Abstract
A conditional allelic system is provided where recombinant cells express a fusion protein, where the fusion protein comprises at least a functional portion of a target protein and a destabilizing peptide. The destabilizing peptide binds to a small stabilizing molecule that results in the stabilization of the fusion protein in a functional form, while in the absence of the small stabilizing molecule, the protein function is substantially reduced. The system finds use in studying cellular pathways, preparing transgenic animals that can develop in the presence of the small stabilizing molecule and can then be studied in the presence and absence of the fusion protein to determine the functions and/or effects of target protein function in and/or on various environments. Specifically, a mutated peptide from mTOR is employed as the destabilizing peptide and a modified rapamycin is employed as the small stabilizing molecule.
