Abstract
Small regulatory RNA is an active area of research with untapped possibilities for application in biotechnology. Such applications include convenient gene silencing and fine-tuning of synthetic biological circuits, which are currently cumbersome processes restricted to well studied bacteria. We have investigated a novel type of RNA regulation[1][2], where the inhibition caused by a small regulatory RNA is relieved by another RNA called trap-RNA. The system displays a large dynamic range and can uniquely target and repress any gene of interest providing unprecedented flexibility. We suspect that any level of repression is achievable by simply altering the sequences of the involved RNAs. Multiple such systems can coexist without interfering and are, thus, compatible with more complex designs.
