Research Overview

Cellular function is underpinned by the capacity to control the passage of molecules across membranes, and discrete macromolecular machineries have evolved for the transport of ions, metabolites and newly synthesised proteins.

Our chief interests lie in the mechanisms, regulation and interplay of systems facilitating membrane transport and cellular signalling, and the lab specifically focuses on two modes of molecular transport: protein translocation and ion conduction. To elucidate the mechanistic principles underpinning these systems we use X-ray crystallography as a central methodology for identification of systematic conformational changes of functional relevance.

Other projects in which we are involved include the leucine-rich repeat-containing G protein coupled receptors (in collaboration with the Visvader lab), and calcium signalling.
