Campbell, IG, Foulkes, WD, Senger, G, Trowsdale, J, Garin-Chesa, P and Rettig, WJ (1994) Molecular cloning of the B-CAM cell surface glycoprotein of epithelial cancers: a novel member of the immunoglobulin superfamily. Cancer Res. 54:5761-5


The human F8/G253 antigen, B-CAM, is a cell surface glycoprotein that is expressed with restricted distribution pattern in normal fetal and adult tissues, and is up-regulated following malignant transformation in some cell types. We have isolated a complementary DNA for B-CAM using an expression cloning technique. The complementary DNA (EMBL accession number X80026) encodes a 588-amino acid protein which is a novel member of the immunoglobulin superfamily with a characteristic V-V-C2-C2-C2 immunoglobulin domain structure. This structure has been described previously for the human MUC18 melanoma antigen (31% amino acid identity) and chicken and rat versions of a neural adhesion molecule referred to as SC1/DM-GRASP/BEN or KG-CAM, respectively (26% amino acid identity). This homology is suggestive of a role for B-CAM in cell-cell or cell-matrix adhesion. The gene for B-CAM has been mapped by fluorescence in situ hybridization to chromosome 19q13.2-13.3.
