Abstract:
Small heat shock proteins (sHSPs) have been demonstrated to interact with lipids and modulate the physical state of membranes across species. Through these interactions, sHSPs contribute to the maintenance of membrane integrity. HSPB1 is a major sHSP in mammals, but its lipid interaction profile has so far been unexplored. In this study, we characterized the interaction between HSPB1 and phospholipids. HSPB1 not only associated with membranes via membrane-forming lipids, but also showed a strong affinity towards highly fluid membranes. It participated in the modulation of the physical properties of the interacting membranes by altering rotational and lateral lipid mobility. In addition, the in vivo expression of HSPB1 greatly affected the phase behavior of the plasma membrane under membrane fluidizing stress conditions. In light of our current findings, we propose a new function for HSPB1 as a membrane chaperone.

Abstract:
A major part of membrane function is conducted by proteins, both integral and peripheral. Peripheral membrane proteins temporarily adhere to biological membranes, either to the lipid bilayer or to integral membrane proteins with noncovalent interactions. The aim of this study was to construct and analyze the interactions of the human plasma membrane peripheral proteins (peripherome hereinafter). For this purpose, we collected a dataset of peripheral proteins of the human plasma membrane. We also collected a dataset of experimentally verified interactions for these proteins. The interaction network created from this dataset has been visualized using Cytoscape. We grouped the proteins based on their subcellular location and clustered them using the MCL algorithm in order to detect functional modules. Moreover, functional and graph theory based analyses have been performed to assess biological features of the network. Interaction data with drug molecules show that ~10% of peripheral membrane proteins are targets for approved drugs, suggesting their potential implications in disease. In conclusion, we reveal novel features and properties regarding the protein-protein interaction network created by peripheral proteins of the human plasma membrane.

Abstract:
Voltage-activated ion channels are essential for electrical signaling, yet the mechanism of voltage sensing remains under intense investigation. The voltage-sensor paddle is a crucial structural motif in voltage-activated potassium (Kv) channels that has been proposed to move at the protein–lipid interface in response to changes in membrane voltage. Here we explore whether tarantula toxins like hanatoxin and SGTx1 inhibit Kv channels by interacting with paddle motifs within the membrane. We find that these toxins can partition into membranes under physiologically relevant conditions, but that the toxin–membrane interaction is not sufficient to inhibit Kv channels. From mutagenesis studies we identify regions of the toxin involved in binding to the paddle motif, and those important for interacting with membranes. Modification of membranes with sphingomyelinase D dramatically alters the stability of the toxin–channel complex, suggesting that tarantula toxins interact with paddle motifs within the membrane and that they are sensitive detectors of lipid–channel interactions.

Abstract:
Annexin A2 (AnxA2) is a cytosolic Ca2+ regulated membrane binding protein that can induce lipid domain formation and plays a role in exocytosis and endocytosis. To better understand the mode of annexin-membrane interaction, we analyzed membrane-bound AnxA2 assemblies by employing a novel 3-armed chemical crosslinker and specific AnxA2 mutant proteins. Our data show that AnxA2 forms crosslinkable oligomers upon binding to membranes containing negatively charged phospholipids. AnxA2 mutants with amino acid substitutions in residues predicted to be involved in lateral protein–protein interaction show compromised oligomer formation, albeit still being capable of binding to negatively charged membranes in the presence of Ca2+. These results suggest that lateral protein–protein interactions are involved in the formation of AnxA2 clusters on a biological membrane.

Abstract:
This study examined the behavior and penetration mechanisms of typical phenolic (benzoic) acids, which determine their observed penetration rates during membrane separation, focusing on the influence of electrostatic and hydrophobic solute/membrane interactions. To understand the effects of hydrophobicity and electrostatic interaction on membrane filtration, the observed penetration of five structurally similar phenolic acids was compared with regenerated cellulose (RC) and polyamide (PA) membranes at different solute concentrations and solution pHs. Variation partitioning analysis (VPA) was performed to calculate the relative contributions of electrostatic and hydrophobic effects. The penetration of phenolic acids was mainly influenced by the electrostatic interaction, with salicylic acid having the highest penetration. Penetration of phenolic acids through the PA membrane decreased from 98% at pH 3.0 to 30–50% at pH 7.4, indicating the dominance of the electrostatic interaction. Moreover, based on its hydrophobicity and greater surface charge, the PA membrane could separate binary mixtures of protocatechuic/salicylic acid and 4-hydroxybenzoic/salicylic acid at pH 9.0, with separation factors of 1.81 and 1.78, respectively. These results provide a greater understanding of solute/membrane interactions and their effect on the penetration of phenolic acids through polymeric ultrafiltration membranes.

