Grouped By:  Matching UniProtKB accession

UniProtKB description:  DNA helicase that plays a role in DNA damage repair and genome stability (PubMed:7961977, PubMed:7527136, PubMed:8056767, PubMed:15886194, PubMed:35025765). Exhibits a magnesium- and ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction (PubMed:7527136, PubMed:8056767, PubMed:35025765, PubMed:19151156). Full-length protein unwinds forked DNA substrates, resolves Holliday junctions, and has DNA strand annealing activity (PubMed:19151156, PubMed:25831490). Plays a role in restoring regressed replication forks (PubMed:35025765). Required to restart stalled replication forks induced by abortive topoisomerase 1 and 2 lesions (PubMed:35025765). May play a role in the repair of DNA that is damaged by ultraviolet light or other mutagens (PubMed:7961977, PubMed:15886194).
