Iron-sulfur clusters are co-factors that are involved in several biological processes, such as oxidative phosphorylation, enzymatic reactions, and DNA replication and repair. Scientists from the National Institutes of Health (NIH) have presented a study regarding the clinical manifestations associated with a novel neuromuscular disease gene – CIAO1 – which encodes probable cytosolic iron-sulfur protein assembly protein CIAO1 and is an essential member in the cytoplasmic iron-sulfur assembly machinery.
