Predicted to enable protein tyrosine phosphatase activity. Predicted to be involved in protein dephosphorylation. Predicted to act upstream of or within negative regulation of neuron projection development; peptidyl-tyrosine dephosphorylation; and positive regulation of protein localization to plasma membrane. Located in neuron projection terminus. Is expressed in several structures, including genitourinary system; liver; lung; midbrain; and spleen. Orthologous to human PTPN9 (protein tyrosine phosphatase non-receptor type 9). [provided by Alliance of Genome Resources, Apr 2022]
