ABSTRACT:
The invention provides a fusion protein including a reporter polypeptide, a linker polypeptide comprising a protease cleavage site, and a repressor polypeptide. The repressor polypeptide represses the activity of the reporter polypeptide by conferring a specific localization in a cell that reduces activity of the reporter activity until the cleavage site is cleaved. A method is also provided for identifying a protease that recognizes a specific protease cleavage site. The invention further provides a method of identifying a compound that activates a protease.
