PTPRE (Protein tyrosine phosphatase, receptor type, E) is a transmembrane protein consisting of a short extracellular domain and two tandemly repeated intracellular PTPase domains. It is located on chromosome 10q26 in humans. It is expressed in testis, brain, lung and lymph node. Its expression has also been observed during neuronal differentiation and in murine mammary tumour cells. It has an isoform consisting of an N-terminal catalytic, active phosphatase domain 1 (PD1).
Synonyms: Anti-Protein-tyrosine phosphatase epsilon; Anti-R-PTP-epsilon; Anti-Receptor-type tyrosine-protein phosphatase epsilon
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

Biochem Physiol Actions: PTPRE (Protein tyrosine phosphatase, receptor type, E) is associated with various signalling pathways including down regulation of insulin receptor signalling and Janus kinase (Jak)-STAT inhibition signalling pathway. It also plays an important role in the regulation of ERK1/2 pathway by emerging as a phosphatase through its catalytic activity. Study shows that it may play an accessory role in tumour development.
