About
Formation of plasma membrane is considered as a crucial event during evolution and life, as known today, would not be possible without them. Actual plasma membranes contain a complex, heterogeneous distribution of lipids and membrane proteins which interact to create important biological functions. To investigate this complex membrane environment significant progress has been made to model native membranes.
Our research group focuses on development of nature inspired models, in particular, surface tethered phospholipid membranes (tBLM) and membrane-protein complexes exhibiting catalytic activities. The group addresses problems related to basic life-science as well as applications in biomedicine. In particular, including sensor development for various endogenous and exogenous pathogens and ultrasensitive detection of microbial toxins (α-hemolysin (αHL), Vaginolysin (VLY), Pneumolysin (PLY), etc.).
We offer a broad spectrum of technological solutions to reconstitute proteins into the tethered bilayer for structural and functional studies. Bioelectrochemical and Biospectroscopic techniques and relevant expertise can be accessed by the external users through the standard open access procedures implemented at Vilnius University. We seek both academic and industrial partnerships to further develop molecular devices based on tethered bilayer technologies and advance basic knowledge in the field of the protein function in biological membranes. In particular, we seek to establish partnerships with theoretical groups having expertise in modelling structures of biomolecules in membranes as well as predicting the dynamic properties of ion carriers in confined nano-compartments. Also, we aim to spread our technological knowledge into the areas of biochemistry and molecular biology where the phospholipid milieu is required for functional reconstitution of membrane proteins for structural and functional studies. Joint initiatives for EU and other international funding for research and technology development are also sought-after.
Our resources contain proprietary technology and compounds for the production of the self-assembled molecular anchors and tethered phospholipid bilayers. Wide spectrum of electrochemical and spectroscopy instrumentation for molecular level characterization of the structure and function of phospholipid bilayers, membrane-protein interaction, detection of membrane-damaging toxins and surface visualization by the fluorescence and atomic force microscopies. Proprietary algorithms and software for the analysis of the electrochemical impedance response of tethered bilayers.