Abstract:
L'objet de cette thèse est d'étudier les interactions entre inclusions transmembranaires imposant un excès d'épaisseur en utilisant un modèle élastique décrivant les membranes au niveau de leur épaisseur. Dans un premier temps, je montre que ce modèle généralise bien les précédents en prenant en compte toutes les constantes physiques possibles. J'ajoute ensuite une condition d'ancrage au bord de l'inclusion qui peut induire ou non une pente préférentielle. Je m'assure que les résultats trouvés dans le cadre de mon modèle rejoignent le précédent pour une seule inclusion dans deux cas limites. Dans un deuxième temps, je développe une méthode de calcul multipolaire me permettant d'envisager des calculs de la forme d'une membrane où plusieurs inclusions sont présentes. Je donne les solutions générales de ce modèle et donne une manière de déterminer la solution dans le cas où deux inclusions sont présentes dans une membrane de taille infinie. Enfin, je donne pour une bicouche lipidique typique certaines courbes de profil et d'énergie d'interaction attendues. Je compare mes résultats à des expériences de Constantin à l'aide d'un algorithme de traitement reposant sur l'équation d'Ornstein-Zernike et une relation de fermeture. Le premier système "C12E5 + gramicidine", dont la membrane est constituée de surfactants, me permet de faire concorder le modèle théorique avec les expériences et je donne ainsi pour celui-ci les premières mesures de paramètres physiques nouveaux. Le deuxième système "DLPC + gramicidine" donne un moins bon accord entre la théorie et les expériences mais je donne une nouvelle piste de traitement afin de donner des estimations pour ce système
The present thesis is a study of interactions between transmembrane proteins inducing a hydrophobic mismatch with an elastic model describing the membranes at the scale of their thickness. I begin by showing that this model generalizes the precedent ones found in litterature by taking in account every possible physical constants. I add also an anchoring term at the edge of the inclusion that can induce a preferential slope. I verify that the results found with this addition is what was found previously with one inclusion in a membrane in two différent cases. Next, I develop a multipolar computation method that allows me to compute the shape of a membrane where several inclusions are presents. I give the general solutions of this model and gives an algorithm in the case where two inclusions are present in an infinite membrane. Then, I give the expected profile and the interaction energies for a typical lipidic bilayer. I compare my results to experiments performed by Constantin with an algorithm using Omstein-Zernike equation and closure relations. The first system "C12E5 + gramicidin", where the membrane is made of surfactant, gives good agreement between the theory and the experiments and allows me to give a first measurement for new physical parameters. The second system "DLPC + gramicidin" does not allow such an agreement between the theory and the experiments but I give a new lead which may give a measurement for this system

Abstract:
The aim of the thesis project was to examine what form(s) of Amyloid beta (Aβ) (25-­‐35) peptide interact with phospholipids in vitro and the implications of this for the mechanism of Alzheimer’s Diseases (AD). The mechanism of AD is thought to involve protein folding and misfolding. An increasing amount of evidence has shown that protein misfolding plays an important role in the biological and pathological processes of AD. Although seen as the biomedical markers of those diseases, the roles of amyloid aggregates themselves are still not fully understood. Whether the aggregates, or the monomer, or some other intermediates of Aβ cause AD is still unknown. In order to investigate the membrane-­‐interaction of Aβ and its implications for AD, two forms of Aβ, namely levorotary and dextrorotary (L-­‐ and D-­‐) Aβ isomers were used. Evidence has shown that L-­‐ and D-­‐ peptide can each form aggregates in a humid environment. However, when mixed together, L-­‐ and D-­‐ peptides tend not to form any aggregates. Using the mixtures of L-­‐ and D-­‐ peptides at different proportions and as well as using L-­‐ and D-­‐ alone can help us to determine the toxic form of Aβ. Phospholipids have been used to mimic membrane bilayers. Biological membranes in vivo are a complicated system. They contain three types of lipids, namely phospholipids, glycolipids, and steroids. Different types of cells and different membranes have different proportions of those lipids. Studying the interaction between Aβ and membranes in vivo can be extremely difficult. Artificial membranes, which only contains one kind of lipids, on the other hand, are a useful tool for the study of molecular interactions. Phospholipids are the most abundant type of membrane lipid and thus that can be seen as representative of cell membranes. The interactions of Aβ and different kinds of phospholipids have been investigated in this project. This thesis discusses the secondary structure of Aβ in different environment, the interaction between Aβ and phospholipids at the air-­‐water surface, and the location of Aβ in membranes during the interaction. The study provides useful information of the mechanisms and the origin of AD. At the end of the thesis, a discussion chapter analyses the difficulties of studying Aβ and AD and the potentials and inadequacies of this research.

