Engineered fusion proteins comprising a self-excising degron for controlling protein production are disclosed. In particular, the inventors have constructed fusion proteins comprising a degron connected to a protein of interest through a cleavable linker comprising a hepatitis C virus (HCV) protease site. The degron can be removed from the protein of interest by a czs-encoded HCV protease such that the protein of interest can be produced with minimal structural modification. Clinically available HCV protease inhibitors can be used to block protease cleavage such that the degron is retained after inhibitor addition on subsequently synthesized protein copies. The degron when attached causes rapid degradation of the linked protein. Such fusions of a degron to a protein of interest will be especially useful when control over protein production with minimal structural modification is desired.
