The function of ENSG00000087086 (FTL, ferritin light chain) is as follows. 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). Delivery to lysosomes by the cargo receptor NCOA4 for autophagic degradation and release or iron (PubMed:24695223). {ECO:0000250, ECO:0000269|PubMed:19923220, ECO:0000269|PubMed:20159981, ECO:0000269|PubMed:24695223}.
