Abstract

Expression of the human transferrin receptor (hTR) and its mRNA is strongly induced by iron deprivation. By measuring transcription elongation rates, levels of hTR-specific nuclear RNA, and mRNA half-lives, we found this regulation to occur posttranscriptionally in the cytoplasm. Analysis of hTR cDNA mutants with deletions in the 3' untranslated region revealed the existence of two distinct domains, both of which are essential for regulation in mouse L cells. The regulated phenotype correlates with the presence of a stem-loop structure predicted by a computer algorithm. Expression of point and deletion mutants affecting the stem-loop confirmed the requirement for this secondary structure in regulation. The 3' untranslated region of hTR cDNA was sufficient to confer iron-dependent regulation on another gene.

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.
