Helicases are in the spotlight of DNA metabolism and are critical for DNA repair in all domains of life. At their biochemical core, they bind and hydrolyze ATP, converting this energy to translocate unidirectionally, with different strand polarities and substrate binding specificities, along one strand of a nucleic acid. In doing so, DNA and RNA helicases separate duplex strands or remove nucleoprotein complexes, affecting DNA repair and the architecture of replication forks. In this review, we focus on recent advances on the roles and regulations of DNA helicases in homologous recombination repair, a critical pathway for mending damaged chromosomes and for ensuring genome integrity.
