PZR an immunoglobulin superfamily cell surface protein. Contains two tyrosine-based inhibition motifs (ITIMs) responsible for binding of SHP-2. When phosphorylated, it can specifically bind SHP-2, blocking its translocation, and interupting its function. Treatment of several cell lines with ConA caused tyrosine phosphorylation of PZR. Two alternatively spliced isoforms have been reported. One isoform, PZR1b, lacks the ITIMs and has a dominant negative effect upon full-length PZR and its recruitment of SHP-2. Note: This description may include information from UniProtKB.
