Component of the fork protection machinery required to protect stalled/damaged replication forks from uncontrolled DNA2-dependent resection. Acts by stabilizing RAD51 at stalled replication forks and protecting RAD51 nucleofilaments from the antirecombinogenic activities of FBH1 and BLM (, ). Does not regulate spindle orientation .
Subcellular locations: Chromosome
Localizes at replication forks: following DNA damage, localizes to damaged replication forks undergoing resection.
