Predicted to enable ATP-dependent activity, acting on DNA. Predicted to contribute to DNA binding activity; DNA clamp loader activity; and single-stranded DNA helicase activity. Predicted to be involved in DNA repair; DNA-dependent DNA replication; and positive regulation of DNA-directed DNA polymerase activity. Predicted to be part of Ctf18 RFC-like complex and DNA replication factor C complex. Predicted to be active in nucleus. Is expressed in central nervous system; liver; retina nuclear layer; skeletal muscle; and submandibular gland primordium. Orthologous to human RFC3 (replication factor C subunit 3).
