Our conferences bring together researchers interested in membrane structure and function from various disciplines, including biochemistry, biophysics, spectroscopy, chemical biology, polymer chemistry, advanced imaging, and cell biology.

The development of innovative extraction methods, such as copolymers like SMA, membrane protein scaffolds, saposins, peptidiscs, and native vesicle extractionhas driven progress in this field.

Amphipathic polymers fragment membranes into water-soluble discs, allowing the complex structures and interactions found in vivo to be discerned, without requiring synthetic detergents or artificial lipids. This is yielding new insights, tools and models of how membranes operate and can be manipulated.

Join us to find out about the latest structures of native membrane proteins, how to capture memteins with polymers, and new tools and applications of nanodiscs.

Thomas Walz, Rockefeller University, applies cryo-electron microscopy to resolve macromolecular complexes and membrane proteins involved in vesicular transport, cell adhesion, olfaction and insulin signaling, and will present Cryo-EM studies of Membrane Proteins in Peptidiscs & Nanodiscs. (Cancelled on March 19 due to pressing COVID-19 related duties). PDF slides.

Youzhong Guo, Professor, Department of Medicinal Chemistry, Virginia Commonwealth University, is focussed on the structural biology will give a talk on SMA-based Membrane Active Polymers for Membrane Protein Structural Biology. PDF slides

Jie Yu will speak on the Mechanism of gating and partial agonist action in the glycine receptor.
