Grx2 and Trx1 (zeige MLL ELISA Kits) contribute significantly to neuronal integrity and could be clinically relevant in neuronal damage following perinatal asphyxia and other neuronal disorders.
The Grx2 system could help to keep Trx2 (zeige TXN2 ELISA Kits)/1 reduced during an oxidative stress, thereby contributing to the anti-apoptotic signaling.
Grx2 thiol redox regulation is essential for vertebrate embryonic development
Exchange of [2Fe-2S] centers between glutaredoxin 2 and the cluster scaffold protein (zeige HOMER1 ELISA Kits) ISU, supports a direct link for glutaredoxin 2 and glutathione involvement in ISU promoted Fe-S cluster biosynthesis.
Both thioredoxin 2 (zeige TXN2 ELISA Kits) and glutaredoxin 2 contribute to the reduction of the mitochondrial 2-Cys (zeige DNAJC5 ELISA Kits) peroxiredoxin Prx3 (zeige PRDX3 ELISA Kits).
Studies indicate that the mechanism of Grx2 protection against H(2)O(2)-induced apoptosis is likely associated with its ability to preserve complex I.
results suggest an important role for glutaredoxin 2 in protection and recovery from oxidative stress
Grx1 (zeige GRX1 ELISA Kits) and Grx2 were present in placenta extracts and in cell lysates prepared from tumor cell lines; however, the levels of Grx1 (zeige GRX1 ELISA Kits) were at least 20 times higher than those of Grx2; Grx2 was not detected in plasma from healthy blood donors
Lung cells can synthesize Grx2 mRNA and protein.
characterization of Grx2 as an iron-sulfur center-containing member of the thioredoxin (zeige TXN ELISA Kits) fold protein family
pre-incubation of permeabilized liver mitochondria from mouse depleted of GSH showed an approximately ~3.5-fold increase in Ogdh (zeige alphaKGDHC ELISA Kits)-mediated O2(-)/H2O2 production that was matched by a significant decrease in NADH formation which could be reversed by Grx2. Taken together, our results demonstrate GSH and GSSG modulate ROS (zeige ROS1 ELISA Kits) production by Ogdh (zeige alphaKGDHC ELISA Kits) through S-glutathionylation of different subunits
Increasing Grx2a activity in macrophage mitochondria disrupts mitochondrial respiration and ATP production, but without affecting the proatherogenic potential of macrophages from LDL receptor (zeige LDLR ELISA Kits) knockout mice.
Grx2 gene deletion altered the function of lens structural proteins through S-glutathionylation and also caused severe disturbance in mitochondrial function.
The results suggest that Glrx2b enhances RANKL (zeige TNFSF11 ELISA Kits)-induced osteoclastogenesis via p38 (zeige CRK ELISA Kits) activation.
Data indicate that glutaredoxin-2 (Grx2) plays a vital role in modulating mitochondrial metabolism in cardiac muscle, and Grx2 deficiency leads to pathology.
Grx2 deactivates UCP3 (zeige UCP3 ELISA Kits) by glutathionylation.
Grx2 has a function that protects cells against H(2)O(2)-induced injury via its peroxidase and dethiolase activities; particularly, Grx2 prevents complex I inactivation and preserves mitochondrial function.
Immunohistochemical analysis revealed segment-specific alterations induced by the ischemic insult. Grx2, Prx3 (zeige PRDX3 ELISA Kits), and Prx6 (zeige PRDX6 ELISA Kits) were highly expressed in proximal tubule cells
Data indicate that glutaredoxin 2 plays a central role in the response of mitochondria to both redox signals and oxidative stress by facilitating the interplay between the mitochondrial glutathione pool and protein thiols.
The protein encoded by this gene is a member of the glutaredoxin family of proteins, which maintain cellular thiol homeostasis. These proteins are thiol-disulfide oxidoreductases that use a glutathione-binding site and one or two active cysteines in their active site. This gene undergoes alternative splicing to produce multiple isoforms, one of which is ubiquitously expressed and localizes to mitochondria, where it functions in mitochondrial redox homeostasis and is important for the protection against and recovery from oxidative stress. Other isoforms, which have more restrictive expression patterns, show cytosolic and nuclear localization, and are thought to function in cellular differentiation and transformation, possibly with a role in tumor progression.
