Abstract

Ferritin plays a key role in determining the intracellular fate of iron and is highly regulated by the iron status of the cell. We have identified a cis-acting element in the transcribed but nontranslated 5' leader sequence of human ferritin heavy-chain mRNA. In transiently transfected murine fibroblasts, the presence of a 157-nucleotide region of the 5' leader sequence was found to be necessary for iron-dependent regulation of ferritin biosynthesis. Further, this 5' leader region is sufficient to transfer iron-mediated translational control to the expression of a heterologous gene product, chloramphenicol acetyltransferase.

  • In 1987, investigators observed that conserved sequences in the 5' UTRs of both H- and L-ferritin mRNAs were needed to control a ready but quiescent pool of ferritin mRNA.

    “In 1987, investigators observed that conserved sequences in the 5Ј untranslated regions (UTRs) of both H-and L-ferritin mRNAs were needed to control a ready but quiescent pool of ferritin mRNA in the cell, which could quickly be mobilized to produce ferritin protein when iron was abundant.22,23”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
