5′-UTR RNA G-quadruplexes: translation regulation and targeting
RNA structures in the untranslated regions (UTRs) of mRNAs influence post-transcriptional regulation of gene expression. Much of the knowledge in this area depends on canonical double-stranded RNA elements. There has been considerable recent advancement of our understanding of guanine(G)-rich nucleic acids sequences that form four-stranded structures, called G-quadruplexes. While much of the re...

متن کاملRNA G-quadruplexes and their potential regulatory roles in translation
DNA guanine (G)-rich 4-stranded helical nucleic acid structures called G-quadruplexes (G4), have been extensively studied during the last decades. However, emerging evidence reveals that 5'- and 3'-untranslated regions (5'- and 3'-UTRs) as well as open reading frames (ORFs) contain putative RNA G-quadruplexes. These stable secondary structures play key roles in telomere homeostasis and RNA meta...
متن کاملHuman telomere, oncogenic promoter and 5′-UTR G-quadruplexes: diverse higher order DNA and RNA targets for cancer therapeutics
Guanine-rich DNA sequences can form G-quadruplexes stabilized by stacked G-G-G-G tetrads in monovalent cation-containing solution. The length and number of individual G-tracts and the length and sequence context of linker residues define the diverse topologies adopted by G-quadruplexes. The review highlights recent solution NMR-based G-quadruplex structures formed by the four-repeat human telom...
متن کاملPredictable suppression of gene expression by 5′-UTR-based RNA quadruplexes
Four-stranded DNA and RNA quadruplexes or G4 motifs are non-B DNA conformations that are presumed to form in vivo, although only few explicit evidence has been reported. Using bioinformatics the presence of putative DNA G-quadruplexes within critical promoter regions has been demonstrated and a regulatory role in transcription has been suspected. However, in genomic DNA the presence of the comp...
