    ..Overexpression of SAD-1 causes mislocalization of vesicle proteins to dendrites, suggesting that sad-1 affects axonal-dendritic polarity as well as synaptic development. ..

    ..We propose that Neurabin functions as a scaffold to facilitate SAD-1-mediated phosphorylation for substrates specific for restricting axonal fate during neuronal polarization. ..

    ..The data reveal a new and unprecedented role for synapse assembly proteins, acting as part of the newly defined CSS system, in mediating UNC-16's organelle transport regulatory function. ..

    ..These results suggest that IMPase is required in central interneurons of the mature nervous system for correct localization of synaptic components and thus for normal behavior. ..

    ..These results suggest that the LRK-1 protein kinase determines polarized sorting of SV proteins to the axons by excluding SV proteins from the dendrite-specific transport machinery in the Golgi. ..

    ..This study reports the first temporal analysis of a neural kinase activity using the chemical-genetic system. It reveals that neuronal polarity and synaptic organization have distinct temporal requirements for SAD-1. ..
  8. Kim J, Hung W, Narbonne P, Roy R, Zhen M. C. elegans STRADalpha and SAD cooperatively regulate neuronal polarity and synaptic organization. Development. 2010;137:93-102 pubmed publisher
    ..Our findings suggest that instead of a single, linear genetic pathway, STRADalpha and LKB1 regulate neuronal development through multiple effectors that are shared in some cellular contexts but distinct in others. ..

    ..Together, these results suggest that arl-8 promotes a trafficking identity for presynaptic cargoes, facilitating their efficient transport by repressing premature self-association. ..
