Summary: Enables DNA nuclease activity and four-way junction DNA binding activity. Involved in double-strand break repair. Located in cytoplasm and nucleus. Is expressed in several structures, including antennal anlage; antennal primordium; ganglia; head epidermis primordium; and mesoderm. Orthologous to human GEN1 (GEN1 Holliday junction 5' flap endonuclease). [provided by Alliance of Genome Resources, Dec 2024]
