This rabbit polyclonal antibody was generated against mouse carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) 6.5 kD long intracytoplasmic domain produced as a GST fusion protein, but cleaved from the GST.
CEACAM1 (biliary glycoprotein) is a cell adhesion molecule with reduced expression in early phases of CRC development and thus functions as a tumor growth inhibitor. This gene encodes a member of the carcinoembryonic antigen (CEA) gene family, which belongs to the immunoglobulin superfamily. Two subgroups of the CEA family, the CEA cell adhesion molecules and the pregnancy-specific glycoproteins, are located within a 1.2 Mb cluster on the long arm of chromosome 19 and the mouse CEACAM1 gene is located on mouse chr. 7. The encoded protein was originally described in bile ducts of liver as biliary glycoprotein. Subsequently, it was found to be a cellcell adhesion molecule detected on leukocytes, epithelia, and endothelia. Multiple cellular activities have been attributed to the encoded protein, including roles in the differentiation and arrangement of tissue three-dimensional structure, angiogenesis, apoptosis, tumor suppression, metastasis, and the modulation of innate and adaptive immune responses. Multiple transcript variants encoding different isoforms have been reported, but the full-length nature of only two has been determined.
