Automated description from the Alliance of Genome Resources
Exhibits protein homodimerization activity and protein tyrosine phosphatase activity. Involved in negative regulation of insulin receptor signaling pathway; regulation of mast cell activation; and transmembrane receptor protein tyrosine phosphatase signaling pathway. Localizes to the cytoplasm and plasma membrane. Is expressed in midbrain and superior colliculus. Orthologous to human PTPRE (protein tyrosine phosphatase receptor type E).
