Tight control of the number and distribution of crossovers is of great importance for meiosis. Crossovers establish chiasmata, which are physical connections between homologous chromosomes that provide the tension necessary to align chromosomes on the meiotic spindle. Understanding the mechanisms underlying crossover control has been hampered by the(More)
The Wnt family of secreted proteins has been shown to have multiple roles in embryonic development. Wnt signals are thought to be propagated by binding to the cysteine-rich extracellular domain (CRD) of Frizzled, a seven-transmembrane-domain cell surface receptor. Secreted Frizzled-related proteins (generally denoted Frzb or Sfrp) possess a domain with a(More)
