Model of the cellular response to cadmium stress. Cadmium blocks Met4 ubiquitination, which leads to Met4 activation. Active Met4 induces glutathione synthesis, biosynthesis of sulfur amino acids, and a cell cycle arrest. Cadmium also activates the cell cycle checkpoint kinase Rad53 as well as a so far unidentified cell cycle arrest pathway.
