Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding activity; p53 binding activity; and phosphatase activity. Predicted to be involved in several processes, including negative regulation of ERK1 and ERK2 cascade; protein dephosphorylation; and regulation of protein modification process. Located in mitochondrion. Is expressed in limb; nervous system; neural retina; and spleen. Orthologous to human DUSP26 (dual specificity phosphatase 26).
