Novel function of glutathione transferase in rat liver mitochondrial membrane: role for cytochrome c release from mitochondria.

Microsomal glutathione transferase (MGST1) is activated by oxidative stress. Although MGST1 is found in mitochondrial membranes (mtMGST1), there is no information about the oxidative activation of mtMGST1. In the present study, we aimed to determine whether mtMGST1 also undergoes activation and about its function.
