  • 产品描述：
    GPX4 polyclonal antibody CSB-PA03049A0Rb was produced in the rabbit immunized by using the Recombinant Human Phospholipid hydroperoxide glutathione peroxidase, mitochondrial protein (74-197AA) as the immunogen. The target protein GPX4 belongs to the glutathione peroxidase family, members of which catalyze the reduction of hydrogen peroxide, organic hydroperoxides and lipid hydroperoxides. It plays a key role in protecting cells from oxidative damage by preventing membrane lipid peroxidation. Diseases associated with GPX4 include Spondylometaphyseal Dysplasia, Sedaghatian Type and Male Infertility.
    This Rabbit anti-Homo sapiens (Human) GPX4 Polyclonal antibody was tested in the ELISA, WB, IHC and IF applications. The non-conjugated IgG got purified by protein G and reached up to 95% in purity. It reacts with the GPX4 proteins of human or mouse or rat-origin and may be used to detect the endogenous levels of GPX4 protein.

  • 功能：
    Essential antioxidant peroxidase that directly reduces phospholipid hydroperoxide even if they are incorporated in membranes and lipoproteins. Can also reduce fatty acid hydroperoxide, cholesterol hydroperoxide and thymine hydroperoxide. Plays a key role in protecting cells from oxidative damage by preventing membrane lipid peroxidation. Required to prevent cells from ferroptosis, a non-apoptotic cell death resulting from an iron-dependent accumulation of lipid reactive oxygen species. The presence of selenocysteine (Sec) versus Cys at the active site is essential for life: it provides resistance to overoxidation and prevents cells against ferroptosis. The presence of Sec at the active site is also essential for the survival of a specific type of parvalbumin-positive interneurons, thereby preventing against fatal epileptic seizures. May be required to protect cells from the toxicity of ingested lipid hydroperoxides. Required for normal sperm development and male fertility. Essential for maturation and survival of photoreceptor cells. Plays a role in a primary T-cell response to viral and parasitic infection by protecting T-cells from ferroptosis and by supporting T-cell expansion. Plays a role of glutathione peroxidase in platelets in the arachidonic acid metabolism. Reduces hydroperoxy ester lipids formed by a 15-lipoxygenase that may play a role as down-regulator of the cellular 15-lipoxygenase pathway.
