UniProtKB accession:  P09528

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Stores iron in a soluble, non-toxic, readily available form (By similarity). Important for iron homeostasis (By similarity). Has ferroxidase activity (By similarity). Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation (By similarity). Also plays a role in delivery of iron to cells (PubMed:19154717). Mediates iron uptake in capsule cells of the developing kidney (PubMed:19154717). Degraded to release iron upon autophagy activation by nutrient starvation (PubMed:25327288).
