Predicted to enable non-membrane spanning protein tyrosine phosphatase activity and protein tyrosine kinase binding activity. Predicted to be involved in several processes, including cellular response to growth factor stimulus; negative regulation of focal adhesion assembly; and negative regulation of non-membrane spanning protein tyrosine kinase activity. Predicted to act upstream of or within several processes, including negative regulation of T cell mediated immunity; negative regulation of T cell receptor signaling pathway; and negative regulation of transcription by RNA polymerase II. 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. Orthologous to human DUSP22 (dual specificity phosphatase 22). [provided by Alliance of Genome Resources, Apr 2022]
