Yu HG and Koshland D (2005) Chromosome morphogenesis: condensin-dependent cohesin removal during meiosis. Cell 123(3):397-407
Abstract: During meiosis, segregation of homologous chromosomes necessitates the coordination of sister chromatid cohesion, chromosome condensation, and recombination. Cohesion and condensation require the SMC complexes, cohesin and condensin, respectively. Here we use budding yeast Saccharomyces cerevisiae to show that condensin and Cdc5, a Polo-like kinase, facilitate the removal of cohesin from chromosomes prior to the onset of anaphase I when homologs segregate. This cohesin removal is critical for homolog segregation because it helps dissolve the recombination-dependent links between homologs that form during prophase I. Condensin enhances the association of Cdc5 with chromosomes and its phosphorylation of cohesin, which in turn likely stimulates cohesin removal. Condensin/Cdc5-dependent removal of cohesin underscores the potential importance of crosstalk between chromosome structural components in chromosome morphogenesis and provides a mechanism to couple chromosome morphogenesis with other meiotic events.
