The global folding of four-way helical junctions in RNA, including that in U1 snRNA
Helical junctions are important elements in the architecture of folded RNA molecules. The global geometry of fully base-paired four-way junctions between RNA helices has been analyzed by comparative gel electrophoresis. Junctions appear to fold by pairwise coaxial helical stacking in one of two possible stereochemically equivalent isomers based upon alternative selections of stacking partners. ...

15 صفحه اولSingle-molecule studies of DNA and RNA four-way junctions.
Branched helical junctions are common in nucleic acids. In DNA, the four-way junction (Holliday junction) is an essential intermediate in homologous recombination and is a highly dynamic structure, capable of stacking conformer transitions and branch migration. Our single-molecule fluorescence studies provide unique insight into the energy landscape of Holliday junctions by visualizing these pr...
متن کاملU1 snRNA Rewrites the “Script”
Expression of eukaryotic mRNAs requires the collaboration of a host of RNA processing factors acting upon the transcript. Berg et al. describe how a pre-mRNA splicing factor modulates the activity of the polyadenylation machinery to regulate mRNA length, with important implications for isoform expression in activated neuronal and immune cells.
