PhD position Structural elucidation of membrane-remodeling protein complexes by cryo-EM

A fully funded 4-year position is available in the laboratory Structure and Function of Membrane Proteins at the VIB-VUB Center for Structural Biology, Brussels, The project focuses on the structural elucidation of membrane-remodeling protein complexes from the endoplasmic reticulum and integrates fundamental cell biology and structural biology by cryo-electron

The asymmetrical distribution of lipids in biological membranes is a well-established biological paradigm and essential for signaling and organelle-/protein While the regulated asymmetry in the plasma membrane of eukaryotic cells is well-studied, much less is known about the symmetry or asymmetry of lipid bilayers in intracellular The endoplasmic reticulum plays a central role in this context as lipids are retrieved from its cytosolic leaflet for export to acceptor Interleaflet balance and availability of lipid species in the leaflets of the endoplasmic reticulum membrane are governed by scramblases, a functional lipid transporter class (Brunner et , Nature, 2014) that only recently was recognized to be required for non-vesicular lipid transport and as essential host factor(s) for virus

We aim to structurally characterize scramblases involved in lipid export from the endoplasmic reticulum and reveal their roles, organization, and interactome in the In addition, the mechanisms of viral hijacking of scramblase host factors for the assembly and spread of viruses are a matter of

We apply state-of-the-art methods for the expression and purification of delicate membrane protein complexes in cultured mammalian cells and their subsequent biophysical and biochemical characterization by HPLC, SEC-MALS, and functional reconstitution into Proteins will be further characterized in living cells by confocal microscopy located in the For structural work, single particle cryo-electron microscopy is extensively utilized at Belgium s prime location, the Biological Electron Cryogenic Microscopy Center of Flanders (BECM) on the VUB
