Anti-CEA cell adhesion molecule 7 antibodies are used for the immunodetection of the protein encoded by the CEACAM7 gene. In humans, the canonical protein has a reported length of 265 amino acid residues and a mass of 29.3 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in columnar epithelial cells of the colon. A member of the CEA protein family, it is known to be involved with signal transduction pathways. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include carcinoembryonic antigen-related cell adhesion molecule 7, carcinoembryonic antigen CGM2, carcinoembryonic antigen gene family member 2, and CGM2. Gene orthologs have been identified in the mouse and chimpanzee species.
