Predicted to enable 5'-3' DNA helicase activity; RNA binding activity; and single-stranded DNA helicase activity. Predicted to be involved in RNA metabolic process; cellular response to DNA damage stimulus; and regulation of DNA metabolic process. Predicted to act upstream of or within DNA-dependent DNA replication. Predicted to be located in cytoplasm; nucleus; and site of double-strand break. Predicted to be part of DNA replication factor A complex. Predicted to be active in nucleolus. Orthologous to human HELB (DNA helicase B). [provided by Alliance of Genome Resources, Apr 2022]
