The molecular basis of antibody 5E5, which recognizes the entire GalNAc unit as a primary epitope is now disclosed. The antibody’s contacts with the peptide are mostly limited to two residues, allowing it to show some degree of promiscuity. These findings open the door to the chemical design of peptide mimetics for developing efficient anti-cancer vaccines and diagnostic tools.
