Kalydeco’s Efficacy Tied to Phosphorylation Levels of CFTR Protein, Study Suggests
CFTR channel activity is controlled by a molecular process known as phosphorylation. Now, a study suggests that the levels of phosphorylation affect how well Kalydeco works in people with certain mutations in the CFTR gene. The study “VX-770-mediated potentiation of numerous human CFTR disease mutants is influenced by phosphorylation level” was…
