Beschreibung: CEA-related cell adhesion molecules (CEACAM) belong to the carcinoembryonic antigen (CEA) family (13). It consists of seven CEACAM (CEACAM1, CEACAM3-CEACAM8) and 11 pregnancy-specific glyco-protein (PSG1- PSG11) members. The CEA family proteins belong to the immunoglobulin (Ig) superfamily and are composed of one Ig variable-like (IgV) and a varying number (0-6) of Ig constant-like (IgC) domains (Fig. 2). CEACAM molecules are membrane-bound either via a transmembrane domain or a glycosyl phosphatidyl inositol (GPI) anchor (Fig. 2). CEACAM molecules are differentially expressed in epithelial cells or in leucocytes. Over-expression of CEA/ CEACAM5 in tumors of epithelial origin is the basis of its wide-spread use as a tumor marker (5). The function of CEACAM family members varies widely: they function as cell adhesion molecules, tumor suppressors, regulators of lymphocyte and dendritic cell activation, receptors of Neisseria species and other bacteria (13).
