Additionally, EpCAM consistingof a 289-amino-acid-long extracellular domaincalled EpEX and a 26-amino-acidshort intracellular domain called EpICD, and Fong’s study[32] found that the loss ofmembranous EpICDexpression is a common event inhuman epithelial carcinomas. Here, EPCAM is linked to carcinoma.
