Novel mesenchymal and haematopoietic cell isoforms of the SHP-2 docking receptor, PZR: identification, molecular cloning and effects on cell migration.
SHP-2 (Src homology phosphatase type-2) is essential for haematopoietic skeletal and vascular development. Thus the identification of its binding partners is critically important. In the present study, we describe a unique monoclonal antibody, WM78, which interacts with PZR, a SHP-2 binding partner. Furthermore, we identify two novel isoforms of PZR, PZRa and PZRb, derived by differential splicing from a single gene transcription unit on human chromosome 1q24. All are type 1 transmembrane gly...Expand abstract
