Neil Hunter and colleagues show that RNF212 is essential for crossing-over during mammalian meiosis and functions to couple chromosome synapsis to the formation of crossover-specific recombination complexes. They further show that selective localization of RNF212 to a subset of recombination sites is a key step in the crossover designation process that serves to stabilize meiosis-specific recombination factors at these sites.
