Research Interest

RNA aptamers are known to discriminate molecules in a highly sensitive way. One classic example is that the theophylline aptamer does not respond to caffeine though there is mere difference of one methyl group in structure. This superior sensitivity of aptamers distinguishing molecules is a nice characteristic to be incorporated in a synthetic biological regulatory network, which usually consists of many structurally similar metabolites. However, the application of using aptamers in a synthetic pathway has been severely limited by the ability to generate functional aptamers in vivo effectively. Traditional in vitro SELEX usually takes weeks in selection and characterization of aptamers and requires further screening for in vivo activities. In the Smolke lab, we have developed several portable, modular, and tunable engineered RNA-based switch platform that can adapt to different conformations upon binding of various molecular inputs and subsequently modulates the level of target gene expression. We can then use the existing sensor domain of these switch platforms developed from SELEX and implement it as a selection tool to screen library in order to generate aptamers for other structurally similar molecules. The eventual goal is to incorporate these platforms as part of the regulatory network in a synthetic biological pathway and redirect molecular fluxes to accumulate medicinal valuable intermediates that are too costly to be synthesized chemically.
