Enables enzyme binding activity. Predicted to be involved in DNA repair; DNA-dependent DNA replication; and positive regulation of DNA-directed DNA polymerase activity. Predicted to be located in nucleoplasm. Predicted to be part of Ctf18 RFC-like complex; DNA replication factor C complex; and Elg1 RFC-like complex. Predicted to be active in nucleus. Orthologous to human RFC4 (replication factor C subunit 4). [provided by Alliance of Genome Resources, Apr 2022]
