Anti-Glutaredoxin 3 antibodies are used for the immunodetection of the protein encoded by the GLRX3 gene. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 37.4 kDa. Its subcellular localization is in the cytoplasm. It is found to be expressed in the heart, spleen, testis and, to a lower extent, in thymus and peripheral blood leukocytes. Other names for this target antigen include GRX3, GRX4, PICOT, TXNL2, TXNL3, PKC-interacting cousin of thioredoxin, PKC-theta-interacting protein, and GLRX4. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Glutaredoxin 3 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
