General description

Epithelial cell adhesion molecule (EpCAM) gene, also referred to as TACSTD (tumor-associated calcium signal transducer) 1, is mapped to human chromosome 2p21, a region composed of the mutS homolog 2 (MSH2) and mutS homolog 6 (MSH6) DNA mismatch repair genes. The gene codes for a membrane-associated glycoprotein expressed in epithelial cells of different organs.


Tumor-associated calcium signal transducer 1 Precursor recombinant protein epitope signature tag (PrEST)


Anti-EPCAM antibody produced in rabbit has been used in proximity ligation assay to study the interaction between EpCAM and AGR2 (anterior gradient-2 ) proteins.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Biochem/physiol Actions

Epithelial cell adhesion molecule (EpCAM) might function as a hepatic stem/progenitor cell-specific marker. EpCAM is an oncogene activated by deliverance of its intracellular domain, which is involved in transducing signals into the cell nucleus by associating with elements of the wnt pathway. Since the epithelial cell adhesion molecule (EpCAM) is highly expressed in premalignant hepatic tissues and in a subset of hepatocellular carcinoma (HCC), it might act as an early biomarker of hepatocellular carcinoma (HCC). EpCAM gene mutation leads to a rare autosomal recessive diarrheal disorder in infants called congenital tufting enteropathy (CTE). Like other cell adhesion molecules, EpCAM plays a crucial role in cell-cell interaction and it is also associated with tight junction protein, like claudin-7. Experimental studies hypothesize that EpCAM is involved in normal intestinal and crypt villus axis development .

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
• Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)
