Cystic fibrosis is caused by the absence of, or faults in, the CF transmembrane conductance regulator (CFTR) protein (shortened here to the ‘CF protein’). James Charlick, based at the University of Bristol, will use his Early Career Researcher Development Award to explore the implications of new insights into how the CF protein works at a microscopic level. Understanding tiny details about faults in this protein can help researchers design more effective medicines for CF and make them available to a wider group of people.
