Pucadyil Lab
Membrane remodelling in cellular physiology
The ~5 nanometer-thin biological membrane is formed spontaneously by the the non-covalent assembly of amphipathic lipids. Membranes are fluid and capable of resealing quickly upon rupture thereby making them highly resilient materials. Perhaps, this feature explains why lipids were selected over the course of evolution to form membranes that encapsulate all living entities. Membranes are also elastic materials that resist remodelling. But biological membranes are constantly bent out of shape, cut and resealed through budding, fission and fusion reactions, which are collectively referred to as membrane remodelling.
​
Membrane remodelling is managed by specialised protein machines. The Pucadyil Lab focuses on discovering membrane remodelling proteins and understanding their mechanistic and regulatory aspects. We carry out biochemical screens to identify such proteins, employ reconstitution approaches to understand how they work and investigate their functions in living systems.​
