the ribosome. In the presence of a trigger RNA molecule, protein production is turned on. Webb7 okt. 2024 · The authors of the first paper decided to analyze toehold switches not as sequences of bases, but rather as two-dimensional “images” of base-pair possibilities. …

They have been shown very useful in detecting a variety of targets including RNAs from Zika and Ebola viruses.
