Summary
Enables thioredoxin-disulfide reductase (NADPH) activity. Predicted to be involved in cell differentiation; cellular oxidant detoxification; and spermatogenesis. Predicted to act upstream of or within cellular response to reactive oxygen species and flagellated sperm motility. Located in cytoplasm. [provided by Alliance of Genome Resources, Nov 2024]

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.

  1. NM_001098529.2NP_001091999.1  thioredoxin domain-containing protein 2 isoform 2

    See identical proteins and their annotated locations for NP_001091999.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) uses a different splice site, resulting in a longer open reading frame through the use of an upstream start codon, compared to variant 1. The predicted protein (isoform 2) has a longer N-terminus compared to isoform 1.
