Translational control by 3′-UTR-binding proteins
The regulation of mRNA translation is a major checkpoint in the flux of information from the transcriptome to the proteome. Critical for translational control are the trans-acting factors, RNA-binding proteins (RBPs) and small RNAs that bind to the mRNA and modify its translatability. This review summarizes the mechanisms by which RBPs regulate mRNA translation, with special focus on those bind...
متن کاملTranslational control of mRNAs by 3′-Untranslated region binding proteins
Eukaryotic gene expression is precisely regulated at all points between transcription and translation. In this review, we focus on translational control mediated by the 3'-untranslated regions (UTRs) of mRNAs. mRNA 3'-UTRs contain cis-acting elements that function in the regulation of protein translation or mRNA decay. Each RNA binding protein that binds to these cis-acting elements regulates m...
متن کاملConservation of the C.elegans tra-2 3'UTR translational control.
The Caenorhabditis elegans sex-determination gene, tra-2, is translationally regulated by two 28 nt elements (DREs) located in the 3'UTR that bind a factor called DRF. This regulation requires the laf-1 gene activity. We demonstrate that the nematode Caenorhabditis briggsae tra-2 gene and the human oncogene GLI are translationally regulated by elements that are functionally equivalent to DREs. ...
متن کاملForebrain and midbrain development requires epiblast-restricted Otx2 translational control mediated by its 3' UTR.
Otx genes play an important role in brain development. Previous mouse models suggested that the untranslated regions (UTRs) of Otx2 mRNA may contain regulatory element(s) required for its post-transcriptional control in epiblast and neuroectoderm. In order to study this, we have perturbed the 3' UTR of Otx2 by inserting a small fragment of DNA from the lambda phage. Otx2(lambda) mutants exhibit...
متن کاملSTAU1 binding 3' UTR IRAlus complements nuclear retention to protect cells from PKR-mediated translational shutdown.
For a number of human genes that encode transcripts containing inverted repeat Alu elements (IRAlus) within their 3' untranslated region (UTR), product mRNA is efficiently exported to the cytoplasm when the IRAlus, which mediate nuclear retention, are removed by alternative polyadenylation. Here we report a new mechanism that promotes gene expression by targeting mRNAs that maintain their 3' UT...
