An ATP-dependent DNA helicase which unwinds dsDNA with a 3′-overhang in a 3′-5′ direction (PubMed:28653661). Does not unwind more than 18 bp of dsDNA (PubMed:28653661). May modulate chromosome segregation. The N-terminal domain (residues 1-54) binds DNA Y-shaped DNA better than ss- or dsDNA (PubMed:22730300). The core helicase domain binds ssDNA (PubMed:22730300, PubMed:28653661).
