Comments

FUNCTION: Could play a major role in protecting mammals from the toxicity of ingested lipid hydroperoxides. Essential for embryonic development. Protects from radiation and oxidative damage (By similarity).
CATALYTIC ACTIVITY: 2 glutathione + a lipid hydroperoxide = glutathione disulfide + lipid + 2 H₂O.
SUBCELLULAR LOCATION: Mitochondrion (By similarity). Cytoplasm (By similarity).

ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative initiation.

Name	Mitochondrial
Isoform ID	Q4AEH2-1
This is the isoform sequence displayed in this entry.

Name	Cytoplasmic
Isoform ID	Q4AEH2-2
Features which should be applied to build the isoform sequence: VSP_018745.

SIMILARITY: Belongs to the glutathione peroxidase family.
