function:May play a role in epithelial cell-cell contacts. May play a role in tumor invasiveness and metastasis formation.,PTM:O-glycosylated. The O-glycan is modified with sialic acid residues.,similarity:Belongs to the SMAGP family.,subcellular location:Predominantly on lateral parts of the membrane, at cell-cell epithelial junctions. Detected on cytoplasmic membranes in undifferentiated tumors.,tissue specificity:Detected in breast, endometrium, colon and biliary tract. Detected in polarized epithelial structures characterized by cell-cell adhesion (at protein level).,
