    Summary
    Enables DNA-(apurinic or apyrimidinic site) endonuclease activity and phosphoric diester hydrolase activity. Involved in base-excision repair; embryo development; and nematode larval development. Predicted to be active in nucleus. Is expressed in hermaphrodite gonad and male gonad. Human ortholog(s) of this gene implicated in artery disease (multiple); breast cancer; female reproductive organ cancer (multiple); spina bifida; and urinary bladder cancer. Orthologous to human APEX1 (apurinic/apyrimidinic endodeoxyribonuclease 1). [provided by Alliance of Genome Resources, Dec 2024]
