Receptor-type tyrosine-protein phosphatase η precursor recombinant protein epitope signature tag (PrEST)


All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project ( 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.

Biochem/physiol Actions

Receptor-type tyrosine-protein phosphatase eta is an enzyme encoded by the PTPRJ gene in humans. It is referred to as DEP1, SCC1, CD148, HPTPeta and R-PTP-ETA. It is a transmembrane protein-tyrosine phosphatase which acts as a suppressor of epithelial tumors. This gene may contribute to the mechanism of contact inhibition of cell growth. It acts as positive functional regulator in vascular cerebral arteriogenesis, involving differential platelet-derived growth factor (PDGF)-B gene expression. Haplotypes in this gene may play a role in susceptibility to Non-Hodgkin′s lymphoma (NHL), by affecting activation of this gene in B-cell lymphomas.

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.


Corresponding Antigen APREST86474.

DEP-1/PTPRJ is a transmembrane protein-tyrosine phosphatase which has been proposed as a suppressor of epithelial tumors. We have found loss of heterozygosity (LOH) of the PTPRJ gene and loss of DEP-1 protein expression in a subset of human meningiomas. RNAi-mediated...

We employed a Hidden-Markov-Model (HMM) algorithm in loss of heterozygosity (LOH) analysis of high-density single nucleotide polymorphism (SNP) array data from Non-Hodgkin's lymphoma (NHL) entities, follicular lymphoma (FL), and diffuse large B-cell lymphoma (DLBCL). This revealed a high frequency of...

cDNA encoding a receptor-like protein-tyrosine-phosphatase (PTP) termed DEP-1 was isolated from a HeLa cell library. The cDNA predicts an enzyme consisting of an extracellular segment containing eight fibronectin type III repeats, a single transmembrane segment, and a single intracellular PTP...
