Comments
Comment typeDescription
Alternative ProductsEvent=Alternative initiation; Named isoforms=2; Name=Mitochondrial; IsoId=P36969-1; Sequence=Displayed; Name=Cytoplasmic; IsoId=P36969-2; Sequence=VSP_018740;
Catalytic Activity2 glutathione + a lipid hydroperoxide = glutathione disulfide + lipid + 2 H(2)O.
DiseaseSpondylometaphyseal dysplasia, Sedaghatian type (SMDS) [MIM
FunctionProtects cells against membrane lipid peroxidation and cell death. Required for normal sperm development and male fertility. 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).
SimilarityBelongs to the glutathione peroxidase family.
Subcellular LocationIsoform Cytoplasmic: Cytoplasm.
Subcellular LocationIsoform Mitochondrial: Mitochondrion.
SubunitMonomer. Has a tendency to form higher mass oligomers.
Tissue SpecificityPresent primarily in testis.
