The carcinoembryonic antigen (CEA) protein is a cell surface glycoprotein. CEA plays a role as an oncogene by promoting tumor progression through its modulation of cell adhesion and intracellular signaling, and inducing resistance to anoikis of colorectal carcinoma cells. CEA is therefore useful as a clinical biomarker for gastrointestinal cancers.
