Predicted to enable histone H2AXY142 phosphatase activity; non-membrane spanning protein tyrosine phosphatase activity; and protein tyrosine phosphatase activity, metal-dependent. Predicted to act upstream of or within cell division and positive regulation of cell cycle G2/M phase transition. Is expressed in ectoderm; mesoderm; and visual system. Human ortholog(s) of this gene implicated in cervical cancer; prostate cancer; and urinary bladder cancer. Orthologous to human CDC25A (cell division cycle 25A).
