function:Cell surface receptor that may play a role in the innate and adaptive immune response.,PTM:Phosphorylated on tyrosine residues.,similarity:Contains 1 Ig-like V-type (immunoglobulin-like) domain.,subcellular location:Sequestered in cytoplasmic vesicles in resting platelets. Transported to the cell surface after stimulation by thrombin. Soluble fragments can be released into the serum by proteolysis.,subunit:When phosphorylated, interacts with PTPN6 (By similarity). When phosphorylated, interacts with PTPN11.,tissue specificity:Detected in platelets, monocytic leukemia and in T-cell leukemia.,
