Iron 20-24 frataxin Homo sapiens 0-8 26286937-3 2015 Frataxin chaperones iron in the mitochondrial matrix and regulates the iron-sulfur cluster (ISC) assembly complex. Iron 71-75 frataxin Homo sapiens 0-8 26286937-5 2015 Decreased expression of frataxin is associated with decreased ISC assembly, mitochondrial iron accumulation, and increased oxidative stress, all of which contribute to mitochondrial dysfunction. Iron 90-94 frataxin Homo sapiens 24-32
