Enables chromatin binding activity; protein tyrosine phosphatase activity; and protein tyrosine/serine/threonine phosphatase activity. Acts upstream of or within protein dephosphorylation. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including branchial arch; genitourinary system; limb bud; rhombomere; and sensory organ. Orthologous to human EYA3 (EYA transcriptional coactivator and phosphatase 3). [provided by Alliance of Genome Resources, Apr 2022]
