| Background Information | Receptor-type tyrosine-protein phosphatase eta (UniProt: Q64455, also known as EC: 3.1.3.48, Protein-tyrosine phosphatase eta, R-PTP-eta, HPTP beta-like tyrosine phosphatase Protein-tyrosine phosphatase receptor type J, R-PTP-J, Susceptibility to colon cancer 1, CD148) is encoded by the Ptprj (also known as Byp, Scc1) gene (Gene ID: 19271) in murine species. R-PTP-eta is a monomeric, single pass type I membrane protein that is expressed at high levels in brain, kidney, spleen, and intestine; Lower expression levels are seen in liver, lung, thymus, and heart. It is also expressed at a high level in the myeloid cell line FDC-P2, and at a lower level in the pre-B lymphoid cell line WEHI-231. Fibroblast cell line NIH3T3 and the erythroid cell line F5-5 lack its expression. It is synthesized with a signal peptide (aa 1-28) that is subsequently cleaved off. The mature form has an extracellular domain (aa 29-876), a helical region (aa 877-897), a cytoplasmic domain (aa 898-1238). R-PTP-eta either dephosphorylates or contributes to the dephosphorylation of CTNND1, FLT3, PDGFRB, MET, RET, KDR, LYN, SRC, MAPK1, MAPK3, EGFR, TJP1, OCLN, PIK3R1 and PIK3R2 and plays a role in cell adhesion, migration, proliferation and differentiation. It is also involved in vascular development and ma participate in the mechanism of contact inhibition of cell growth. It has a positive effect on cell-matrix adhesion and on platelet activation and thrombosis. It can also serve as a negative regulator of cell proliferation and has a negative effect on PDGF-stimulated cell migration via dephosphorylation of PDGFR. R-PTP-eta is also involved in T cell receptor (TCR) signaling where upon TCR activation, it is up-regulated and excluded from the immunological synapses, while upon T cell-antigen presenting cells (APC) disengagement, it is no longer excluded and can dephosphorylate PLCG1 and LAT to down-regulate prolongation of signaling. |
