Name :
Human CD326/EPCAM Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
EPCAM (Epithelial Cellular Adhesion Molecule), also known as CD326, EGP, KS1/4, KSA, gp40, GA7332, 171A, MIC18 and TROP-1, is a single-pass type I transmembrane glycoprotein. It is composed of a 242 amino acid (aa) extracellular domain (ECD) with 2 EGF-like repeats, a transmembrane domain, and a 26 aa cytoplasmic domain. EPCAM is expressed on most normal epithelial cells and functions as a homotypic calcium-independent cell adhesion molecule. Homophilic adhesion via EpCAM requires the interaction of both EGF-like repeats, with the first EGF-like repeat mediating reciprocal interaction between EpCAM molecules on opposing cells, while the second repeat is involved in lateral interaction of EpCAM. Lateral interaction of EpCAM lead to the formation of dimers and tetramers. EPCAM may act as a physical homophilic interaction molecule at the mucosal epithelium for providing immunological barrier as a first line of defense against mucosal infection. It also plays a role in embryonic stem cells proliferation and differentiation. EpCAM expression has been found to increase in actively proliferating epithelia tissues and during adult liver regeneration. EpCAM expression is increased in human malignant neoplasias, with most carcinoma expressing EpCAM. Mutations in this gene result in congenital tufting enteropathy. EPCAM is a target for immunotherapy treatment of human carcinomas.

Construct Details :
The recombinant human EPCAM-Fc fusion is expressed as a 470 amino acid protein consisting of Gln24 – Lys265 region of EPCAM (UniProt accession #P16422) and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions (see the gel image inserted).
