Transferrin 1 Functions in Iron Trafficking and Genetically Interacts with Ferritin in Drosophila melanogaster

？ Transferrin 1 (Tsf1) participates in iron trafficking in Drosophila melanogaster ？ Tsf1 knockdown leads to iron accumulation in the gut but deficiency in the fat body ？ Fat body-derived Tsf1 is able to localize to the gut surface ？ Ferritin (Fer1HCH) knockdown could be rescued by Tsf1 knockdow
