Glial cell line-derived neurotrophic factor (GDNF) regulates multiple aspects of spinal motoneuron (MN) development, including gene expression, target selection, survival, and synapse elimination, and mice lacking either GDNF or its receptors GDNF family receptor alpha1 (GFRalpha1) and Ret exhibit a 25% reduction of lumbar MNs at postnatal day 0 (P0).(More)
To elucidate the role of 3-phosphoinositide-dependent protein kinase-1 (PDK1) in cellular signaling, we constructed and expressed a pseudosubstrate of PDK1, designated as deltaAL-PIF, and characterized its properties in cultured cells. deltaAL-PIF consists of two fused proteins of the protein kinase Cdelta (deltaPKC) activation loop (deltaAL) and(More)
Cytochrome P-450 is involved in the oxidative metabolism of a broad range of substrates. We have made a chimeric construct, pSN002, containing the cDNA for rabbit liver cytochrome P-450 (IIC14) under the control of the TR2' promoter for mannopine synthase in the Agrobacterium Ti plasmid. Nicotiana tabacum was transformed with Agrobacterium tumefaciens(More)
PICK1 is a protein which was initially identified as a protein kinase Calpha (alphaPKC) binding protein using the yeast two-hybrid system. In addition to alphaPKC, the PICK1 complex binds to and regulates various transmembrane proteins including receptors and transporters. However, it has not been clarified when and where PICK1 binds to alphaPKC. We(More)
To elucidate spatial and temporal profiles of the protein kinase C (PKC) activation in relation to neuronal functions including synaptic plasticity, we tried to detect PKC translocation in living brain slices. We first developed brain region-specific and inducible gammaPKC-GFP transgenic mice using a tetracycline (tet)-regulated system. In the transgenic(More)
We examined the precise intracellular translocation of gamma subtype of protein kinase C (gammaPKC) after various extracellular stimuli using confocal laser-scanning fluorescent microscopy (CLSM) and immunogold electron microscopy. By CLSM, treatment with 12-O-tetradecanoylphorbol-13-acetate (TPA) resulted in a slow and irreversible accumulation of green(More)
We examined the precise intracellular translocation of g subtype of protein kinase C (gPKC) after various extracellular stimuli using confocal laser-scanning fluorescent microscopy (CLSM) and immunogold electron microscopy. By CLSM, treatment with 12-O-tetradecanoylphorbol-13-acetate (TPA) resulted in a slow and irreversible accumulation of green(More)
