    Summary
    Enables 5'-3' DNA helicase activity; single-stranded DNA endodeoxyribonuclease activity; and single-stranded DNA helicase activity. Involved in DNA metabolic process. Located in nucleus. Is expressed in gonad and oocyte. Human ortholog(s) of this gene implicated in Seckel syndrome 8; autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 6; isolated growth hormone deficiency type IA; and mitochondrial myopathy. Orthologous to human DNA2 (DNA replication helicase/nuclease 2). [provided by Alliance of Genome Resources, Dec 2024]
