Exhibits several functions, including phosphotyrosine residue binding activity; protein domain specific binding activity; and protein tyrosine phosphatase activity. Involved in several processes, including hemopoiesis; negative regulation of macromolecule metabolic process; and regulation of lymphocyte activation. Localizes to alpha-beta T cell receptor complex and cell-cell junction. Is expressed in several structures, including central nervous system; retina; and thymus primordium. Orthologous to human PTPN6 (protein tyrosine phosphatase non-receptor type 6).
