Area of Research Interest
Our research has focused on iron-sulfur cluster biogenesis and iron homeostasis. While sulfur in iron-sulfur clusters in proteins is derived from L-cysteine via cysteine desulfurase, the specific iron donor has not been fully understood. We aim to illustrate the mechanism by which the intracellular iron is mobilized and delivered for iron-sulfur cluster biogenesis in proteins. We have also been interested in the redox regulation of iron-sulfur proteins in key physiological processes.
