| Background |
Enables several functions, including heparan sulfate proteoglycan binding activity; heparin binding activity; and protein tyrosine phosphatase activity. Involved in several processes, including lymphocyte differentiation; regulation of cytokine production; and regulation of signal transduction. Acts upstream of or within several processes, including T cell activation; positive regulation of lymphocyte activation; and regulation of protein phosphorylation. Located in external side of plasma membrane; focal adhesion; and membrane raft. Is expressed in several structures, including alimentary system; cardiovascular system; hemolymphoid system; placenta; and skin. Used to study Alzheimer's disease and systemic lupus erythematosus. Human ortholog(s) of this gene implicated in multiple sclerosis; severe combined immunodeficiency; and severe combined immunodeficiency 105. Orthologous to human PTPRC (protein tyrosine phosphatase receptor type C). [provided by Alliance of Genome Resources, Jul 2025] |
