DNA strand displacement, strand annealing and strand swapping by the Drosophila Bloom's syndrome helicase [PDF]

Nucleic Acids Research, 2007
Genetic analysis of the Drosophila Bloom's syndrome helicase homolog (mus309/DmBLM) indicates that DmBLM is required for the synthesis-dependent strand annealing (SDSA) pathway of homologous recombination.