Abstract:
La membrane plasmique de la cellule est composée de lipides et interagit notamment avec le squelette de la cellule (le cytosquelette), par l'intermédiaire de protéines d'ancrages et de lipides clefs qui jouent un rôle spécifique dans certains types d'interactions. Parmi les protéines intervenant dans l'ancrage direct de la membrane plasmique au cytosquelette, des protéines de la famille des ERM (Ezrine, Radixine, Moésine) peuvent interagir spécifiquement avec un lipide, le phosphatidylinositol (4,5) biphosphate (PiP2), d'une part et avec l'actine du cytosquelette d'autre part. Dans le but de comprendre les interactions entre membrane plasmique et cytosquelette, nous avons réalisé des expériences in vitro sur des systèmes comportant un nombre minimal de constituants : des vésicules géantes (GUV) contenant du PiP2, de l'ezrine recombinante et de l'actine purifiée. Nous avons mis en évidence que la liaison au PiP2 induit des changements conformationnels de l'ezrine. L'ezrine est alors capable d'interagir avec les filaments d'actine. Nous avons caractérisé quantitativement l'incorporation de PiP2 dans la membrane de vésicule géantes, et montré que l'interaction de l'ezrine avec les vésicule géante contenant du PiP2, induit un partitionnement du lipide dans la bicouche lipidique et conduit à la formation d'agrégats de PiP2 et d'ezrine sur la membrane. La connaissance des effets de l'ezrine sur les membranes contenant du PiP2 et la connaissance des différents mécanismes se produisant lors des interactions permettra de définir plus précisément le rôle de l'ezrine in cellulo
The plasma membrane is composed of several different lipids and can interact directly with the actin cytoskeleton via specific lipids and linker proteins. Among these is the ERM (Ezrin, Radixin, Moesin) family of proteins, which is involved in the direct linkage of the membrane to the actin cytoskeleton via a phosphatidylinositol (4,5) biphosphate (PiP2) lipid binding site. Our aim is to understand the interactions between these proteins and PiP2 using in vitro simplifed biomimetic systems like giant unilamellar vesicles (GUV) containing PiP2. We showed that a conformational change of ezrin occur when the protein binds to PiP2, this conformational change allowing ezrin to bind to actin filaments. We have characterized quantitatively the incorporation of PIP2 in the membrane of giant vesicles, and showed that the interaction of ezrin with GUV induce a partitioning of the lipid within the membrane as well as ezrin aggregates on the membrane. Likewise, ezrin oligomers were observed only in the presence of PiP2. A better understanding of the interplay between ezrin, PIP2-containing membranes and actin will help to get a better view of the role of ezrin in cellulo

Abstract:
Multinuclear magnetic resonance spectroscopy in conjunction with lanthanide shift reagents was used to investigate the interaction of unilamellar phospholipid vesicles with membrane active substances. The regulation of ion channels by lipids such as the phosphatidic acids was investigated using 1H-NMR and small phospholipid vesicles. Transport across lipid vesicles in the presence of the ionophores alamethicin, melittin and nystatin was monitored using the lanthanide probe ion Pr3+. Channel characteristics were found to be dependent upon molecular interactions between the lipid and the individual ionophores. The results were discussed in terms of the phosphatidylinositol effect. The NMR technique provided methods whereby intervesicle ionophore exchange was studied. The results revealed that ionophore exchange between vesicles, the mechanism of exchange and the rate of ion conduction were dependent upon the initial environment of the ionophore and also the lipid composition of the vesicle. The modulation of a variety of mechanisms of channel-mediated transport across small phospholipid vesicles by a range of general anaesthetics were investigated using 1H-NMR. Membrane permeability was found to be inhibited by inhalation anaesthetics independently of the channel system or lipid composition used. The results indicated the importance of hydrogen bonding as an explanation of the observed inhibition. 19F-NMR was used to monitor signals from the fluorinated anaesthetics themselves, the results providing information on the disposition of the anaesthetics within the bilayer. 23Na + and 7Li transport across large vesicles was monitored using 23Na+ and 7Li+-NMR. The effect of the general anaesthetics on ion transport was found to be dependent upon the ionophore and the type of metal ions present in the vesicular solution, further suggesting the importance of hydrophilic interactions of the anaesthetics. Finally, 31P-NMR was used to show the inhibition by general anaesthetics of the hydrolysis of glucose-6-phosphate by the enzyme glucose-6-phosphatase which further supported the above conclusions on anaesthetic action.

