General annotation (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. Cytoplasm.

Tissue specificity

Present primarily in testis. Expressed in flagella of epididymal sperm. Ref.6

Sequence similarities

Belongs to the glutathione peroxidase family.

Alternative products

This entry describes 3 isoforms produced by alternative splicing and alternative initiation. [Align] [Select]
Isoform Mitochondrial (identifier: P36970-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform Nuclear (identifier: Q91XR8-1)

The sequence of this isoform can be found in the external entry Q91XR8.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.
Isoform Cytoplasmic (identifier: P36970-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-27: Missing.
Note: Produced by alternative initiation at Met-28 of isoform Mitochondrial.
