Rabbit anti-Human GPX2 Polyclonal Antibody

Uniprot Id

P18283

Target Species

Human

Target Name

GPX2

Target Full Name

Glutathione peroxidase 2

Target Function

Could play a major role in protecting mammals from the toxicity of ingested organic hydroperoxides. Tert-butyl hydroperoxide, cumene hydroperoxide and linoleic acid hydroperoxide but not phosphatidycholine hydroperoxide, can act as acceptors.

Target Subcellular Location

Cytoplasm. Note=Mainly cytoplasmic.

Target Protein Families

Glutathione peroxidase family

Target Tissue Specificity

Mostly in liver and gastrointestinal tract, not found in heart or kidney.

Target Synonyms

Gastrointestinal glutathione peroxidase; GI GPx; Glutathione peroxidase 2 (gastrointestinal); Glutathione peroxidase 2; Glutathione peroxidase gastrointestinal; Glutathione peroxidase related protein 2; Glutathione peroxidase-gastrointestinal; Glutathione peroxidase-related protein 2; GPRP; GPRP-2; GPx 2; GPx-2; GPx-GI; GPX2; GPX2_HUMAN; GSHPx 2; GSHPx GI; GSHPx-2; GSHPx-GI

Target Background

The protein encoded by this gene belongs to the glutathione peroxidase family, members of which catalyze the reduction of organic hydroperoxides and hydrogen peroxide (H2O2) by glutathione, and thereby protect cells against oxidative damage. Several isozymes of this gene family exist in vertebrates, which vary in cellular location and substrate specificity. This isozyme is predominantly expressed in the gastrointestinal tract (also in liver in human), is localized in the cytoplasm, and whose preferred substrate is hydrogen peroxide. Overexpression of this gene is associated with increased differentiation and proliferation in colorectal cancer. This isozyme is also a selenoprotein, containing the rare amino acid selenocysteine (Sec) at its active site. Sec is encoded by the UGA codon, which normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon, rather than as a stop signal. Alternatively spliced transcript variants have been found for this gene.
