Toehold switch for hsa-miR-15b-5p

Toehold switches are synthetic riboregulators that regulate gene expression post-transcriptionally. Gene expression can be activated in the presence of a cognate single stranded RNA molecule that contains an arbitrary sequence (the trigger RNA). The trigger RNA binds to the switch through base pairing, causing a conformational change that activates translation of the downstream protein coding region.

This part codes for a toehold switch that contains a region that is complementary to the micro-RNA hsa-mir-15b-5p (the trigger RNA). In the presence of hsa-mir-15b-5p, translation of the downstream protein coding region occurs.

This part can be used to regulate the expression of any protein in response to the levels of hsa-mir-15b-5p present in a system.

We believe that the transcripts produced by this part are toxic when expressed at reasonably high concentrations in E.coli (e.g. the concentrations produced from the BBa_J23111 constitutive promoter).

N.B. This part contains a strong RBS sequence.
