Zusammenfassung der Projektergebnisse
In this project, we used a cross-kingdom comparative approach to study the activities of multifunctional MIF proteins in members of different kingdoms of life (mammals, plants, aphids, fungi and protists). In humans, MIF (macrophage migration inhibitory factor) is a key signaling molecule implicated in immunity, and, therefore, its function decisively determines the outcome of infectious and inflammatory diseases and other adverse conditions. In a comprehensive in silico analysis, we first explored the diversity and deduced the evolutionary history of MIF proteins across organisms from all kingdoms of life. Our experimental approaches revealed that, unexpectedly, plant MIF proteins (MDLs) can bind to human MIF receptors and trigger signaling events in human cells. Yet unpublished work also successfully elucidated the structures of all three MDLs of the model plant Arabidopsis thaliana and identified an oligomerization-based mechanism of human/plant MIF synergism. We further showed that MDL functions in plants are related to controlling flowering time and modulating antibacterial immunity. We finally explored the potential of MIF genes as targets for insect control. In sum, our work expanded significantly the knowledge about a highly conserved eukaryotic protein family, which apart from mammals have not been studied extensively in other organismal taxa.
