Technical Data
CEACAM 6 (Carcinoembryonic Antigen (CEA)-Related Cell Adhesion Molecule 6, Non-specific Cross-reacting Antigen, Normal Cross-reacting Antigen, NCA, CD66c)
CEACAM6 is a GPI-anchored membrane protein with a single N domain, which shows structural homology to the immunoglobulin variable domains, followed by two immunoglobulin constant-like domains. CEA-related cell adhesion molecule 6 (CEACAM6, NCA) belongs to the carcinoembryonic antigen (CEA) gene family (1,2). It encodes a glycosyl phosphatidyl inositol (GPI)-linked glycoprotein with a Mr of 90,000 which is strongly expressed on epithelial cells of the fetal and adult gastrointestinal tract, epithelia of glandular tissues, squamous epithelial cell of the tongue, esophagus and cervix as well as on granulocytes (2,3). CEACAM6 expression is upregulated in many adenocarcinomas and leukemias. Like all members of the CEA family, it consists of a single N domain, with structural homology to the immunoglobulin variable domains, followed by one immunoglobulin constant-like A and B domain. This clone can be used to distinguish CEACAM6 from all other CEACAM and probably all pregnancy-specific glycoprotein molecules, namely CEACAM1 (BGP/CD66a), CEACAM3 (CGM1/CD66d), CEACAM4 (CGM7), CEACAM7 (CGM2), CEACAM8 (CGM6/CD66b) and PSG1 (CD66f) based on its reactivity pattern with stable HeLa transfectants expressing individual CEA family members.
