Background: CEACAM-18

Carcinoembryonic Antigen-related Cell Adhesion Molecule 18 (CEACAM-18) is part of the CEA protein family consisting of CEACAMs and the pregnancy-specific glycoproteins (PSGs). Both CEACAM and PSG molecules have been identified in humans and belong to the much larger glycosylphosphatidylinositol (GPI)-linked immunoglobulin (Ig) superfamily (1, 2). Mature human CEACAM-18 has a 298 amino acid (aa) extracellular domain containing 2 IgC2-like and 1 IgV-like domains, a single transmembrane domain and a short cytoplasmic tail (2). CEACAM-18 is one of only five conserved CEACAMs among mouse, rat, and human (2), but mature human CEACAM-18 has low aa sequence identify with mouse and rat at 60% and 58%, respectively. Originally discovered as a biomarker for colorectal cancer (3), CEACAMs have now been associated with numerous intracellular signaling processes including cell adhesion, cell growth, recognition and differentiation, angiogenesis, and apoptosis (4-6). While the exact function of CEACAM-18 has been yet to be elucidated, it may bind pathogen receptors or other immunoregulatory members (6). CEACAM family members were identified as the major Galectin-3 receptor candidates on human neutrophils (7). Binding of carbohydrate ligands to CEACAMs may be important in the release of proinflammatory mediators (8, 9).
