Predicted to enable histone H2AXY142 phosphatase activity; non-membrane spanning protein tyrosine phosphatase activity; and protein tyrosine phosphatase activity, metal-dependent. Predicted to be located in membrane. Human ortholog(s) of this gene implicated in colorectal cancer and esophagus squamous cell carcinoma. Orthologous to human PTPRT (protein tyrosine phosphatase receptor type T).
