PROTEIN FOLDING AND DISEASE THE MITOCHONDRIAL PROTEIN FRATAXIN

This dissertation focuses on the study of frataxin, a small mitochondrial protein whose deficiency is associated with the neurodegenerative disease Friedreich's ataxia (FRDA). Aiming at a better understanding of frataxin conformational and functional properties, two lines of research were followed: first, the effect of FRDA-related mutations in human frataxin (FXN) were studied and the role of oxidative stress related modification addressed; second, yeast frataxin (Yfh1) orthologue was used to explore the conformational and functional properties of the protein.(...)
