Membrane remodelling in cellular physiology

Cell membranes are formed by the spontaneous self-assembly of amphipathic lipids into a 5 nanometer-thin bilayer sheet. Membranes are fluid and capable resealing quickly upon rupture. Membranes are also elastic and resist budding, fission and fusion. Perhaps, these qualities lie at the heart of why nature chose lipids to contain every know life form. 

But cells are filled with numerous membrane-bound compartments, which implies that cells have evolved mechanisms to remodel membranes. Remodelling requires specialised protein machines that bend membranes for budding, fission and fusion. Together, these function to manage vesicular transport of lipids and proteins, organelle growth and division, and wound healing and naturally have a tremendous impact on cellular physiology. 

The Pucadyil Lab focuses on understanding the mechanistic and regulatory aspects of membrane budding, fission and fusion reactions. We employ biochemical reconstitution approaches on model membrane templates and combine molecular modeling and cell biology to understand how membrane remodelling protein machines work.
