Enables protein tyrosine kinase binding activity and protein tyrosine phosphatase activity. Acts upstream of or within several processes, including negative regulation of T cell mediated immunity; regulation of signal transduction; and transforming growth factor beta receptor signaling pathway. Predicted to be located in cytoplasm; leading edge of lamellipodium; and plasma membrane. Predicted to be part of filamentous actin. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; nose; and somite. Orthologous to human DUSP22 (dual specificity phosphatase 22).
