Among the ubiquitin members, ubiquitin and SUMO have been implicated in the regulation of many neurobiological processes and accordingly, dysregulation of the ubiquitin- and SUMO-system is associated with several neurological disorders, e.g. Alzheimer or Parkinson disease. In contrast, the function of other ubiquitin-like proteins in the brain, like Nedd8, remains elusive. The aim of this work was to identify and characterize the functions of neddylation in neuronal development and in the adult mammalian brain as well as to uncover cellular targets and molecular mechanisms underlying Nedd8 function. In the scope of this project, mouse models of the neddylation pathway were generated that will allow the dissection of Nedd8 functions in vivo. In summary, we describe neddylation as a new post-translational protein modification in the mammalian brain, controling neuronal development and function.
