Abstract


We have generated a collection of yeast strains, each of which has an essential yeast gene under the control of the tetracycline-responsive, tetO, promoter. Screens using first-generation promoter-swap strains uncovered the non-specific responsiveness of the tetO7 promoter to a known human transcription factor (hIRF-1). Non-specific regulation was not observed with the tetO2 promoter. Reporter assays have been used to demonstrate this phenomenon. Subsequent efforts to generate a collection of tetracycline-regulatable strains have focused on the tetO2 promoter. These strains are available to the yeast community and can be used for functional genomics studies.
