功能Involved 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.
序列相似性Belongs to the ahpC/TSA family. Contains 1 thioredoxin domain.
翻译后修饰Phosphorylated on Thr-90 during the M-phase, which leads to a more than 80% decrease in enzymatic activity.
细胞定位Cytoplasm. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
