EGFR and colorectal carcinoma: Quantitative analysis of these N‐glycosylation sites revealed that most IGPs are membrane‐bound or secreted proteins, some of which, such as EGFR, Mucin‐2 (MUC2), and Carcinoembryonic antigen‐related cell adhesion molecule 5 (CEACAM5), are established cancer biomarkers in immunotherapy.[24, 43, 44] Our analysis particularly highlights the disparity between sialylated and high mannosylated N‐glycans in CRC‐associated glycoproteins.
