摘要：

The photo-regulation of transgene expression is one effective approach in mammalian synthetic biology due to its high spatial and temporal resolution. While DNAs are mainly used as vectors, modified RNAs (modRNAs) are also useful for medical applications of synthetic biology, because they can avoid insertional mutagenesis and immunogenicity. However, the optogenetic control of modRNA-delivered transgenes is much more difficult than that of DNA-delivered transgenes. Here, we develop two types of photo-controllable translational activation systems that are compatible with modRNAs. One is composed of a heterodimerization domain-fused split translational activator protein and a photocaged heterodimerizer. The other is composed of a destabilizing domain-fused translational activator protein and a photocaged stabilizer. The destabilized type can be used for not only translational activation but also translational repression of the modRNAs. These photo-controllable translation systems will expand the application of mammalian synthetic biology research.
