Biological basis for restriction of microRNA targets to the 3′ untranslated region in mammalian mRNAs

Abstract

MicroRNAs (miRNAs) interact with target sites located in the 3′ untranslated regions (3′ UTRs) of mRNAs to downregulate their expression when the appropriate miRNA is bound to target mRNA. To establish the functional importance of target-site localization in the 3′ UTR, we modified the stop codon to extend the coding region of the transgene reporter through the miRNA target sequence. As a result, the miRNAs lost their ability to inhibit translation but retained their ability to function as small interfering RNAs in mammalian cells in culture and in vivo. The addition of rare but not optimal codons upstream of the extended opening reading frame (ORF) made the miRNA target site more accessible and restored miRNA-induced translational knockdown. Taken together, these results suggest that active translation impedes miRNA-programmed RISC association with target mRNAs and support a mechanistic explanation for the localization of most miRNA target sites in noncoding regions of mRNAs in mammals.

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.
