| Outline of Final Research Achievements |
The formation of proper brain architecture requires the normal development of neuronal cells. Neurons, especially, changes its cell shape dramatically from the unpolarized to the polarized cell morphology during the neuronal differentiation. The typical hallmark in neuronal differentiation is axonogenesis and dendritogenesis. Golgi apparatus in neuron extend its size and shape; shows the extension into the apical dendrite. This golgi apparatus deployment is regulated by Reelin-Dab1 signaling. We focused on the mechanisms underlying this golgi deployment and performed the proposed research projects during past 1.5 years. Interestingly, mass-spec analysis could find the phosphorylation on GM130, a cis-Golgi protein by Reelin stimulation. This phosphorylation is on Ser300 and may contribute to the development of brain.
