Professional interests/research projects:

Ekaterina Lukmanova's laboratory investigates human three-loop proteins of the Ly6/uPAR family and related neurotoxins from snake venom. The focus is on the molecular mechanisms of interaction of the studied proteins with their receptors. The laboratory team owns advanced technologies for the recombinant production of "three-loop" proteins that are not available from natural sources. This allowed for the first time to study the spatial structure and conduct a number of functional studies of such human proteins as Lynx1 and Lypd6 (neuroplasticity regulation factors), as well as SLURP-1 and SLURP-2 (auto/paracrine regulators of epithelial cells). Based on these proteins, the development of prototype drugs that improve cognitive function, anti-cancer drugs, as well as drugs aimed at the treatment of a number of skin diseases is currently being developed.
Laboratory research is carried out using the methods of protein engineering, cell biology, neurophysiology, electrophysiology and structural biology. In the field of NMR spectroscopy, the laboratory cooperates with the Laboratory of Structural Biology of Ion Channels of the Institute of Bioorganic Chemistry, Russian Academy of Sciences, in the study of voltage-gated human ion channels. Recently, the laboratory has been actively developing structural studies of ion channels using cryo-electron microscopy. The combined use of NMR spectroscopy, cryoelectron microscopy, and computer simulation made it possible for the first time to reveal an unusual type of interaction between a three-loop neurotoxin and the nicotinic acetylcholine receptor.
