Interference-mediated synaptonemal complex formation with embedded crossover designation.
Biological systems exhibit complex patterns at length scales ranging from the molecular to the organismic. Along chromosomes, events often occur stochastically at different positions in different nuclei but nonetheless tend to be relatively evenly spaced. Examples include replication origin firings, formation of chromatin loops along chromosome axes and, during meiosis, localization of crossove...
متن کاملThe MAP kinase pathway coordinates crossover designation with disassembly of synaptonemal complex proteins during meiosis
Asymmetric disassembly of the synaptonemal complex (SC) is crucial for proper meiotic chromosome segregation. However, the signaling mechanisms that directly regulate this process are poorly understood. Here we show that the mammalian Rho GEF homolog, ECT-2, functions through the conserved RAS/ERK MAP kinase signaling pathway in the C. elegans germline to regulate the disassembly of SC proteins...

متن کاملCrossover/Noncrossover Differentiation, Synaptonemal Complex Formation, and Regulatory Surveillance at the Leptotene/Zygotene Transition of Meiosis
Yeast mutants lacking meiotic proteins Zip1, Zip2, Zip3, Mer3, and/or Msh5 (ZMMs) were analyzed for recombination, synaptonemal complex (SC), and meiotic progression. At 33 degrees C, recombination-initiating double-strand breaks (DSBs) and noncrossover products (NCRs) form normally while formation of single-end invasion strand exchange intermediates (SEIs), double Holliday junctions, crossover...
متن کاملIpl1/Aurora B kinase coordinates synaptonemal complex disassembly with cell cycle progression and crossover formation in budding yeast meiosis.
Several protein kinases collaborate to orchestrate and integrate cellular and chromosomal events at the G2/M transition in both mitotic and meiotic cells. During the G2/M transition in meiosis, this includes the completion of crossover recombination, spindle formation, and synaptonemal complex (SC) breakdown. We identified Ipl1/Aurora B kinase as the main regulator of SC disassembly. Mutants la...
