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


Anti-PTPRR antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

PTPRR (Protein tyrosine phosphatase, receptor type, R) is a transmembrane protein-tyrosine phosphatase (PTP) belonging to the larger family of PTPs. It is expressed in the brain uterus, placenta, and lower gastrointestinal tract. It is associated with the cell proliferation and differentiation. It plays a vital role in embryonic development and in adult physiology. PTPRR negatively regulates the extracellular regulated kinase (ERK) signaling pathway. It is associated with a common, chronic, and recurrent mental disease, major depressive disorder (MDD). It also participates in cell metastasis through MAPK signaling pathways in the invasive cervical cancer, which proves PTPRR as a potential biomarker of invasive cervical cancer.

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 APREST72115.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
