Tumor-associated glycoprotein 72
Tumor-associated glycoprotein 72 (TAG-72) is a glycoprotein found on the surface of many cancer cells, including ovary,[1][2][3] breast, colon,[4] lung, and pancreatic cancers.[5][6] It is a mucin-like molecule with a molar mass of over 1000 kDa.[7]
TAG-72 is a tumor marker measured with radioimmunoassays like CA 72-4, which uses the monoclonal antibodies indium (111In) satumomab pendetide and iodine (125I) minretumomab.[8][9][10][11][12] This assay has a good specificity for gastric cancer, with a correlation to the neoplasia's extension. It is used to identify relapses of the disease and to follow up the treatment.
TAG-72 is also the target of the anti-cancer drugs anatumomab mafenatox and minretumomab.
