Product Specifications

Immunogen

Recombinant human EpCAM/TROP1 protein (full-length and fragments) (Uniprot: P16422 )

Localization

Cell surface

Specificity

It is a cocktail of four highly specific monoclonal antibodies that recognize extracellular as well as intracellular domains of the epithelial cellular adhesion molecule (EpCAM). It is a 40-43kDa transmembrane epithelial glycoprotein, identified as epithelial specific antigen (ESA), or EpCAM. EpCAM is expressed on baso-lateral cell surface in most simple epithelia and a vast majority of carcinomas. This epithelial antigen plays an important role as a tumor-cell marker in lymph nodes from patients with esophageal carcinoma otherwise classified as node-negative. Epithelial antigen has also been suggested as a discriminator between basal cell and baso-squamous carcinomas, and squamous cell carcinoma of the skin.

Background: EpCAM/TROP1

Epithelial cell adhesion molecule (EpCAM), also known as TROP1 and CD326, is a type I transmembrane glycoprotein that plays a role in a number of cellular processes including adhesion, signaling, maintaining stemness, proliferation, migration, and invasion (1,2). The human EpCAM protein is 314 amino acids (aa) in length with a theoretical molecular weight (MW) of ~35 kDa (1,3,4). The EpCAM protein includes a signal peptide, an extracellular N-terminal domain, a thyroglobulin type-1 domain, a carboxyl-terminal domain, a single-pass transmembrane domain, and an intracellular domain (1,3). The protein is highly conserved and has approximately 81% aa sequence identity between human and mouse (5). Trophoblast cell-surface antigen 2 (TROP2) also shares ~67% aa sequence similarity with EpCAM (1,5). While both EpCAM and TROP2 are cell surface markers expressed in the epithelium, their expression levels typically do not correlate (5). EpCAM is expressed in normal epithelial tissue and elevated expression is observed in many epithelial carcinomas (1-3) Patient tumor samples with increased EpCAM expression have been associated with poor prognosis (1). Given EpCAM's elevated expression in tumors, it has become a potential target for cancer therapy approaches, including monoclonal antibody treatment and anti-EpCAM trispecific antibodies (1,5).

EpCAM functions as an intracellular signaling molecule and contributes to regulation of epithelial-to-mesenchymal (EMT) transition (4,5). EpCAM is cleaved during the process of regulated intramembrane proteolysis (RIP) (4,5). Initial cleavage occurs at the membrane via a disintegrin and metalloprotease 17 (ADAM17) which releases EpCAM's extracellular domain (EpEx) (4,5). A secondary cleavage is mediated by presenilin 2 (PSEN2) which releases EpCAM's cytoplasmic trail (EpICD) (4,5). EpICD translocates to the nucleus where it associates with beta-catenin, FHL-2, and LEF-1 and induces transcription of genes related to EMT and tumor growth (4,5). EpCAM has also been shown to regulate structure and functionality of the apical junction complex of cells through direct interaction with claudin-7 and association with E-cadherin (2,5). Loss of EpCAM disrupts adherins junction and tight junction structure and function (2).
