Iron sensing and signalling
WebAbstract. To ensure proper utilization of iron and avoid its toxicity, cells are equipped with iron-sensing proteins to maintain cellular iron homeostasis. We showed previously that NCOA4, a ferritin-specific autophagy adapter, intricately regulates the fate of ferritin; upon binding to Fe 3+, NCOA4 forms insoluble condensates and regulates ...
