Analysis of protein families structure

Supervisor: doc. RNDr. Radka Svobodová, Ph.D.

V současné době máme k dispozici nadkritické množství informací ohledně proteinových strukturních rodin. Konkrétně, pro většinu rodin známe stovky struktur jejích zástupců, přičemž tyto struktury pocházejí z různých organismů, některé z nich váží rozličné ligandy a mnohé obsahují různorodé mutace. Tyto informace umožňují analýzu „anatomie“ daných proteinových rodin. Například studium elementů sekundární struktury (šroubovic a skládaných listů), jejich vzájemného uspořádání, konzervovanosti a určování, které z těchto elementů jsou pro danou proteinovou rodinu klíčové a které se vyskytují jen raritně. Dále pak zkoumání proteinových tunelů a pórů, jejich charakteristik a četnosti jejich výskytu u jednotlivých zástupců proteinové rodiny. V rámci laboratoře LCC jsou vyvíjeny softwarové nástroje pro realizaci výše uvedených analýz, např. software MOLE, LiteMol, SecStrAnalyzer. Hlavním cílem disertační práce je zaměřit se na několik konkrétních biologicky významných proteinových rodin (např. cytochromy, poriny, dehalogenázy, proapoptotické proteiny) a provést jejich detailní analýzu. Dalším cílem je spolupráce při vývoji uvedených softwarových nástrojů.

Mechanism of action of antimicrobial peptides

Supervisor: doc. RNDr. Robert Vácha, PhD.

OBJECTIVES: The aim is to elucidate the relationship between molecular properties of amphiphilic peptides and their ability to translocate and form transmembrane pores in membranes with various lipid compositions. The obtained understanding will be used for the development of new antimicrobial peptides, which can serve as a new type of antibiotic drugs.

DESCRIPTION: Antibiotic-resistant bacteria cause more than 700 000 deaths per year, and the forecast is 10 million per year in 2050. Moreover, emerging strains of bacteria resistant to all available antibiotics may lead to a global post-antibiotic era. Because of this threat, the WHO and the UN are encouraging the research and development of new treatments. Antimicrobial peptides are promising candidates for such new treatments. We will study the molecular mechanism of action of antimicrobial peptides and determine the critical peptide properties required for membrane disruption via the formation of transmembrane pores and spontaneous peptide translocation across membranes. Based on the obtained insight, we will design new peptides and test their abilities. The most effective peptides will be evaluated for antimicrobial activity and human cell toxicity using growth inhibition and hemolytic assays, respectively. Student(s) will master tools of computer simulations, in particular, molecular dynamics techniques and methods to calculate free energies. Moreover, he/she will learn the advantages and disadvantages of various protein and membrane parameterizations, including all-atom and coarse-grained models. The simulations will be complemented by in vitro experiments using fluorescent techniques.

EXAMPLES of potential projects: * Antimicrobial peptides and formation of membrane pores * Synergistic mechanisms between antimicrobial peptides * Membrane disruption by antimicrobial peptides in non-equilibrium conditions

Protein Affinity and Selectivity to Cellular Membranes

Supervisor: doc. RNDr. Robert Vácha, PhD.

OBJECTIVES: The aim is to elucidate the relationship between protein sequence and preferred composition and curvature of human membranes,i.e., find peptide motifs that are selective to specific membranes in cells (plasma membrane, endoplasmic reticulum, Golgi apparatus, mitochondria, etc.). The obtained understanding will be used for the development of new protein biomarkers, sensors, scaffolds, and drugs.

DESCRIPTION: The control of biological membrane shape and composition is vital to eukaryotic life. Despite a continuous exchange of material, organelles maintain a precise combination and organization of membrane lipids, which is crucial for their function and the recruitment of many peripheral proteins. Membrane shape thus enables the cell to organize proteins and their functions in space and time, without which serious diseases can occur. Moreover, membrane curvature and lipid content can be specific to cancer cells, bacteria, and enveloped virus coatings, which could be utilized for selective targeting. We will develop a new method, using which we will elucidate the relationship between the protein sequence and the preferred membrane. The relationship will lay the foundations for the design of new protein motifs sensitive to membranes with a specific curvature and composition. Student(s) will master tools of computer simulations, in particular, molecular dynamics techniques and methods to calculate free energies. Moreover, he/she will learn the advantages and disadvantages of various protein and membrane parameterizations, including all-atom and coarse-grained models.

EXAMPLES of potential projects: * Determination of helical motifs for specific membrane compositions * Development of implicit membrane model for fast determination of protein-membrane affinity * Helical peptides and their sensitivity for membrane curvature

Protein Structure and Dynamics

Supervisor: prof. Mgr. Lukáš Žídek, Ph.D.

The research goal is investigation of structure, dynamics, and biologically relevant properties of proteins, using NMR spectroscopy and other high-resolution approaches. Currently, our group is mostly interested in studies of molecular motions using NMR relaxation and relaxation dispersion; in studies of protein disorder using NMR approaches providing sufficient resolution (usually based on non-uniformly sampled high-dimensional spectra); and in studies of interactions of intrinsically disordered proteins with their binding partners (using NMR, cryo-EM, and biophysical methods). The systems currently studied in the laboratory include bacterial RNA polymerases and microtubule associated proteins.

