    Summary
    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]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      Description
      Transcript Variant: This variant (2) lacks an internal coding exon, which results in a frame-shift, compared to variant 1. The encoded isoform (2) is shorter, with a distinct C-terminus compared to isoform 1.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (3) contains an alternate 5' terminal exon and lacks an internal exon compared to variant 1. It is represented as non-coding because the use of the 5'-most translation start codon, as used in variant 1, renders this transcript a candidate for nonsense-mediated mRNA decay (NMD).
