Abstract: Prothymosin alpha (ProTα) and S100A13 are released from C6 glioma cells under serum- free conditions via membrane tethering mediated by Ca2+-dependent interactions between S100A13 and p40 synaptotagmin-1 (Syt-1), which is further associated with plasma membrane syntaxin-1 (Stx-1). The present study revealed that S100A13 interacted with annexin A2 (ANXA2) and this interaction was enhanced by Ca2+ and p40 Syt-1. Amlexanox (Amx) inhibited the association between S100A13 and ANXA2 in C6 glioma cells cultured under serum-free conditions in the in situ proximity ligation assay. In the absence of Amx, however, the serum-free stress results in a flop-out of ANXA2 Citation: Matsunaga, H.; Halder, through the membrane, without the extracellular release. The intracellular delivery of anti-ANXA2 S.K.; Ueda, H. Annexin A2 Flop-Out antibody blocked the serum-free stress-induced cellular loss of ProTα, S100A13, and Syt-1. -

Annexin A1 Is a New Functional Linker Between Actin Filaments and Phagosomes During Phagocytosis

Published by The Company of Biologists Ltd doi:10.1242/jcs.076208 Summary Remodelling of the actin cytoskeleton plays a key role in particle internalisation and the phagosome maturation processes. Actin- binding proteins (ABPs) are the main players in actin remodelling but the precise role of these proteins in phagocytosis needs to be clarified. Annexins, a group of ABPs, are known to be present on phagosomes. Here, we identified annexin A1 as a factor that binds to isolated latex bead phagosomes (LBPs) in the presence of Ca2+ and facilitates the F-actin–LBP interaction in vitro. In macrophages the association of endogenous annexin A1 with LBP membranes was strongly correlated with the spatial and temporal accumulation of F-actin at the LBP. Annexin A1 was found on phagocytic cups and around early phagosomes, where the F-actin was prominently concentrated. After uptake was completed, annexin A1, along with F-actin, dissociated from the nascent LBP surface. At later stages of phagocytosis annexin A1 transiently concentrated only around those LBPs that showed transient F-actin accumulation (‘actin flashing’). -

Changes in the Cytosolic Proteome of Aedes Malpighian Tubules

The cytosols of control (C) and aedeskinin-treated (T) tubules were extracted from several thousand Malpighian tubules, subjected to 2-D electrophoresis and stained for total proteins and phosphoproteins. The comparison of C and T gels was performed by gel image analysis for the change of normalized spot volumes. Spots with volumes equal to or exceeding C/T ratios of ±1.5 were robotically picked for in- gel digestion with trypsin and submitted for protein identification by nanoLC/MS/MS analysis. Identified proteins covered a wide range of biological activity. As kinin peptides are known to rapidly stimulate transepithelial secretion of electrolytes and water by Malpighian tubules, we focused on those proteins that might mediate the increase in transepithelial secretion. We found that AK- III reduces the cytosolic presence of subunits A and B of the V-type H+ ATPase, endoplasmin, calreticulin, annexin, type II regulatory subunit of protein kinase A (PKA) and rab GDP dissociation inhibitor and increases the cytosolic presence of adducin, actin, Ca2+-binding protein regucalcin/SMP30 and actin-depolymerizing factor. -

The immune complexes are deposited in the glomerular mesangium, leading to inflammation and loss of renal function, but the complete pathophysiology of the disease is not understood. Using an integrated global transcriptomic and proteomic profiling approach, we investigated the role of the mesangium in the onset and progression of IgAN. Global gene expression was investigated by microarray analysis of the glomerular compartment of renal biopsy specimens from patients with IgAN (n=19) and controls (n=22). Using curated glomerular cell type–specific genes from the published literature, we found differential expression of a much higher percentage of mesangial cell–positive standard genes than podocyte-positive standard genes in IgAN. Principal coordinate analysis of expression data revealed clear separation of patient and control samples on the basis of mesangial but not podocyte cell–positive standard genes. -

It is an abundant protein that associates with biological membranes as well as the actin cytoskeleton, and has been implicated in intracellular vesicle fusion, the organization of membrane domains, lipid rafts and membrane-cytoskeleton contacts. In addition to an intracellular role, AnxA2 has been reported to participate in processes localized to the cell surface including extracellular protease regulation and cell-cell interactions. There are many reports showing that AnxA2 is differentially expressed between normal and malignant tissue and potentially involved in tumour progression. An important aspect of AnxA2 function relates to its interaction with small Ca2+-dependent adaptor proteins called S100 proteins, which is the topic of this review. The interaction between AnxA2 and S100A10 has been very well characterized historically; more recently, other S100 proteins have been shown to interact with AnxA2 as well. The biochemical evidence for the occurrence of these protein interactions will be discussed, as well as their function. -
Structure – Function Studies of Annexin A2 & A5
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by University of Minnesota Digital Conservancy Structure – Function Studies of Annexin A2 & A5 Stephanie Schramel Swenson College of Science and Engineering University of Minnesota Duluth [email protected] Introduction: Within the cell, proteins exist to maintain the intracellular level of calcium ions (Ca2+), allowing calcium to act as a secondary messenger. Annexins are a group of these proteins located in muscle cells which bind calcium in order to bind to phospholipids in the plasma membrane. Although there are multiple forms of this protein found in humans, all contain a similar structural basis consisting of an amino-terminal head domain, a carboxyl terminal domain, and conserved structural repeats of around 70 residues. Both the calcium binding and membrane binding sites are located at the carboxyl domain. Annexins bind to negatively charged phospholipids at the cellular membranes, which differentiates them from other calcium binding proteins. Exocytosis/endocytosis, ion transport, and transport of vesicles are also processes orchestrated by these proteins.1 Specifically, annexin A2 (AnxA2) and A5 (AnxA5) are the proteins we studied. Figure 1 shows the 3-D structure of AnxA2 with calcium bound. The question we tried to understand is the mechanism for how AnxA2 and AnxA5 function at the membrane in terms of the redistribution of lipids and the effect on membrane permeability. In order to study the annexins, we grew E. coli cells that expressed our desired proteins. We then went through multiple week- long purification processes to obtain pure protein to be used for further studies. -

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in
