Translatable PP7 stem-loops were generated by gene synthesis (Genscript) removing potential stop codons in all three reading frames. The 405 nucleotide stem-loop cassette contained six copies of the PP7 stem-loops and were optimally positioned 40 nucleotides apart to prevent ribosomes stalling at adjacent stem-loops. The PP7 stem-loops were also codon optimized (tRNA abundance and coding potential) and RNA-folding (mfold). The 6x PP7stem-loop cassette was multimerized using SalI and XhoI to generate a cassette with 12 copies of the PP7 stem-loops.
The PP7 stem-loop cassette cloned into a modified version of the pmaxGFP plasmid (Lonza), which contains the CMV immediate early promoter for expression and the β-globin-IgG chimeric intron in the 5′ UTR. The GFP sequence was replaced by NLS-3xHA tagged dNP799 (a fluoregen activating protein). The PP7 stem-loop cassette was fused in-frame to the C-terminus of dNP799. The 24x MS2 stem-loop cassette was cloned downstream of the stop codon of the pp7 stem-loop cassette.
The CMV promoter was replaced by 45 copies of the E/GRE recognition elements (ponA-45) to induce expression of the reporter mRNA in the presence of ponasterone A. The E/GRE elements are bound by a heterodimer of retinoid-X-receptor (RXR) and a synthetic ecodysone receptor (VgEcR).
The final construct contains the following features: ponA-45 - chimeric intron – NLS - 3xHA – dNP799 – 12x PP7 stem-loops – stop codon – 24x MS2 stem-loops – SV40 polyA. See publication for more details.
