Anti-CHAC2 antibodies are used in the immunodetection of the protein ChaC glutathione specific gamma-glutamylcyclotransferase 2. In humans, the canonical protein has a reported length of 184 amino acid residues and a mass of 20.9 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in many tissues, such as the esophagus and skin. A member of the Gamma-glutamylcyclotransferase protein family, CHAC2 is known to catalyze the cleavage of glutathione into 5-oxo-L-proline and a Cys-Gly dipeptide. Synonyms for this target antigen include ChaC cation transport regulator homolog 2, ChaC, cation transport regulator-like 2, cation transport regulator-like protein 2, gamma-GCG 2, and glutathione-specific gamma-glutamylcyclotransferase 2. CHAC2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CHAC2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
