A General Chemical Method to Regulate Protein Stability in the Mammalian Central Nervous System
(2010) In Chemistry and Biology 17(9). p.981-988- Abstract
- The ability to make specific perturbations to biological molecules in a cell or organism is a central experimental strategy in modern research biology. We have developed a general technique in which the stability of a specific protein is regulated by a cell-permeable small molecule. Mutants of the Escherichia coil dihydrofolate reductase (ecDHFR) were engineered to be degraded, and, when this destabilizing domain is fused to a protein of interest, its instability is conferred to the fused protein resulting in rapid degradation of the entire fusion protein. A small-molecule ligand trimethoprim (TMP) stabilizes the destabilizing domain in a rapid, reversible, and dose-dependent manner, and protein levels in the absence of TMP are barely... (More)

The ability of TMP to cross the blood-brain barrier enables the tunable regulation of proteins expressed in the mammalian central nervous system. (Less)
