Automated description from the Alliance of Genome Resources
Exhibits STAT family protein binding activity and protein tyrosine phosphatase activity. Involved in several processes, including hemopoiesis; negative regulation of signal transduction; and positive regulation of response to endoplasmic reticulum stress. Localizes to the nucleus. Predicted to colocalize with the plasma membrane. Is expressed in several structures, including genitourinary system; heart; hemolymphoid system gland; lower jaw; and midbrain. Orthologous to human PTPN2 (protein tyrosine phosphatase non-receptor type 2).
