Predicted to enable ATP-dependent DNA/DNA annealing activity; K63-linked polyubiquitin modification-dependent protein binding activity; and endodeoxyribonuclease activity. Predicted to be involved in several processes, including DNA metabolic process; DNA rewinding; and negative regulation of DNA recombination. Predicted to be located in nucleoplasm. Predicted to be active in nuclear replication fork. Orthologous to human ZRANB3 (zinc finger RANBP2-type containing 3). [provided by Alliance of Genome Resources, Apr 2022]
