Glutathione peroxidase refers to a family of isozymes that protect organisms from oxidative damage by reducing lipid hydroperoxides to their corresponding alcohols. Glutathione peroxidase 3 (GPX3) is an extracellular Gpx isozyme found mainly in plasma.
Synonyms: Anti-GPx-P; Anti-GSHPx-3; Anti-GSHPx-P; Anti-Glutathione Peroxidase 3 (plasma)
Storage: -20C
Application: Anti-GPX3 polyclonal antibody is used to tag glutathione peroxidase-3 protein for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to study the antioxidant lipid protecting role of glutathione peroxidase 3 in extracellular space and plasma.
Biochem Physiol Actions: GPX3 belongs to the glutathione peroxidase family, which functions in the detoxification of hydrogen peroxide. It contains a selenocysteine (Sec) residue at its active site. The selenocysteine is encoded by the UGA codon, which normally signals translation termination.Glutathione peroxidase catalyzes the reduction of hydrogen peroxide, organic hydroperoxide, and lipid peroxides by reduced glutathione and functions in the protection of cells against oxidative damage. Human plasma glutathione peroxidase has been shown to be a selenium-containing enzyme. GPX3 expression appears to be tissue-specific.
