abstract = {Generation of meiotic crossovers in many eukaryotes requires the elimination of anti-crossover activities by utilizing the Msh4?Msh5 heterodimer to block helicases. Msh4 and Msh5 have been lost from the flies Drosophila and Glossina but we identified a complex of mini-chromosome maintenance (MCM) proteins that functionally replace Msh4?Msh5. REC, an ortholog of MCM8 that is divergent in flies, interacts with MEI 217 and MEI-218, which arose from one a previously undescribed ancestral metazoan-specific MCM protein. Meiotic crossovers are reduced in Drosophila rec, mei-217, and mei-218 mutants; however, removal of the Bloom syndrome helicase ortholog restores crossovers. Thus, MCMs were co-opted into a novel complex to replace the meiotic pro-crossover function of Msh4?Msh5 in flies.}
