INTRODUCTIONThis assay is performed to detect ubiquitylated proteins in yeast. Yeast that have been transformed with a vector expressing polyhistidine-tagged ubiquitin (Ub) under the control of a copper-inducible promoter are grown, induced with copper, and harvested. Total ubiquitylated proteins are then recovered by nickel-affinity chromatography, and specific proteins are detected by Western blotting.