Abstract:
Pulsed Electric Fields (PEF) allow non-thermal pasteurization and sterilization of liquids, involving the application of high intensity electric field pulses (20-80 kV/cm) of short duration (1-10 microseconds). The electric field interacts with microorganisms at the level of plasma membrane, through the mechanism of electroporation, but, although many theories have been proposed to describe this phenomenon, a satisfactory explanation has not been found yet. An extensive description of the state of the art of the knowledge on this field is given, along with the current research needs and the main obstacles to a wide diffusion of PEF applications. The time course of cell transmembrane voltage is studied, developing an analytical expression for planar, spherical, cylindrical and prolate spheroidal membranes, with the aim to evaluate the charging time constants and the steady state intensity upon variation of treatment conditions. The results of this approach are used to investigate the impact of the electric field in rod-like bacteria. The electric field distribution in test chamber is studied by means of computer simulations for various electrode geometries, optimizing the shape for intensity and uniformity of electric field. The impact on PEF treatment of a normal distribution of cell dimensions in a microbial population and the rotational movement of bacteria inside treatment chambers are also investigated. Computer simulations are used to obtain a possible explanation to the deviations from first order inactivation kinetics, and to the intrinsic variability of microbial laboratory results. PEF inactivation experiments of Escherichia Coli are carried out in a test system under different conditions of treatment duration and microbial concentration. Inactivation kinetics is compared to theories of electroporation and computer simulations previously carried out. Experimental evidence of a variation in the effectiveness of PEF as a function of bacterial concentration is discovered and a possible explanation proposed. The application of high permittivity ceramics materials to PEF is also studied, with the aim of increasing the volumes of treatment chambers, improving the duration of electrodes, and allowing the use of the most energy efficient square wave pulses to large volumes of liquid. These materials can also be used to test the possibility of a relation between energy deposited in treatment chambers and microbial inactivation, in order to acquire more insight on the interaction between Pulsed Electric Fields and cell membranes. A novel chamber is prepared with the use of a high permittivity non-toxic material (Sodium Potassium Niobate) and it is ready to be tested in PEF applications.

Abstract:
Most integrated energy system (IES) optimization frameworks employ the price-taker approximation, which ignores important interactions with the market and can result in overestimated economic values. In this work, we propose a machine learning surrogate-assisted optimization framework to quantify IES/market interactions and thus go beyond price-taker. We use time series clustering to generate representative IES operation profiles for the optimization problem and use machine learning surrogate models to predict the IES/market interaction. We quantify the accuracy of the time series clustering and surrogate models in a case study to optimally retrofit a nuclear power plant with a polymer electrolyte membrane electrolyzer to co-produce electricity and hydrogen.

Abstract:
Applications of nanoparticles in the bio-medical field like nano-medicine, molecular imaging probes, fluorescence marker, gene carriers, are developing quickly owing to the unique characteristics of nanoparticles. Among these applications, the interaction of nano-particles with the living cells is of critical importance. The complex chemical properties and biological activities of the particles bring about undesirable cytotoxic potentials and special cell internalization. According to previous studies, the cell uptake kinetics of nanoparticles mainly depend on the concentration difference between extracellular and intracellular nanoparticles, the surface electric charge of the nanoparticle, and the active transport of the cell. For example, Ginzburg’s thermodynamic simulation and Park’s three-dimensional phase-field model quantitatively explain the transitions in membrane morphology after exposure to nanoparticles with different surface charge, respectively. However, recent studies have shown that the gold nanoparticles coated with hydrophilic and hydrophobic functional groups with the same concentration but in different orders, completely exhibit quite different intrusion ability at 4°C when the active transport of the cell is greatly inhibited. The results suggest that the interaction energy of nanoparticles and cell membranes may be another driving force for the nanopartcles’ mass transfer across the cell membrane. Thus, in this paper, the interaction energy of the differently coated nanoparticles (P) with cell membrane (M) in water (W) is studied theoretically and results are used to explain the former experimental findings.

