    Summary
    Enables 3'-5'-DNA exonuclease activity and DNA-directed DNA polymerase activity. Involved in DNA replication proofreading. Located in nucleus. Part of alpha DNA polymerase:primase complex. Is expressed in follicle cell; nurse cell; organism; and ovary. Human ortholog(s) of this gene implicated in Van Esch-O'Driscoll syndrome and X-linked reticulate pigmentary disorder. Orthologous to human POLA1 (DNA polymerase alpha 1, catalytic subunit). [provided by Alliance of Genome Resources, Dec 2024]
