Protein kinase C-dependent phosphorylation of synaptosome-associated protein of 25 kDa at Ser187 potentiates vesicle recruitment.
Activation of protein kinase C (PKC) constitutes a key event in the upregulation of secretory strength in neurons and neurosecretory cells during extensive stimulation, presumably by speeding up vesicle supply. However, the molecular targets and their mode of action remain elusive. We studied the only PKC-dependent phosphorylation site in the neuronal soluble N-ethylmaleimide-sensitive factor a...
متن کاملEvolutionary conservation of synaptosome-associated protein 25 kDa (SNAP-25) shown by Drosophila and Torpedo cDNA clones.
The neuron-specific proteins SNAP-25 (synaptosome-associated protein 25 kDa), synaptobrevin and syntaxin, are localized to presynaptic terminals in mammals and have been found to associate with proteins involved in vesicle docking and membrane fusion. We describe here SNAP-25 cDNA clones from the fruit fly Drosophila melanogaster and the ray Torpedo marmorata. In situ hybridization showed that ...
متن کاملSynaptosomal Protein of 25 kDa (Snap25) Polymorphisms Associated with Glycemic Parameters in Type 2 Diabetes Patients
A possible role of Snap25 polymorphisms in type 2 diabetes mellitus (T2DM) was evaluated by analyzing three SNPs within intron 1 in a region known to affect the gene expression in vitro. Genomic DNA from 1019 Saudi individuals (489 confirmed T2DM and 530 controls) was genotyped for SNPs rs363039, rs363043, and rs363050 in Snap25 using the TaqMan Genotyping Assay. Significantly higher levels of ...
متن کاملDrosophila huntingtin-interacting protein 14 is a presynaptic protein required for photoreceptor synaptic transmission and expression of the palmitoylated proteins synaptosome-associated protein 25 and cysteine string protein.
Palmitoylation affects the trafficking, stability, aggregation, and/or functional activity of a substantial number of neuronal proteins. We identified mutations in dHIP14, the Drosophila homolog of the human palmitoyl transferase, Huntingtin-interacting protein 14 (HIP14). HIP14 was previously reported to localize primarily to Golgi and to palmitoylate the neuronal proteins synaptosome-associat...
متن کامل23-kDa protein associated with CD40
CD40 is a 45-kDa glycoprotein member ofthe tumor necrosis factor receptor (TNFR) family expressed on B cells, thymic epithelial cells, dendritic cells, and some carcinoma cells. The unique capacity of CD40 to trigger immunoglobulin isotype switching is dependent on the activation of protein-tyrosine kinases, yet CD40 possesses no kinase domain and no known consensus sequences for binding to pro...
