Yeast frataxin mutants display decreased superoxide dismutase activity crucial to promote protein oxidative damage Irazusta, Verónica Patricia; Obis Monné, Èlia; Moreno Cermeño, Armando J.; Cabiscol Català, Elisa; Ros Salvador, Joaquim; Tamarit Sumalla, Jordi (Elsevier, 2010)Iron overload is involved in several pathological conditions, including Friedreich ataxia, a disease caused by decreased expression of the mitochondrial protein frataxin. In a previous study, we identified 14 proteins ...
Major targets of iron-induced protein oxidative damage in frataxin-deficient yeasts are magnesium-binding proteins Irazusta, Verónica Patricia; Moreno Cermeño, Armando J.; Cabiscol Català, Elisa; Ros Salvador, Joaquim; Tamarit Sumalla, Jordi (Elsevier, 2008)Iron accumulation has been associated with several pathological conditions such as Friedreich ataxia. This human disorder is caused by decreased expression of frataxin. Iron-overload triggers oxidative stress, but the ...
Frataxin depletion in yeast triggers up-regulation of iron transport systems before affecting iron-sulfur enzyme activities Moreno Cermeño, Armando J.; Obis Monné, Èlia; Bellí i Martínez, Gemma; Cabiscol Català, Elisa; Ros Salvador, Joaquim; Tamarit Sumalla, Jordi (The American Society for Biochemistry and Molecular Biology, 2010)The primary function of frataxin, a mitochondrial protein involved in iron homeostasis, remains controversial. Using a yeast model of conditional expression of the frataxin homologue YFH1, we analyzed the primary effects ...
