Recombinant Human Thioredoxin-dependent peroxide reductase, mitochondrial (PRDX3)

Uniprot Id

P30048

Target Species

Human

Target Name

PRDX3

Target Full Name

Thioredoxin-dependent peroxide reductase, mitochondrial

Target Function

Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. Acts synergistically with MAP3K13 to regulate the activation of NF-kappa-B in the cytosol.

Target Subcellular Location

Mitochondrion. Cytoplasm. Early endosome.

Target Protein Families

Peroxiredoxin family, AhpC/Prx1 subfamily

Target Research Area

Cancer

Target Background

This gene encodes a mitochondrial protein with antioxidant function. The protein is similar to the C22 subunit of Salmonella typhimurium alkylhydroperoxide reductase, and it can rescue bacterial resistance to alkylhydroperoxide in E. coli that lack the C22 subunit. The human and mouse genes are highly conserved, and they map to the regions syntenic between mouse and human chromosomes. Sequence comparisons with recently cloned mammalian homologs suggest that these genes consist of a family that is responsible for the regulation of cellular proliferation, differentiation and antioxidant functions. This family member can protect cells from oxidative stress, and it can promote cell survival in prostate cancer. Alternative splicing of this gene results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 1, 3, 13 and 22.
