Polarized vesicular trafficking is essential for many vital processes in all eukaryotic cells. Membrane vesicles transporting cellular material are targeted to distinct endomembrane domains characterized by their specific lipid-protein composition. Principal cell polarity regulators in eukaryotes mediating the vesicle trafficking are the exocyst complex and the clathrin coat. In the first part of my talk, I will present our data on the molecular architecture of the plant exocyst complex and its recruitment to the plasma membrane. Our multidisciplinary approach has uncovered novel plant-specific features of the exocyst complex and emphasized the importance of the specific protein-lipid code to recruit peripheral membrane proteins. In the second part, I will focus on crosstalk between exocytosis and clathrin-mediated trafficking. I successfully purified and biochemically characterized clathrin-coated vesicles from plant cells. This represents the first step to get molecular insight into the mechanisms bridging the clathrin-coated vesicles and the exocyst complex.
The talk will be held on 20th April starts at 15:00.
