Recombinant Human CEACAM1 Peptide

Description: The human carcinoembryonic antigen (CEA) family is composed of 29 genes tandemly arranged on chromosome 19q13.2 Based on nucleotide homologies, these genes are classified into 2 major subfamilies, the CEACAM and the pregnancy-specific glycoprotein (PSG) subgroups. The CEACAM-encoded proteins include CEA, CEACAM-1, and other CEA gene members.

The CEA-related cell adhesion molecule 1, CEACAM-1, is a glycoprotein expressed on the surface of human granulocytes and lymphocytes, endothelia, and many ephitelia, where it has been assigned to the CD66 cluster. CEACAM-1 is involved in the regulation of important biological processes, such as tuomr growth, angiogenesis, and modulation of the immune response. In addition, CEACAM-1 is a receptor of bacteria, such as Neisseria, Haemophilus influenzae, and Moraxella catarrhalis. The binding of Opa (opacity proteins adhesins of N. meninigitidis) occurs at the non-glycosylated face of the N-domain of CEACAM-1; heterophilic adhesion facilitates bacterial colonization of the gut and bacterial phagocytosis by neutrophilis; and is involved in the granulocytes migration during inflammatory responses. The N-terminal domain of CEACAM-1 has been implicated also in mediating homophilic adhesion. (...more...)
