  • Function
    Glutathione-dependent oxidoreductase that facilitates the maintenance of mitochondrial redox homeostasis upon induction of apoptosis by oxidative stress. Involved in response to hydrogen peroxide and regulation of apoptosis caused by oxidative stress. Acts as a very efficient catalyst of monothiol reactions because of its high affinity for protein glutathione-mixed disulfides. Can receive electrons not only from glutathione (GSH), but also from thioredoxin reductase supporting both monothiol and dithiol reactions. Efficiently catalyzes both glutathionylation and deglutathionylation of mitochondrial complex I, which in turn regulates the superoxide production by the complex. Overexpression decreases the susceptibility to apoptosis and prevents loss of cardiolipin and cytochrome c release.
  • Tissue specificity
    Widely expressed. Expressed in brain, heart, skeletal muscle, colon, thymus, spleen, kidney, liver, small intestine, placenta and lung. Not expressed in peripheral blood leukocytes.
  • Sequence similarities

  • Anti-Glutaredoxin 2 antibody - C-terminal (ab85267) at 1/50 dilution + mouse cerebellum tissue lysates at 35 µg

    Predicted band size: 18 kDa
    Observed band size: 25 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 40 kDa. We are unsure as to the identity of these extra bands.

  • ICC/IF image of ab85267 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab85267, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your response.

Unfortunately, the two attached images have not gone through successfully so I am unable to open them. It is reassuring that Gelsolin and Beta-actin antibodies provide clear signal but they are not positive contro...

Thank you for sending me your data and details of your protocol.  As we discussed, it is probable that the lowest band is the Glutaredoxin 2 protein, but I have no information as to why the band would appear in one sample and not the other.  You may be...
