During meiosis, paired homologous chromosomes (homologues) become linked via the synaptonemal complex (SC) and crossovers. Crossovers mediate homologue segregation and arise from self-inflicted double-strand breaks (DSBs). Here, we identify functions in homologue juxtaposition and crossing over of the proteasome, the multi-subunit protease that degrades proteins in the nucleus and cytoplasm. Without proteasome function, homologues fail to pair and instead remain associated with non-homologous chromosomes. While dispensable for non-crossover formation, a functional proteasome is required for a coordinated transition that entails SC assembly between longitudinally organized chromosome axes and stable strand exchange of crossover-designated DSBs. Remarkably, proteolytic core and regulatory proteasome particles are recruited to chromosomes by Zip3, the orthologue of mammalian E3 ligase RNF212, and SC protein Zip1 as part of an evolutionarily conserved program.
