Protein Function Myelin protein zero-like protein 1 (MPZL1) is a member of the immunoglobulin superfamily, and is also a receptor of concanavalin A (ConA). 
Biochemical Properties Myelin protein zero-like protein 1 (MPZL1/PZR) is a single transmembrane glycoprotein comprised of an extracellular receptor domain and an intracellular domain with two immunoreceptor tyrosine-based inhibitory motifs (ITIMs).The phosphorylated ITIM motifs specially bind SH2 domains of a tyrosine phosphatase SHP-2/PTPN11.

Significance of PTMs Phosphorylation at Tyr-241 and Tyr-263 is required for interaction with PTPN11/SHP-2.
Additional Comments MPZL1 is upregulated in hepatocellular carcinoma (HCC) and accelerates migration of HCC cells.
