SJTU-BioX-Shanghai iGEM team is designing a set of Codon-Switches that regulate target protein biosynthesis (translation). In our Rare-Codon Switch, the translation of the protein can be finely turned up/down with the control of rare tRNA amount, aaRS that charges the rare tRNA and rare codons. Besides, our device can be made into switches that can be turned on/off without background noise in two ways. One is to use stop codon as the controlling element, the Stop-Codon Switch. The other is to use any codon but the original start codon to initiate translation, the Initial-Codon Switch. Our design has expanded the regulating tools for synthetic biology and introduced brand-new methods for protein function analysis.
