Abstract

Methods and compositions for the rapid and reversible destabilizing of specific proteins using cell-permeable, synthetic molecules are described. Stability-affecting proteins, e.g., derived from FKBP and DHFR proteins are fused to a protein of interest and the presence or absence of the ligand is used to modulate the stability of the fusion protein.
