In this work, the authors report a sophisticated combination of genetic, biophysical, and biochemical analyses to identifies the cycling conformational states of PPM1D. The findings reveal how an allosteric inhibitor locks the protein into a conformationally inactive state, and explain the distribution of PPM1D activating mutations in cancer.
