Protein attributes

Sequence length	221 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Protects cells and enzymes from oxidative damage, by catalyzing the reduction of hydrogen peroxide, lipid peroxides and organic hydroperoxide, by glutathione. May constitute a glutathionine peroxidase-like protective system against peroxide damage in sperm membrane lipids.
Catalytic activity	2 glutathione + H2O2 = glutathione disulfide + 2 H2O.
Subcellular location	Secreted.
Tissue specificity	Epididymis.
Sequence similarities	Belongs to the glutathione peroxidase family.
