Conditional protein degradation in Yarrowia lipolytica using the auxin-inducible degron.

ABSTRACT: Conditional protein degradation is a powerful tool for controlled protein knockdown. The auxin-inducible degron (AID) technology uses a plant auxin to induce depletion of degron-tagged proteins, and it has been shown to be functional in several non-plant eukaryotes. In this study, we demonstrated AID-based protein knockdown in an industrially important oleaginous yeast Yarrowia lipolytica. Using the mini-IAA7 (mIAA7) degron derived from Arabidopsis IAA7, coupled with an Oryza sativa TIR1 (OsTIR1) plant auxin receptor F-box protein (expressed from the copper-inducible MT2 promoter), C-terminal degron-tagged superfolder GFP could be degraded in Yarrowia lipolytica upon addition of copper and the synthetic auxin 1-Naphthaleneacetic acid (NAA). However, leaky degrad
