ATPase that maintains genome stability by acting as a key regulator of DNA double-strand break (DSB) repair via homologous recombination (HR) (PubMed:23754376, PubMed:37256941, PubMed:37347663, PubMed:37515771, PubMed:37556550, PubMed:38286805, PubMed:38597669, PubMed:39636933, PubMed:41166468). Regulates HR by mediating disassembly of RAD51 filaments from DNA and chromatin, thereby preventing DNA damage-independent RAD51 loading and persistent DNA accumulation of RAD51 recombinases (PubMed:37256941, PubMed:37347663, PubMed:37515771, PubMed:37556550, PubMed:38286805, PubMed:38597669, PubMed:39636933, PubMed:41166468). Also regulates HR during meiosis by mediating dissociation of DMC1 filaments from DNA (By similarity). May regulate osteoblast proliferation and differentiation (By similarity). {ECO:0000250|UniProtKB:Q8BPY9, ECO:0000269|PubMed:23754376, ECO:0000269|PubMed:37256941, ECO:0000269|PubMed:37347663, ECO:0000269|PubMed:37515771, ECO:0000269|PubMed:37556550, ECO:0000269|PubMed:38286805, ECO:0000269|PubMed:38597669, ECO:0000269|PubMed:39636933, ECO:0000269|PubMed:41166468}.
