Predicted to enable protein tyrosine phosphatase activity and protein tyrosine/serine/threonine phosphatase activity. Predicted to be involved in peptidyl-threonine dephosphorylation and peptidyl-tyrosine dephosphorylation. Predicted to act upstream of or within protein targeting to membrane; protein targeting to mitochondrion; and response to antibiotic. Predicted to be located in mitochondrial inner membrane; mitochondrial intermembrane space; and nucleoplasm. Predicted to be extrinsic component of mitochondrial inner membrane and intrinsic component of mitochondrial inner membrane. Is expressed in central nervous system; dorsal root ganglion; olfactory epithelium; and retina. Orthologous to human DUSP18 (dual specificity phosphatase 18).
