The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Biological activitySpecific activity: approximately 600-670 pmole/min/µg.
Enzymatic activity was confirmed by measuring the remaining peroxide after incubation of PRDX1 and peroxide for 20 min at room temperature. Specific activity is defined as the amount of hydroperoxide that 1ug of enzyme can reduce at 25 C for 1 minute.
% SDS-PAGE. ab74172 is purified by conventional chromatography techniques.

Thioredoxin peroxidase 2
Thioredoxin-dependent peroxide reductase 2
FunctionInvolved in redox regulation of the cell. Reduces peroxides with reducing equivalents provided through the thioredoxin system but not from glutaredoxin. May play an important role in eliminating peroxides generated during metabolism. Might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2). Reduces an intramolecular disulfide bond in GDPD5 that gates the ability to GDPD5 to drive postmitotic motor neuron differentiation.
Sequence similaritiesBelongs to the ahpC/TSA family. Contains 1 thioredoxin domain.
Post-translational modificationsPhosphorylated on Thr-90 during the M-phase, which leads to a more than 80% decrease in enzymatic activity.
Cellular localizationCytoplasm. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
