Predicted to enable protein serine/threonine phosphatase activity and protein tyrosine phosphatase activity. Acts upstream of or within cilium assembly. Located in centrosome and spindle pole. Is expressed in Kupffer's vesicle; forerunner cell group; nervous system; neural tube; and pronephric duct. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 32. Orthologous to human CDC14A (cell division cycle 14A).
