| 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: | DSE (dermatan sulfate epimerase) is responsible for the epimerization of GlcUA (glucuronic acid) into IdoUA (iduronic acid) in chondroitin chains, and the conversion of IdoUA into GlcUA in dermatans. Mutation in this gene is associated with musculocontractural Ehlers-Danlos syndromes (MCEDS), which is an outcome of abnormalities in dermatan sulfate (DS) synthesis. It is up-regulated in squamous cell carcinomas, and has three different N-glycosylated isoforms. It is also overexpressed in esophagus squamous cell carcinoma (ESCC), and its inactivation leads to reduced IdaUA levels, leading to decreased tumor migration and invasiveness. It is expressed in glioma, gynecological cancer, pancreatic cancer, colorectal carcinoma, and prostate cancer. Its expression is not seen in breast cancer cells. |

| 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. |
| General description: | DSE (dermatan sulfate epimerase) was initially identified as a squamous cell carcinoma antigen, and was named SART2 (squamous cell carcinoma antigen recognized by T cells 2). This protein is composed of 958 amino acids. It resides in endoplasmic reticulum and partly in Golgi bodies, and has its transmembrane domain at its N-terminal. It has four putative N-glycosylation sites, and its catalytic site is present at the groove of two domains. This gene is present on human chromosome 6q22, has six exons, and codes for a protein with molecular weight of 100kDa. |
