Background

Carcinoembryonic antigen-related cell adhesion molecule 8 (CEACAM-8), also known as CGM6 and CD66b, is an approximately 95 kDa member of the human carcinoembryonic antigen (CEA) family that plays a role in cell adhesion, cell migration and pathogen binding. Human CEACAM-8 is composed of a 34 amino acid (aa) signal peptide, a 29 aa propeptide segment which is removed in the mature form, and a 286 aa CEACAM-8 region containing one V-type and two C2-type Ig-like domains. CEACAM family members are widely expressed in epithelial, endothelial, and hematopoietic cells, including neutrophils, T-cells, and NK cells. CEACAMs appear to be capable of transmitting signals that result in a variety of effects depending on the tissue, including tumor suppression, tumor promotion, angiogenesis, neutrophil activation, lymphocyte activation, regulation of the cell cycle, and regulation of adhesion. CEACAMs have now been associated with numerous intracellular signaling processes including cell adhesion, cell growth, recognition and differentiation, angiogenesis, and apoptosis.
