The laboratory was established in 2005 on the basis of a Group with the same name for studying protein folding processes, establishing the factors determining the occurrence of amorphous aggregates and amyloid fibrils, studying the structure, stability and dynamics of globular proteins in native and denatured partially-folded states, studying disordered proteins and their complexes. Currently, the study is aimed at solving modern problems of functional cell proteomics, including the role of macromolecular crowding in the organization of supramolecular protein-protein and nucleoprotein complexes and non-membrane cell organelles.

CURRENT RESEARCH TOPICS
  • Investigation of the macromolecular crowding effect on the kinetic processes of proteins folding-unfolding, the formation by target proteins, including intrinsically disordered proteins, of macromolecular and supramolecular protein complexes with each other and other macromolecules. The study of proteins phase separation and the study of the role of crowding in the formation of supramolecular protein complexes, transport channels of biologically important substances and non-membrane organelles of the cell.
     
  • Investigation of the physico-chemical properties of biomarkers of a new generation on the basis of bacterial phytochromes in complex with biliverdin, whose spectral properties correspond to the so-called "biological window of transparency".
     
  • Study of the kinetics of formation and polymorphism of amyloid fibrils, as well as factors affecting their growth rate and structure. Investigation of the photophysical properties of benzothiazole dye thioflavin T, used to diagnose the formation and study of the structure of amyloid fibrils. Creation and investigation of new improved fluorescent probes for the study of amyloid fibrils in vitro and in vivo.

MAIN SCIENTIFIC RESULTS AND ACHIEVEMENTS

Obtained results to the development of the intrinsic UV-fluorescence method: it was shown that analysis of the properties of the microenvironment of individual tryptophan residues allows predicting the fluorescent properties of proteins, recording of the fluorescence polarization can be used as a tool for studying of their dynamic structure. The work was supported by the Russian Foundation for Basic Research. (Publications).

On the actin example, the role of intracellular folding machinery in the formation of the native state of proteins was demonstrated. It was found that the so-called inactivated actin, long considered an intermediate state of the protein, is in fact a thermodynamically stable monodisperse associate, whose molecular mass is 14-16 times larger than the mass of the actin macromolecule. The structure of inactivated actin is determined by the amino acid sequence of the protein, while native G-actin, capable to polymerize, is a quasi-stationary, kinetically stable structure resulting from ATP-dependent processes involving chaperones and chaperonins. The work was supported by the Russian Foundation for Basic Research and grants from Program 'Molecular and Cell Biology' of the Presidium of the RAS. (Publications).

Amyloid fibrils on the basis of different amyloidogenic proteins were studied using various spectroscopic approaches and the EM method, as well as by studying their interaction with specific fluorescent probes. The spectral and photophysical properties of the benzothiazole dye thioflavin T - a widely used probe for diagnostics of the fibrils formation, were first explained on the basis of the molecular rotor nature of the dye molecule. An experimental confirmation of the existence of thioflavin T excimers in aqueous solutions at a high dye concentration was obtained and a monomeric model of its incorporation into amyloid fibrils was proved. The derivatives and analogues of thioflavin T with improved photophysical properties, which have prospects for use in the study of amyloid fibrils in vivo were synthesized and studied. It is shown that the fluorescent approach, widely used to determine the binding parameters of thioflavin T with amyloid fibrils, has a number of limitations and is often used incorrectly. To solve this problem, two methodical developments were made, one of which is based on the preparation of the dye solutions with fibrils by equilibrium microdialysis, and the other on the correction of the recorded fluorescence intensity of the dye bound to fibrils on the inner filter effect. Determination of the binding parameters of thioflavin T with amyloid fibrils on the basis of various amyloidogenic proteins showed that the application of the developed approach opens new possibilities for using this dye, its analogs and derivatives to study the kinetics of formation and polymorphism of amyloid fibrils. This work was supported by the Russian Foundation for Basic Research, grants from the Program 'Molecular and Cell Biology' of the Presidium of the RAS, scholarships from the President of the Russian Federation, grant from the Dynasty Foundation, and the state contract with the Ministry of Education and Science. (Publications).

A study of the physicochemical and spectral properties of GFP-like fluorescent proteins and fluorescent proteins developed on the basis of bacterial phytochromes made it possible to explain a number of properties of these proteins that are essential for their use as biomarkers. It was shown that the quaternary structure of fluorescent proteins is an important but not the only factor determining the differences in their resistance to the denaturing effect of guanidine hydrochloride and heating. The obtained results are essential for understanding the folding processes and factors that stabilize the structure of beta-barrel-type proteins. Data on the interaction of the green fluorescent protein sfGFP with various chemical denaturants (guanidine thiocyanate, guanidine hydrochloride) in pre-denaturational concentrations and salts (NaCl, sodium thiocyanate) were obtained. It was shown the presence of specific sites for negatively charged ions in the surrounding of sfGFP chromophore, the binding of SCN- and Cl- ions to which significantly changes the spectral characteristics of the protein. The spectral properties of dimeric fluorescent markers iRFP713, iRFP682 and iRFP670 and their mutant forms were studied. It is shown that the spectral properties of dimeric near infrared proteins (NIR FPs) are largely determined by the intermonomer and interdomain allosteric influence of cysteine residues, which prevents or facilitates the covalent binding of biliverdin in the second monomer of dimeric NIR FPs. A mutant form of iRFP713 / V256C has been created, which has the highest of all NIR FPs created to date fluorescence quantum yield and fluorescence brightness in vivo and in vitro. The work was supported by the Russian Foundation for Basic Research, scholarships from the President of the Russian Federation and grants from the Program 'Molecular and Cell Biology' of the Presidium of the RAS. (Publications).

The study of ligand-binding proteins (odorant-binding proteins, glutamine-binding protein (GlnBP), D-galactose / D-glucose binding protein (GGBP), and trehalose / maltose binding protein (TMBP)) was performed in connection with their possible use as a sensitive elements of biosensor systems. A comparative study of the structure, stability, and conformational changes in the folding-unfolding process of GGBP from E. coli, and TMBP from Thermococcus litoralis, having a similar topology, showed significantly higher stability of TMBP compared to GGBP, which makes it most promising for use as a sensitive element of fluorescent biosensors on glucose. The work was financially supported by grants from INTAS and NATO, state contracts with the Ministry of Education and Science, scholarships from the President of the Russian Federation and grants from the Program 'Molecular and Cell Biology' of the Presidium of the RAS. (Publications).

The influence of macromolecular crowding on the structure, stability, folding-unfolding processes, folding failure and aggregation of a large number of proteins that differ significantly in their physico-chemical properties was studied. It is shown that the experimental data can not be explained only within the concept of excluded volume, according to which crowding conditions stimulate structural changes and interactions of target proteins, leading to a decrease in the free volume. When interpreting the results, it is necessary to take into account the influence of crowding agents on the structure of the solvent, as well as the weak interactions between the target protein molecule and macromolecules - crowding agents. The most important feature of macromolecules is, apparently, their ability to separate into phases after reaching a certain critical concentration in the solution. The work was carried out with the financial support of the RSF Grant (project No. 14-24-00131). (Publications).
