    text
  • synapsis of meiotic chromosomes
  • localizes to unsynapsed meiotic chromosomes
  • basic FUNCTION
  • probable constituent of the synaptonemal complex during meiosis
  • regulate interactions between homologous chromosomes (homologs) during meiosis in a wide range of eukaryotes
  • meiotic HORMA-domain proteins are required to direct double-strand breaks repair towards homologues
  • involvement of meiotic HORMA-domain proteins in the regulation of homologue interactions is conserved in mammals
  • HORMAD2-dependent recruitment of ATR to unsynapsed chromosome axes constitutes a mechanism for the surveillance of asynapsis
  • SYCP3 and the SYCP2 C terminus, form a compact core around which cohesin complexes, HORMADs, HORMAD1, and HORMAD2 and the N terminus of SYCP2 are arrayed

    protein
  • interact with RED1
  • HORMAD2-dependent quality control mechanism that recognizes unsynapsis and recruits ATR activity during mammalian meiosis
  • HORMAD1 binds a motif found both at its own C terminus and at that of HORMAD2, indicating that this mode of intermolecular association is a conserved feature of meiotic chromosome structure
  • TRIP13 regulates both MAD2L1 and meiotic HORMAD1, HORMAD2 by disassembling these HORMA domain-closure motif complexes
  • TRIP13 is a negative regulator of the HORMA proteins, including HORMAD1 and HORMAD2
