CD326, or Epithelial cell adhesion molecule, is a human gene encoded by EPCAM. It may also be known as: Ep-CAM; Adenocarcinoma-associated antigen; Cell surface glycoprotein Trop-1; Epithelial cell surface antigen; Epithelial glycoprotein; EGP; Epithelial glycoprotein 314; EGP314; hEGP314; KS 1/4 antigen; KSA; Major gastrointestinal tumor-associated protein GA733-2; Tumor-associated calcium signal transducer 1; CD antigen CD326; DIAR5; EGP-2; EGP40; HNPCC8; KS1/4; M4S1; MIC18; MK-1; TACSTD1; TROP1. The encoded protein has an amino acid length of 314 and a mass of 34.9 kDa. CD326 is a member of the EPCAM family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
