Possibly the most extensively researched tumor-associated glycans consist of variations arising from a premature termination of protein O-glycosylation called the Tn antigen (the most basic O-glycan), its sialylated counterpart sialyl-Tn (sTn; Neu5Acα2-6GalNAcα-O-Ser/Thr), and the T or core 1 antigen which arises following the addition of a Gal residue to the Tn antigen (Galβ1-3GalNAc-Ser/Thr) (Julien et al., 2011). Here, EEF1A2 is linked to neoplasm.
