High impact information on yps

  • One of these proteins was identified as the cold shock domain RNA-binding protein Ypsilon Schachtel (Yps), which we show binds directly to Exu and colocalizes with Exu in both the oocyte and nurse cells of the Drosophila egg chamber [1].
  • As orb, yps and spn-E encode RNA-binding proteins, they may regulate the translation of unidentified RNAs necessary for the polarisation of the microtubule cytoskeleton [2].
  • Furthermore, yps mutants partially suppress the premature cytoplasmic streaming of orb mutants [2].
  • We show that yps interacts genetically with orb, a positive regulator of oskar mRNA localization and translation [3].
  • We compare the functions of CncB to those of its vertebrate and invertebrate homologs, p45 NF-E2, Nrf and Skn-1 proteins, and suggest that the pharynx selector function of CncB is highly conserved on some branches of the evolutionary tree [4].
