Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes.

Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less

The twenty first century is said to be the century of biology. And there is no doubt that the development of our understanding of biological system is continuing at a massive rate. However as our understanding deepens, we need to draw on the whole range of scientific disciplines to proceed. This Centre draws together a multidisciplinary team of world-leading scientists to address one the key questions in modern biology, the structure of a membrane protein. We will develop techniques based on the latest developments in theoretical physics & chemistry, imaging, biology and technology - including the new Australian Synchrotron - to create new approaches to structural biology.Read moreRead less
