| UniProt functional annotation for P02791 | |||
| UniProt code: P02791. |
| Organism: | Equus caballus (Horse). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Laurasiatheria; Perissodactyla; Equidae; Equus. | |
| Function: | Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney (By similarity). {ECO:0000250}. | |
| Subunit: | Oligomer of 24 subunits. There are two types of subunits: L (light) chain and H (heavy) chain. The major chain can be light or heavy, depending on the species and tissue type. The functional molecule forms a roughly spherical shell with a diameter of 12 nm and contains a central cavity into which the insoluble mineral iron core is deposited. | |
| Miscellaneous: | In horse spleen the light chain is the major chain. | |
| Similarity: | Belongs to the ferritin family. {ECO:0000305}. | |
