Bitopic proteins having only one helical transmembrane (TM) domain are a class of biologically significant membrane proteins, including the type I receptors, which are involved in the regulation of different cellular processes in human organism. Either destroying or enhancing of their biological activity can result in many human diseases. Recent studies have been making it increasingly clear that specific helix-helix interactions of single-span TM domains are critical for lateral dimerization and modulation of biological function of bitopic proteins. Establishing structure-function relationship requires precise structural information about this class of objects. A combination of high-resolution NMR spectroscopy with optical spectroscopy, protein engineering and molecular modeling made it possible studies of the nature and the mechanisms of important TM helix-helix recognition and interactions inside the supramolecular complexes (detergent micelles and lipid bicelles) mimicking membrane environment. Using a robust strategy, we investigated recombinant TM fragments of a number bitopic proteins from different families of receptor tyrosine kinases, apoptotic proteins, as well as amyloid precursor protein APP, which play important roles in normal and in pathological conditions (e.g. oncogenesis and Alzheimer disease) of human organism by providing cell signaling, maintaining cellular homeostasis and controlling cell fate. We established spatial structure and internal dynamics of the monomeric and dimeric TM domains, characterized diverse TM helix-helix packing interfaces and obtained detailed atomistic picture of intra- and intermolecular interactions. Obtained information about structural-dynamic properties of the TM domains of studied bitopic proteins along with the available biophysical and biochemical data provides useful insights into the bitopic protein functioning at the atomic level.

Till Bärnighausen, Heidelberg University, GermanyHost: Halldór StefánssonSeminar Room 48e, EMBL Hamburg
Abstract: Infectious disease epidemics are cutting into life expectancies and inhibt human development in many countries worldwide. Interventions to prevent and treat infectious diseases can thus lead to major improvements in population health, social and economic outcomes. I will present modern infectious disease interventions research including all stages of the research process, with examples from large-scale population and health systems intervention studies in African and Asia, including novel programs to fight HIV, reduce sexually transmitted infections and to expand vaccination coverage. I will show empirical evidence for substantial improvements in popualtion health, educational attainment, labor market productivity and social functioning.
