FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene belongs to the glutathione peroxidase family. It is specifically expressed in the epididymis in the mammalian male reproductive tract, and is androgen-regulated. Unlike several other characterized glutathione peroxidases, this enzyme is not a selenoprotein, lacking the selenocysteine residue. Thus, it is selenium-independent, and has been proposed to play a role in protecting the membranes of spermatozoa from the damaging effects of lipid peroxidation and/or preventing premature acrosome reaction. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2016]
PHENOTYPE: Male mice homozygous for a knock-out allele exhibit age-dependent reduced fertility due to increased sensitivity of sperm DNA to oxidative attack. [provided by MGI curators]
