Efficient synaptic transmission requires the apposition of neurotransmitter release sites opposite clusters of postsynaptic neurotransmitter receptors. Transmitter is released at active zones, which are composed of a large complex of proteins necessary for synaptic development and function. Many active zone proteins have been identified, but little is known(More)
Mushroom bodies (MBs) are the centers for olfactory associative learning and elementary cognitive functions in the Drosophila brain. As a way to systematically elucidate genes preferentially expressed in MBs, we have analyzed genome-wide alterations in transcript profiles associated with MB ablation by hydroxyurea. We selected 100 genes based on microarray(More)
Disrupted-in-schizophrenia-1 (DISC1) is one of major susceptibility factors for a wide range of mental illnesses, including schizophrenia, bipolar disorder, major depression and autism spectrum conditions. DISC1 is located in several subcellular domains, such as the centrosome and the nucleus, and interacts with various proteins, including NudE-like(More)
Axonal transport mediated by microtubule-dependent motors is vital for neuronal function and viability. Selective sets of cargoes, including macromolecules and organelles, are transported long range along axons to specific destinations. Despite intensive studies focusing on the motor machinery, the regulatory mechanisms that control motor-cargo assembly are(More)
BACKGROUND Members of the evolutionary conserved Ser/Thr kinase Unc-51 family are key regulatory proteins that control neural development in both vertebrates and invertebrates. Previous studies have suggested diverse functions for the Unc-51 protein, including axonal elongation, growth cone guidance, and synaptic vesicle transport. METHODOLOGY/PRINCIPAL(More)
Originally found in a Scottish family with diverse mental disorders, the DISC1 protein has been characterized as an intracellular scaffold protein that associates with diverse binding partners in neural development. To explore its functions in a genetically tractable system, we expressed the human DISC1 in fruit flies (Drosophila melanogaster). As in(More)
The neuroprotective effects of a novel synthetic compound, M50463, have been determined by using embryonic rat neocortical neurons in various culture conditions. M50463 was initially characterized as a potent specific ligand for a voltage-dependent sodium channel by radioligand binding studies. In fact, M50463 inhibited neuronal cell death induced by(More)
Polyclonal antibody against Ca2+/calmodulin-dependent protein kinase V (CaM kinase V) was prepared from guinea pigs immunized with synthetic polypeptide, based on the partial amino acid sequence of the rat brain enzyme. Immunoblot analysis of purified CaM kinase V revealed two immunoreactive bands with a molecular mass of 41 kDa and minor 40 kDa,(More)
