Anti-EMP2 antibody produced in rabbit (C15-1448-216)

General description

EMP2 (epithelial membrane protein 2) belongs to the family of four-transmembrane domains proteins called growth arrest-specific gene 3 (GAS-3)/peripheral myelin protein 22 (PMP22). It is a transmembrane protein, which spans the membrane four times. It is predominantly expressed in secretory endometrium, alveolar epithelium in lungs, and in eye in the retinal pigmented epithelium. This protein has three predicted N-linked glycosylation sites, two exoplasmic domains, and a short cytolsolic tail. It is a tumor suppressor gene for certain cancers such as, B-cell lymphoma.

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

EMP2 (epithelial membrane protein 2) is involved in blastocyst implantation, where it controls the surface expression and localization of integrin αvβ3. It is up-regulated in endometrioid ovarian tumors, which is associated with poor prognosis and survival. It is involved in controlling the correct trafficking of glycolipids and multiple proteins from post-Golgi endosomes to plasma membrane. It also regulates the proper trafficking of specific molecules to glycolipids-enriched lipid raft microdomains (GEMs). It interacts with and activates focal adhesion kinase (FAK) and the FAK/Src complex, which in turn facilitates collagen gel contraction. This gene is also down-regulated in nasopharyngeal carcinoma (NPC), especially in high grade cases. In NPC, it might be involved in increases tumor aggressiveness, and poor prognosis. It is highly up-regulated in triple negative breast cancer and invasive breast cancer. It might have potential as a therapeutic target for the same.

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.
