The present invention relates to an orthogonal gene switch for regulating the expression of a desired gene. The gene switch comprises a chimeric transcription factor that does not respond to endogenous ligands, and a ligand that is capable of activating the chimeric transcription factor but not endogenous transcription factors. The present invention also relates to the method of constructing the orthogonal gene switch.
