Multiple Interactions between Receptor Protein-tyrosine Phosphatase (RPTP) α and Membrane-distal Protein-tyrosine Phosphatase Domains of Various RPTPs

Junctional protein MAGI - 3 interacts with receptor tyrosine phosphatase β ( RPTP β ) and tyrosine - phosphorylated proteins

Receptor protein tyrosine phosphatase β (RPTPβ, also known as RPTPζ) and RPTPγ are members of a distinct group of phosphatases, characterized by the presence of carbonic-anhydrase-like (CAH) and fibronectin type III (FNIII) domains in their extracellular region (Barnea et al. In common with other receptor protein tyrosine phosphatases, RPTPβ mediates cell-cell and cell-matrix interactions and i...

Lack of association between receptor protein tyrosine phosphatase RPTP mu and cadherins

RPTP mu is a receptor-like protein tyrosine phosphatase that mediates homophilic cell-cell interactions. Surface expression of RPTP mu is restricted to cell-cell contacts and is upregulated with increasing cell density, suggesting a role for RPTP mu in contact-mediated signaling. It was recently reported (Brady-Kalnay, S.M., D.L. Rimm, and N.K. Tonks. 1995. J. Cell Biol. 130:977-986) that RPTP ...

PTPRA ( protein tyrosine phosphatase , receptor type , A )

Review on PTPRA, with data on DNA/RNA expression, on the protein encoded, and the functional importance of the gene.

Cell surface expression of receptor protein tyrosine phosphatase RPTP mu is regulated by cell-cell contact

RPTP mu is a transmembrane protein tyrosine phosphatase with an adhesion molecule-like ectodomain. It has recently been shown that RPTP mu mediates homophilic interactions when expressed in insect cells. In this study, we have examined how RPTP mu may function as a cell contact receptor in mink lung epithelial cells, which express RPTPmu endogenously, as well as in transfected 3T3 cells. We fin...
