  • Due to this late arrival, researchers from Australia can participate as external collaborators in proposals submitted to this call under specific conditions. (neurodegenerationresearch.eu)
  • The specific conditions for researchers in Australia can be found on the " Specific regulations " page of the call. (neurodegenerationresearch.eu)
  • Cytoplasmic dynein, found in all animal cells and possibly plant cells as well, performs functions necessary for cell survival such as organelle transport and centrosome assembly. (wikipedia.org)
  • Reducing equivalents produced in the Krebs cycle and in the beta-oxidation spirals are passed along a series of protein complexes embedded in the inner mitochondrial membrane (the electron transport chain). (medlink.com)
  • reveal how Rho GTPase and the actin-binding protein Shroom combine to regulate the localization of Rho kinase and actomyosin contractility during axis elongation. (scivee.tv)
  • Collectively, these are called an "axoneme", This figure shows a microtubule (top panel) in surface view and in cross section (lower left hand panel). (cytochemistry.net)
  • The differences observed in the post-powerstroke conformations of different dynein isoforms may be due to spatial constraints between the complexes in the axoneme or to intrinsically different functions of the dyneins. (researchensemble.com)
  • The release of digestive enzymes and the subsequent steps are called the acrosomal reaction and it elicits a response from the egg membranes as well. (tutordale.com)
