Abstract
This year, Jilin_China made a RNA-based thermosensor toolkit for users, include four different types, which are heat-inducible RNA-based thermosensors, heat-repressible RNA-based thermosensors, cold-inducible RNA-based thermosensors and cold-repressible RNA-based thermosensors. For each type of RNA-based thermosensors, we have added many different Biobrick parts to the parts registry. And we make each type of thermosensors into a part collection, allow users choose appropriate thermosensors from the collection.
Our part collection including heat-inducible RNA-based thermosensors collection, heat-repressible RNA-based thermosensors collection and cold-repressible RNA-based thermosensors collection.
In order to make it easier for users to select an appropriate RNA-based thermosensor, we also developed a search engine for our toolkit, you can click here to enter the search engine page.
The introduction of each type of part collection is as followed:
-
Heat-inducible RNA-based thermosensor collection
In this collection, we provide a total of 48 different RNA-based thermosensors, which can regulate the expression of genes with the changed temperature. When the temperature is lower than the melting temperature of the stem-loop, the SD sequence is sequestered and cannot be bind by the ribosome. When the temperature elevate until the stem-loop structure is open, the SD sequence is exposed and the translation begins. The RNA-based thermosensors we designed has been characterized and mathematically fitted to prove that they have different melting temperature, expression intensity and sensitivity. Users can choos the appropriate RNA-based thermosensors according to their own needs.

In order to make our RNA-based thermosensor toolkit more suitable for users' needs, we updated the toolkit to version 2.0. We added the RNase E-based heat-repressible RNA-based thermosensors, including 23 different thermosensors. The stem-loop structure of the thermosensor contains the recognition and cleavage site of RNase E. At the elevated temperature, the stem-loop structure is opened, and the mRNA will be degraded, which lead to the failure of translation.
Heat-repressible RNA-based thermosensor collection contain these parts:

To expand the melting temprerature range of the thermosenor, we have made a second upgrade to the toolkit. In toolkit 3.0, we added cold-repressible and cold inducible RNA thermosenor, and made 10 cold-repressible RNA-based thermosensors into a part collection.
Cold-repressible RNA-based thermosensor is based in the RNase III. The stem-loop structure of the thermosensor mRNA contains the recognition and cleavage site of RNase III. When the temperature is lower than the melting temperature, the RNase III will degrade mRNA.
