Most of the studies prompt the suggestion that the iron and sulfur atoms required for the ISC biogenesis on Isu1/Isu2 are donated by other proteins, named Frataxin and Nfs1 [20]. This ISC biogenesis machinery is not yet well understood and problems in it cause several human diseases linked to protein/enzyme deficits.

The Herrenhausen Symposium on Neurodegeneration

Nature Medicine 16, 1200 (2010), Published online: 4 November 2010 | doi:10.1038/nm1110-1200

Although the pathological hallmarks of neurodegenerative diseases have been described for over 100 years, our understanding of the molecular events leading to neuronal death has emerged over the past two decades. Despite all of this progress in basic research, why do we still lack disease-modifying therapeutics?