Abstract:
One of the most important biological components is lipid nanobio membrane. The lipid membranes of alive cells and their mechanical properties play an important role in biophysical investigations. Some proteins affect the shape and properties of the nanobio membrane while interacting with it. In this study a multiscale approach is experienced: first a 100ns all atom (fine-grained) molecular dynamics simulation is done to investigate the binding of CTX A3, a protein from snake venom, to a phosphatidylcholine lipid bilayer, second, a 5 micro seconds coarse-grained molecular dynamics simulation is carried out to compute the pressure tensor, lateral pressure, surface tension, and first moment of lateral pressure. Our simulations reveal that the insertion of CTX A3 into one monolayer results in an asymmetrical change in the lateral pressure and distribution of surface tension of the individual bilayer leaflets. The relative variation in the surface tension of the two monolayers as a result of a change in the contribution of the various intermolecular forces may be expressed morphologically and lead to deformation of the lipid membrane.

Abstract:
The U.S. team studied the role of cations and pH on thermolabile (TL-PE) and thermostable (TS-PE), permeation in ultrafiltration (UF) membranes, affinity to ion exchange membranes, mechanism of cation and pH activation, and effect on PE stability. An optimum pH and cation concentration exists for activity and UF permeation, which is specific for each cation type. Incomplete release of PE from a pectin complex resulted in low PE binding to cationic and anionic membranes. Incubation of PE at low pH increases the surface hydrophobicity, especially TL-PE, but the secondary structure of TL-PE is not greatly affected. The Israeli team showed that stable cloud colloidal constituents flocculate following the conversion of soluble to insoluble biopolymers. First, formation of pectic acid by pectinesterase activity is followed by the formation of calcium pectate gel. This process initiates a myriad of poorly defined reactions that result in juice clarification. Second, protein coagulation by heat resulted in flocculation of proteinacous bound cloud constituents, particularly after enzymatic pectin degradation. Pectinesterase activity is proposed to be an indirect cause for clarification; whereas binding of cloud constituents is the primary event in clarification by pectate gel and coagulated proteins. Understanding the mechanism of interaction of protein and pectic polymers is key to understanding cloud instability. Based on the above, it was hypothesized that the structure of pectin-protein coagulates plays a key role in cloud instability.

Abstract:
The report contains three parts which summarizes the three years achievements of the three participating research groups; The Weizmann group, Tel-Aviv group and Purdue group. The firs part describes the achievements obtained by Shai's group toward the elucidation of the mechanism of membrane insertion and the structural organization of the pores formed by the Cry3A and Cry1Ac B. thuringiensis d-endotoxins. For that purpose Shai's group synthesized, fluorescently labeled and structurally and functionally characterized peptides corresponding to the seven helices that compose the pore-forming domain of Cry3A toxin, including mutants peptides and the hairpin a4G-a5 of both Cry3A and Cry 1Ac toxins composed of a4, a5 and the loop connecting a4-a5. Among the synthesized peptides were three mutated a4 helices based on site directed mutagenesis done at Aronson's group that decreased or increased Cry 1Ac toxicity. The results of these studies are consistent with a situation in which only helices a4 anda5 insert into the membrane as a helical hairpin in an antiparallel manner, while the other helices lie on the membrane surface like ribs of an umbrella (the "umbrella model"). In order to test this model Shai's group synthesized the helical hairpin a4<-->a5 of both Cry3A and Cry 1 Ac toxins, as well. Initial functional and structural studies showed direct correlation between the properties of the mutated helices and the mutated Cry1Ac. Based on Shai's findings that a4 is the second helix besides a5 that insert into the membrane, Aronson and colleagues performed extensive mutation on this helix in the CrylAc toxin, as well as in the loop connecting helices 4 and 5, and helix 3 (part two of the report). In addition, Aronson performed studies on the effect of mutations or type of insect which influence the oligomerization either the Cry 1Ab or Cry 1Ac toxins with vesicles prepared from BBMV. In the third part of the report Zilberstein's and Sneh's groups describe their studies on the three domains of Cry 1C, Cry 1E and crylAc and their interaction with the epithelial membrane of the larval midgut. In these studies they cloned all three domains and combinations of two domains, as well as cloning of the pore forming domain alone and studying its interaction with BBMV. In addition they investigated binding of Cry1E toxin and Cry1E domains to BBMV prepared from resistant (R) or sensitive larvae. Finally they initiated expression of the loop a4G<-->a5 Cry3A in E. coli to be compared with the synthetic one done by Shai's group as a basis to develop a system to express all possible pairs for structural and functional studies by Shai's group (together with Y. Shai).

