Background

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).

FAQs for EpCAM/TROP1 Antibody Pair (NBP2-79378). (Showing 1 - 1 of 1 FAQ).

1. I'm looking for EpCAM antibody for rat. Do you have any antibody which can use FACS?
   • We unfortunately do not have any EpCAM antibodies validated in FACS for detection of the rat protein. I am sorry for any inconvenience. I do have three products to EpCAM that can detect the rat protein. These products have been validated to detect the native rat protein, so they may work for FACS however they have not yet been tested in that particular application. If you would like to try them in your experiment you would qualify for our Innovator's Reward Program. This program was designed to help scientists with the cost of their antibodies in return for valuable information. If you decide to test an antibody in a previously untested species or application we will issue you a credit for the purchase price of the antibody in exchange for a review of your experiment using our product.
