Enables RNA binding activity and protein tyrosine phosphatase activity. Involved in mesodermal cell fate specification; positive regulation of transcription, DNA-templated; and protein sumoylation. Acts upstream of or within several processes, including animal organ development; positive regulation of cell population proliferation; and regulation of signal transduction. Located in cytoplasm and nucleus. Part of protein-DNA complex. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Used to study branchiootorenal syndrome. Human ortholog(s) of this gene implicated in branchiootorenal syndrome and branchiootorenal syndrome 1. Orthologous to human EYA1 (EYA transcriptional coactivator and phosphatase 1).
