Anti-GSTA2-2 antibodies enable researchers to detect and measure the GSTA2-2 antigen in biological samples. This target is a reported synonym of the GSTA2 gene, which encodes glutathione S-transferase alpha 2. This protein is known to function in epithelial cell differentiation, among other biological roles. The human version of GSTA2-2 has a canonical amino acid length of 222 residues and a protein mass of 25.7 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the duodenum and liver. Other names for this target antigen include GST2 and GTA2.
