We investigate the mechanisms of dynamic compartmentalization of the protein synthesis machinery in mammals, molecular composition and cancer-related features of the translation elongation factor 1 (eEF1) complex, spatial structure, expression, post-translational modifications and functions of the normal and proto-oncogenic isoforms of translation elongation factor 1A (eEF1A)
Current research activities:
- The concept of vectorial transfer of tRNA during translation elongation process in mammalian cells has been established. Molecular mechanisms of tRNA channeling have been uncovered
- Spatial structures of A1 and proto-oncogenic A2 isoforms of mammalian eEF1 have been shown to be different despite 97 % homology of their amino acid sequences. Differential interaction of the isoforms with protein partners has been demonstrated which might be important for oncogenecity of A2
- X-ray structure of the proto-oncogenic A2 isoform has been obtained, in collaboration with Department of Protein Synthesis Enzymology, and some peculiariries in the mechanism of GTP/GDP exchange have been reveiled
- Mechanism of overexpression of A2 in tumors has been shown to be related to special microRNAs whose role has been predicted theoretically and proved experimentally
- The components of macromolecular eEF1 complex have been shown to function independently from the complex in human cancer cells and tissues where the subunits may apparently fulfill a non-translational role
