Methionine-R-sulfoxide reductase B1; Methionine-sulfoxide reductase that specifically reduces methionine (R)-sulfoxide back to methionine. While in many cases, methionine oxidation is the result of random oxidation following oxidative stress, methionine oxidation is also a post-translational modification that takes place on specific residue. Acts as a regulator of actin assembly by reducing methionine (R)-sulfoxide mediated by MICALs (MICAL1, MICAL2 or MICAL3) on actin, thereby promoting filament repolymerization. Plays a role in innate immunity by reducing oxidized actin, leading to a [...]

Thioredoxin; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (By similarity). Plays a role in the reversible S-nitrosylation of cysteine residues in target proteins, and thereby contributes to the response to intracellular nitric oxide. Nitrosylates the active site Cys of CASP3 in response to nitric oxide (NO), and thereby inhibits caspase-3 activity. Induces the FOS/JUN AP-1 DNA binding activity in ionizing radiation (IR) cells through its oxidation/reduction status [...]

ATP-dependent Clp protease ATP-binding subunit clpX-like, mitochondrial; ATP-dependent specificity component of the Clp protease complex. Hydrolyzes ATP. Targets specific substrates for degradation by the Clp complex. Can perform chaperone functions in the absence of CLPP. Enhances the DNA-binding activity of TFAM and is required for maintaining a normal mitochondrial nucleoid structure. ATP-dependent unfoldase that stimulates the incorporation of the pyridoxal phosphate cofactor into 5-aminolevulinate synthase, thereby activating 5- aminolevulinate (ALA) synthesis, the first step in h [...]

Thioredoxin reductase-like selenoprotein T; Selenoprotein with thioredoxin reductase-like oxidoreductase activity. Protects dopaminergic neurons against oxidative stress ans cell death (By similarity). Involved in ADCYAP1/PACAP-induced calcium mobilization and neuroendocrine secretion. Plays a role in fibroblast anchorage and redox regulation (By similarity). In gastric smooth muscle, modulates the contraction processes through the regulation of calcium release and MYLK activation. In pancreatic islets, involved in the control of glucose homeostasis, contributes to prolonged ADCYAP1/PA [...]

Selenoprotein F; May be involved in redox reactions associated with the formation of disulfide bonds. May contribute to the quality control of protein folding in the endoplasmic reticulum. May regulate protein folding by enhancing the catalytic activity of UGGT1/UGCGL1 and UGGT2/UGCGL2 (By similarity). Belongs to the selenoprotein M/F family.

Mitochondrial ribosomal protein L20; Belongs to the bacterial ribosomal protein bL20 family.

Selenoprotein O.

Catalase; Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells; Belongs to the catalase family.

Thioredoxin reductase 2, mitochondrial; Involved in the control of reactive oxygen species levels and the regulation of mitochondrial redox homeostasis (By similarity). Maintains mitochondrial thioredoxin in a reduced state. May play a role in redox-regulated cell signaling.
