The GPX2 gene encodes a homologue of mammalian phospholipid hydroperoxide glutathione peroxidase in Saccharomyces cerevisiae . Previously, we have reported that the oxidative stress‐induced expression of GPX2 is strictly regulated by Yap1 and Skn7 transcription factors. Here, we found that the expression of GPX2 is induced by CaCl 2 in a calcineurin (CN)/Crz1‐dependent manner, and the CN‐dependent response element was specified in the GPX2 promoter. Neither Yap1 nor Skn7 was required for Ca 2+ ‐dependent induction of GPX2 , therefore, distinct regulation for the oxidative stress response and Ca 2+ signal response for GPX2 exists in yeast cells.
