Auxin-Inducible Degron System for Depletion of Proteins in Saccharomyces cerevisiae.

ABSTRACT

The auxin-inducible degron (AID) is a powerful tool that is used for depletion of proteins to study their function in vivo. This method can conditionally induce the degradation of any protein by the proteasome simply by the addition of the plant hormone auxin. This approach is particularly valuable to study the function of essential proteins. The protocols provided here describe the steps to construct the necessary strains and to optimize auxin-inducible depletion in Saccharomyces cerevisiae. © 2019 by John Wiley & Sons, Inc.
