Glutathione peroxidase 2
Function
Catalyzes the reduction of hydroperoxides in a glutathione-dependent manner thus regulating cellular redox homeostasis (PubMed:36608588, PubMed:8428933). Can reduce small soluble hydroperoxides such as H2O2, cumene hydroperoxide and tert-butyl hydroperoxide, as well as several fatty acid-derived hydroperoxides (PubMed:36608588, PubMed:8428933). Cannot reduce phosphatidycholine hydroperoxide (PubMed:8428933).
Sequence Similarities
Belongs to the glutathione peroxidase family.
Tissue Specificity
Mostly in liver and gastrointestinal tract, not found in heart or kidney.
Cellular localization
- Cytoplasm
- Cytosol
