ID:PRDX3_HUMAN DESCRIPTION: RecName: Full=Thioredoxin-dependent peroxide reductase, mitochondrial; EC=1.11.1.15; AltName: Full=Antioxidant protein 1; Short=AOP-1; AltName: Full=HBC189; AltName: Full=Peroxiredoxin III; Short=Prx-III; AltName: Full=Peroxiredoxin-3; AltName: Full=Protein MER5 homolog; Flags: Precursor; FUNCTION: Involved in redox regulation of the cell. Protects radical-sensitive enzymes from oxidative damage by a radical- generating system. Acts synergistically with MAP3K13 to regulate the activation of NF-kappa-B in the cytosol. CATALYTIC ACTIVITY: 2 R'-SH + ROOH = R'-S-S-R' + H(2)O + ROH. SUBUNIT: Dodecameric ring assembled from homodimeric units; disulfide-linked, upon oxidation. The rings have an approximate diameter of 150 A and a central hole of 70 A. 3-5% of the rings are interlocked by pairs. Binds MAP3K13. Interacts with NEK6. Interacts with LRRK2. SUBCELLULAR LOCATION: Mitochondrion. PTM: Phosphorylated by LRRK2; phosphorylation reduces perodixase activity. MISCELLANEOUS: The active site is the redox-active Cys-108 oxidized to Cys-SOH. Cys-SOH rapidly reacts with Cys-229-SH of the other subunit to form an intermolecular disulfide with a concomitant homodimer formation. The enzyme may be subsequently regenerated by reduction of the disulfide by thioredoxin. MISCELLANEOUS: Irreversibly inactivated by overoxidation of Cys- 108 (to Cys-SO(3)H) upon oxidative stress. SIMILARITY: Belongs to the AhpC/TSA family. SIMILARITY: Contains 1 thioredoxin domain. WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/prdx3/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
