Content of research

In collaboration with L. Krasný (Institute of Microbiology, Academy of Sciences of the Czech Republic, Prague, Czech Republic), we study subunits and sigma-factors unique for RNA polymerase of Gram-positive bacteria. We have determined structure of well-ordered N-terminal domain of delta subunit and characterized structural features of its intrinsically disordered C-terminal domain. In addition to the structural description, we characterized dynamics of both domains at various time scales using NMR relaxation. Investigation of other subunits and sigma-factors is in progress.

Multidisciplinary research of proteins involved in plant hormone signaling cascades is an example of a collaborative project within CEITEC (J. Hejtko, Functional Genomics and Proteomics of Plants). We have studied dynamics of receiver domain of the sensory kinase CKI1 and characterized its interactions with Mg(2+) ions and a phosphate analogue. We are involved in characterization of interactions of the CKI1 receiver domain with its down-stream partners and in structural studies of other sensory kinases (e.g. ETR1).

Traditionally, the strength of the group has been development of NMR methodology for atomic-resolution studies of proteins and nucleic acids. Recently, several fruitful collaborations witnessed that we are able to apply our know-how to solve real biological problems that were hard to attack by the conventional approaches. In the future, we would like to continue to develop in this direction and to complement the existing successful collaboration with our own projects. We plan to study dynamics, structural properties, function and regulation of Microtubule Associated Protein 2c (MAP2c), a cytoskeletal protein important for development of neuronal cells. The free form of the protein is disordered and relatively large (49 kDa), which makes it a challenging target for NMR. Our preliminary results show that the methodology developed in our group is sufficient for such a type of molecule.

1. Impact of 14-3-3 protein on the formation of protein aggregates involved in neurodegenerative diseases

Supervisor:  RNDr. Mgr. Jozef Hritz, Ph.D.
Consultant: doc. Mgr. Vítězslav Bryja, Ph.D., Mgr. Jan Přibyl, Ph.D.


The neuronal cells of patients suffering from neurodegenerative diseases are characteristic by possession of aggregates of several proteins such as tau and Abeta protein. They form toxic aggregates to the different extend depending on the environment and their state (e.g. different post-translational modifications or specific conformational state). The main aim of this PhD project will be to quantify the extent of aggregation of three selected proteins in vitro and in the cell environment. Dependence of aggregation on phosphorylation and the potential interaction with various forms of 14-3-3 proteins will be analyzed mostly by biophysical interaction techniques and the atomic force microscopy. The biological relevance of the in-vitro findings will be tested in cell cultures by fluorescence microscopy.

2. Structural changes of the selected protein fibrils induced by phosphorylation and the interaction with 14-3-3 proteins

Supervisor:  RNDr. Mgr. Jozef Hritz, Ph.D.
Consultant: doc. Mgr. Vítězslav Bryja, Ph.D., Dr. Tanvir Shaikh


Several neurodegenerative diseases are asociated with the formation of fibrous (fibrillar) protein agreggates. 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 protein fibrils is the key for understanding this neurodegerative processes. The main aim of this PhD project will be characterization of structural changes in the formation of protein fibrils due to different phosphorylation state and the interaction with 14-3-3 proteins. Interdisciplinary approach combining molecular biology and structural biology (mainly cryoEM tomography) methods will be applied. Molecular binding mode involving 14-3-3 will be elucidated by NMR.
