The function of ENSG00000160957 (RECQL4, RecQ like helicase 4) is as follows. 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). {ECO:0000269|PubMed:15317757, ECO:0000269|PubMed:22730300, ECO:0000269|PubMed:28653661}.
