The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport.

Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, this project aims to uncover the link between the unique geometry of HIV capsids and their ability to subvert the nucleus’ defenses. The expected outcome is a step-change in the understanding of nuclear access control, with downstream benefits to virology, bio-engineering and bio-technology.Read moreRead less
Improving the stability of biomolecules using ionic liquids. This project aims to address critical issues in studying proteins outside their native environments by developing new solvents that will increase their stability and solubility. The project expects to create new knowledge in our understanding of solvent chemical properties through a novel approach using high throughput robotics, synchrotron analysis of protein structures and Molecular Dynamics simulations. The expected outcome is a set ....Improving the stability of biomolecules using ionic liquids. This project aims to address critical issues in studying proteins outside their native environments by developing new solvents that will increase their stability and solubility. The project expects to create new knowledge in our understanding of solvent chemical properties through a novel approach using high throughput robotics, synchrotron analysis of protein structures and Molecular Dynamics simulations. The expected outcome is a set of design rules for creating new solvents. This should benefit many research and industrial applications, including determining protein structure for the development of new drugs and biocatalysts, and cryopreservation of protein-based pharmaceuticals.Read moreRead less
