Specific labeling of proteins within living cells with single residue precision through genetically encoded click chemistry
The development of catalyst-free click chemistry, i.e. a chemical reaction that is non-toxic and proceeds readily and specifically even within living organisms, has revolutionized chemical biology. By encoding strained alkyne unnatural amino acids into the genetic repertoire of the cell, we exploited this chemistry to label proteins with single residue specificity in bacteria. Meanwhile, we extended the method to more click type reactions, creating a unique opportunity to establish these techniques for installing probes to control and visualize protein function within living species.
In this proposal, we aim to lay the foundation for a smaller and more stable substitute to fluorescent proteins in biology, medicine, and diagnostics. In particular, we aim to explore the potential of click chemistries of the Huisgen-type and inverse electron-demand Diels-Alder reaction and optimize and characterize probes in vitro and in vivo. We will use the techniques to study growth factor receptor signaling and to develop genetically encoded small molecule dye FRET sensors
