Gene Snapshot
Ferritin 1 heavy chain homologue (Fer1HCH) encodes one of two subunits of the major iron storage complex, the ferritin molecule. In insects, ferritin is assembled from 12 Fer1HCH and 12 Fer2LCH subunits and can be found in the secretory pathway of cells and in hemolymph. The product of Fer1HCH has ferroxidase activity required for iron loading into ferritin and is essential for embryogenesis. [Date last reviewed: 2019-03-07]

Gene Group (FlyBase)
FERRITINS -
Ferritins (FER) function as main iron storage proteins and regulate iron homeostasis. Cytoplasmic ferritin is a heteropolymer of heavy and light chain subunits encoded by Fer1HCH and Fer2LCH, respectively. Mitochondrial ferritin exists as a homopolymer of Fer3HCH proteins. Heavy chain homologs (Fer1HCH and Fer3HCH) have ferroxidase activity, essential for the incorporation of iron into the ferritin shell. Light chain homologs (Fer2LCH) play a role in the nucleation of the ferritin iron cores. (Adapted from FBrf0190848 and PMID:20230873).
FERROXIDASES -
Ferroxidases are a group of oxidoreductases that catalyze the oxidation of ferrous (Fe+2) iron to ferric (Fe+3) iron.

    Additional comments
    Other Comments
    Iron availability alters the distribution of different Fer1HCH RNA alternative splice variants.
    Conserved ferritin PCR primers are used to isolate a cDNA clone that contains the complete coding sequence for a ferritin subunit. Additional 5' sequence obtained by RACE method reveals the presence of a putative iron regulatory element. The deduced amino acid sequence contains a signal sequence that closely resembles the sequence from A.aegypti ferritin.
    Encodes the 25kD and 26kD ferritin subunits.
