Deskripsi
Genetic circuits that control transgene expression in response to pre-defined transcriptional cues would enable the development of smart therapeutics. Here the authors engineer programmable RNA sensors, DART VADARs, in which ADARs autocatalytically convert target hybridization into a translational output, thus amplifying editing by endogenous ADAR via positive feedback and conferring high dynamic range and a small genetic footprint.
