CC   -!- FUNCTION: Protects the hemoglobin in erythrocytes from oxidative
CC       breakdown. In platelets, plays a crucial role of glutathione peroxidase
CC       in the arachidonic acid metabolism. {ECO:0000250|UniProtKB:P11352}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 glutathione + H2O2 = glutathione disulfide + 2 H2O;

CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(12S)-hydroperoxy-(5Z,8Z,10E,14Z)-eicosatetraenoate + 2
CC         glutathione = (12S)-hydroxy-(5Z,8Z,10E,14Z)-eicosatetraenoate +

CC         Evidence={ECO:0000250|UniProtKB:P11352};
CC   -!- SUBUNIT: Homotetramer. Interacts with MIEN1 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- PTM: During periods of oxidative stress, Sec-47 may react with a
CC       superoxide radical, irreversibly lose hydroselenide and be converted to
CC       dehydroalanine. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glutathione peroxidase family.
CC       {ECO:0000305}.
