MSH4/MSH5 are critical components of the class I crossover (CO) machinery, which is responsible for >90% of the COs that arise in mammalian meiosis. We generated a point mutation in the ATP binding motif of Msh5, and found that mutant spermatocytes lose all COs, not just those arising from the class I pathway.
