Anti-Mart2 antibodies enable researchers to detect and measure the Mart2 antigen in biological samples. This target is a reported synonym of the PEG10 gene, which encodes paternally expressed 10. This protein is known to function in the apoptotic pathway and cell differentiation, among other biological roles. The human version of Mart2 has a canonical amino acid length of 708 residues and a protein mass of 80.2 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the testis, skin, placenta, and adrenal gland.
