Background

CEACAM-5, also known as CEA and CD66e, belongs to the large family of CEACAM and pregnancy specific glycoproteins. CEACAM-5 functions as a calcium independent adhesion molecule through homophilic and heterophilic interactions with CEACAM-1. CEA is restricted to the apical face of intestinal epithelial cells in the adult but is more diffuse during embryonic development and in tumors. This is consistent with a role in the development and maintenance of epithelial architecture. It is upregulated in a wide variety of human tumors and is a commonly used cancer marker. It promotes tumor cell migration, invasion, adhesion, and metastasis. CEACAM-5 also contributes to tumor formation by maintaining cellular proliferation in the presence of differentiation stimuli, and by blocking apoptosis following loss of ECM anchorage.
