Background: CEACAM-5/CD66e

CEACAM-5, also known as CEA, CD66e and Psg30, belongs to the large family of CEACAM and pregnancy specific glycoproteins. CEACAM family members are highly glycosylated with varying arrangements of IgV-like and IgC-like regions in their extracellular domains (ECD) and can be expressed as transmembrane, glycophosphatidyl inositol (GPI) linked or soluble proteins (1-3). CEACAM-5 consists of an N-terminal Ig-like V-set domain followed by six Ig-like C2-set domains and a GPI anchor (2, 4, 5). While the mature ECD of mouse CEACAM-5 shares 26% amino acid identity with human CEACAM-5, it remains unclear if these molecules are direct orthologs (6). CEACAM-5, expressed primarily by epithelial cells, functions as a calcium-independent adhesion molecule through homophilic and heterophilic interactions with CEACAM-1 (1, 7). CEACAM-5 is restricted to the apical face of intestinal epithelial cells in the adult but is more diffuse during embryonic development and in tumors (8). This is consistent with a role in the development and maintenance of epithelial architecture. CEACAM-5 is up-regulated in a wide variety of human tumors, promoting tumor cell migration, invasion, adhesion, and metastasis, and has been used as a cancer marker (8, 9). It also contributes to tumor formation by maintaining cellular proliferation in the presence of differentiation stimuli, and by blocking apoptosis following loss of ECM anchorage (anoikis) (10, 11). The GPI anchoring of CEACAM-5 can be released by GPI-PLD, resulting in a soluble molecule that also promotes tumor metastasis (12). Cell surface expression of CEACAM-5 on tumor cells prevents the adhesion of CEACAM-1 expressing NK cells and provides protection from NK-mediated lysis (8). CEACAM-5 was shown to bind galectin-4 and by surface plasmon resonance and coimmunoprecipitated with galectin-4 in human colon adenocarcinoma LS174T cell lysates (13). CEACAM-5 also binds a subset of Neisseria opacity proteins (Opa) and E. coli adhesion proteins (14, 15). These interactions trigger clustering of the lipid raft-localized CEACAM-5 to sites of pathogen contact (15, 16).