We are inetrested structure and dynamics of well-ordered and domains of subunits and sigma factors of RNA polymerase from B. subtilis, characterization of structural features and dynamics of disordered domain, and in importance of electrostatic interactions for structural properties and biological function of the protein. Currently we extend our interest to mycobacterial RNA polymerase.

Microtubule associated protein 2c (MAP2c) is a key factor regulating microtubule dynamics in developing brain neurons, and an example of an intrinsically disordered proteins with an important physiological function and detectable structure-function relationship. The first goal is to study MAP2c in a natural complexity and by methods providing atomic resolution. Such methods include paramagnetic relaxation interference, to detect and describe transient local structures of MAP2c important for its function, and real-time NMR, to monitor kinetics of MAP2c phosphorylation by relevant kinases of different signalling pathways. The second goal is to characterize interactions of MAP2c with biologically important binding partners, especially with isoforms and a monomeric form of regulatory protein 14-3-3. The third goal is to test the effect of cellular environment on MAP2c by recording NMR spectra at near-to-native conditions (in cells and/or cell lysates) and/or by performing cryo-electron tomography on monolayered neurons.

  • Interactions underlying physiological function of Microtubule Associated Protein 2c
  • Structure, dynamics and interactions of bacterial RNA polymerase subunits and sigma factors
Proteins structure alteration and their involvement in complex formation relevant for neurodegenerative disease.

Supervisor: RNDr. Mgr. Jozef Hritz, Ph.D.

BACKGROUND: Several neurodegenerative diseases are associated with the formation of fibrous protein aggregates. The fibrillization of amyloid beta peptide into amyloid plaques and the agregation of hyperphosphorylated tau protein into neurofibrillar tangles are main neuropatological signs of Alzheimer disease. Studying of how different factors influence the formation of biomolecular complexes is the key for understanding underlying molecular mechanism of neurodegerative processes. The described activities are part of international research projects allowing to spend the part of PhD study at the collaborative groups in Europe or North and South America and to learn specific research techniques, there.

OBJECTIVES: The research aims to elucidate molecular mechanisms of conformational changes leading to the modified potential of biomolecular complex formation. Interdisciplinary approach combining computational biophysical chemistry, structural biology, bioinformatics and biophysical interaction techniques will be applied.

FOCUS: Doctoral research projects focus on the monitoring of post-translational modification of studied proteins, their interaction with adaptor proteins and induced conformational changes. Students benefit from outstanding research facilities of CEITEC-MU that include cryoEM tomography, NMR, AFM, and biophysical interaction methods.

EXAMPLES of potential student doctoral projects:

  • Are Tau fibrils induced by phosphorylation and the interaction with 14-3-3 proteins relevant for Alzheimer disease?
  • A Tau conformational changes induced by phosphorylation and 14-3-3 proteins relevant in neurodegenerative diseases
  • Oligomerization states within the 14-3-3 protein family
  • Computational prediction of biomolecular complexes and their statibities

RNA Quality Control

Supervisor: doc. Mgr. Štěpánka Vaňáčová, Ph.D.

The internal and external RNA modifications play crucial roles in a number of essential processes of eukaryotic organisms. They regulate the production of germ cells, cellular differentiation, response to stress, and defects in this pathway have been linked to a number of human diseases.

The aim of PhD projects is to study in details on how specific terminal RNA modifications regulate cellular differentiation and to study the protein-protein interactions of factors involved in the regulation of adenosine methylation (m6A) in coding and noncoding RNAs.

Prospective student should ideally have done masters in molecular biology/biochemistry and have laboratory experience in nucleic acids and/or protein purification and analysis. The most highly valued feature will, however, be excitement for science and a strong drive in tackling important biological questions.


  • The role of posttranscriptional RNA modifications in cell differentiation
  • The role of protein-protein interactions in the dynamics of m6A RNA modification

Structural biology of WNT signalling

Supervisor: Konstantinos Tripsianes, Ph.D.

We apply structural biology methods in order to gain a mechanistic view of CK1ε action in the Wnt signalling pathways. CK1ε represents an attractive therapeutic target but currently two key steps in the CK1ε-mediated Wnt signal transduction are unclear: how CK1ε gets activated and/or engages target proteins in response to Wnt signal and how CK1ε phosphorylates its key substrate Dishevelled (DVL).

Our preliminary data suggest that we can efficiently apply methods of integrated structural biology to (i) probe the DVL conformational landscape using in vitro and in vivo FRET sensors coupled to SAXS and CryoEM, (ii) understand the (auto)phosphorylation regulatory mechanisms of CK1ε, (iii) analyse by NMR the functional consequences of DVL phosphorylation and (iv) monitor DVL phosphorylation by real-time NMR under controlled cellular conditions. The position is part of a multidisciplinary project that combines (i) cellular and molecular biology, (ii) proteomic analysis, (iii) biochemistry and structural biology, and received generous funding in a very competitive grant scheme.

Keywords: CK1ε, WNT, DVL phosphorylation, SAXS, cryo-EM, cryo-electron microscopy, real-time NMR
