Ras-Associated, Small GTP-Binding Protein Mouse, Recombinant, E. Coli Rab3AGST-His Ras-associated, small GTP-binding protein mouse, recombinant, E. coli Cat. No. Amount Description: N-terminal tagged Rab3A is a small GTPase that belongs to the Ras PR-115 50 µg superfamily. Rab proteins play an important role in various aspects of membrane traffic, including cargo selection, vesicle budding, vesicle motility, tethering, docking, and fusion. Rab3A, a member of For in vitro use only! the Rab small G protein family, is involved in the process of Ca2+- dependent neurotransmitter release. Rab3A activity is regulated by Shipping: shipped on dry ice a GDP/GTP exchange protein (Rab3 GEP), a Rab GDP dissociation inhibitor (Rab GDI), and a GTPaseactivating protein (Rab3 GAP). Storage Conditions: store at -80 °C The Rab3A recycling is coupled with synaptic vesicle trafficking as follows: (i) GDP-Rab3A forms an inactive complex with Rab GDI and Additional Storage Conditions: avoid freeze/thaw cycles stays in the cytosol of nerve terminals. (ii) GDPRab3A released from Shelf Life: 12 months Rab GDI is converted to GTPRab3A by Rab3 GEP. (iii) GTP-Rab3A binds effector molecules, Rabphilin-3 and Rim, localized at synaptic Molecular Weight: 54 kDa vesicles and the active zone, respectively. These complexes facilitate Accession number: NM_009001 translocation and docking of the synaptic vesicles to the active zone. The GST-Tag facilitates the protein‘s application in typical GST Purity: > 90 % (SDS-PAGE) pull-down assays.

APP may be sequentially cleaved by ␤- and ␥-secretases leading to accumulation of ␤-amyloid (A␤) peptides in brains of Alzheimer’s disease patients, whereas cleavage of APP by ␣-secretases prevents A␤ generation.

The effects of covariates (including age, gender, postmortem interval, and batch effect) were controlled, and differentially expressed genes (DEGs) were identified using a linear mixed-effects model. To explore the biological processes, func- tional pathway enrichment and protein–protein interaction (PPI) network analyses were performed on the DEGs. The extended genes with PPI to the DEGs were obtained. Finally, the DEGs and the extended genes were ranked using the convergent functional genomics method. Eighty DEGs with q \ 0.1, including 67 downregulated and 13 upregulated genes, were identified. In the pathway enrichment analysis, the 80 DEGs were significantly enriched in one Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, GABAergic synapses, and 22 Gene Ontology terms. These genes were mainly involved in neuron, synaptic signaling and transmission, and vesicle metabolism. These processes are all linked to the pathological features of AD, demonstrating that the GABAergic system, neurons, and synaptic function might be affected in AD.

Abstract: Small Rab GTPases, the largest group of small monomeric GTPases, regulate vesicle traf- ficking in cells, which are integral to many cellular processes. Their role in neurological diseases, such as cancer and inflammation have been extensively studied, but their implication in kidney disease has not been researched in depth. Rab3a and its effector Rabphillin-3A (Rph3A) expression have been demonstrated to be present in the podocytes of normal kidneys of mice rats and humans, around vesicles contained in the foot processes, and they are overexpressed in diseases with proteinuria. In addition, the Rab3A knockout mice model induced profound cytoskeletal changes in podocytes of high glucose fed animals. Likewise, RphA interference in the Drosophila model produced structural Citation: Martinez-Arroyo, O.; and functional damage in nephrocytes with reduction in filtration capacities and nephrocyte number.
