Mechanism of frataxin “bypass” in human iron-sulfur cluster biosynthesis with implications for Friedreich’s ataxia

Deepika Das, Shachin Patra, Jennifer Bridwell-Rabb, and David P. Barondeau; J. Biol. Chem. jbc.RA119.007716. doi:10.1074/jbc.RA119.007716

These results reveal an unexpected mechanism that replaces FXN-based stimulation of the Fe-S cluster biosynthetic pathway and suggest new strategies to overcome the loss of cellular FXN that may be relevant to the development of therapeutics for Friedreich’s ataxia.