Abstract:
More than 60% of plant viruses are positive-strand RNA viruses that cause billion-dollar losses annually and pose a major threat to stable agricultural production, including cucumber mosaic virus (CMV) that infects numerous vegetables and ornamental trees. A highly conserved feature among these viruses is that they form viral replication complexes (VRCs) to multiply their genomes by hijacking host proteins and remodeling host intracellular membranes. As a conserved and indispensable process, VRC assembly also represents an excellent target for the development of antiviral strategies that can be used to control a wide-range of viruses. Using CMV and a model virus, brome mosaic virus (BMV), and relying on genomic tools and tailor-made large-scale resources specific for the project, our original objectives were to: 1) Identify host proteins that are required for viral replication complex assembly. 2) Dissect host requirements that determine viral host range. 3) Provide proof-of-concept evidence of a viral control strategy by blocking the viral replication complex-localized phospholipid synthesis. We expect to provide new ways and new concepts to control multiple viruses by targeting a conserved feature among positive-strand RNA viruses based on our results. Our work is going according to the expected timeline and we are progressing well on all aims. For Objective 1, among ~6,000 yeast genes, we have identified 96 hits that were possibly play critical roles in viral replication. These hits are involved in cellular pathways of 1) Phospholipid synthesis; 2) Membrane-shaping; 3) Sterol synthesis and transport; 4) Protein transport; 5) Protein modification, among many others. We are pursuing several genes involved in lipid metabolism and transport because cellular membranes are primarily composed of lipids and lipid compositional changes affect VRC formation and functions. For Objective 2, we have found that CPR5 proteins from monocotyledon plants promoted BMV replication while those from dicotyledon plants inhibited it, providing direct evidence that CPR5 protein determines the host range of BMV. We are currently examining the mechanisms by which dicot CPR5 genes inhibit BMV replication and expressing the dicot CPR5 genes in monocot plants to control BMV infection. For Objective 3, we have demonstrated that substitutions in a host gene involved in lipid synthesis, CHO2, prevented the VRC formation by directing BMV replication protein 1a (BMV 1a), which remodels the nuclear membrane to form VRCs, away from the nuclear membrane, and thus, no VRCs were formed. This has been reported in Journal of Biological Chemistry. Based on the results from Objective 3, we have extended our plan to demonstrate that an amphipathic alpha-helix in BMV 1a is necessary and sufficient to target BMV 1a to the nuclear membrane. We further found that the counterparts of the BMV 1a helix from a group of viruses in the alphavirus-like superfamily, such as CMV, hepatitis E virus, and Rubella virus, are sufficient to target VRCs to the designated membranes, revealing a conserved feature among the superfamily. A joint manuscript describing these exciting results and authored by the two labs will be submitted shortly. We have also successfully set up systems in tomato plants: 1) to efficiently knock down gene expression via virus-induced gene silencing so we could test effects of lacking a host gene(s) on CMV replication; 2) to overexpress any gene transiently from a mild virus (potato virus X) so we could test effects of the overexpressed gene(s) on CMV replication. In summary, we have made promising progress in all three Objectives. We have identified multiple new host proteins that are involved in VRC formation and may serve as good targets to develop antiviral strategies; have confirmed that CPR5 from dicot plants inhibited viral infection and are generating BMV-resistance rice and wheat crops by overexpressing dicot CPR5 genes; have demonstrated to block viral replication by preventing viral replication protein from targeting to the designated organelle membranes for the VRC formation and this concept can be further employed for virus control. We are grateful to BARD funding and are excited to carry on this project in collaboration.
