New scoring system to identify RNA G-quadruplex folding
G-quadruplexes (G4s) are non-canonical structures involved in many important cellular processes. To date, the prediction of potential G-quadruplex structures (PG4s) has been based almost exclusively on the sequence of interest agreeing with the algorithm Gx-N-1-7-Gx-N1-7-Gx-N1-7-Gx (where x ≥ 3 and N = A, U, G or C). However, many sequences agreeing with this algorithm do not form G4s and are c...

متن کاملG4RNA: an RNA G-quadruplex database
G-quadruplexes (G4) are tetrahelical structures formed from planar arrangement of guanines in nucleic acids. A simple, regular motif was originally proposed to describe G4-forming sequences. More recently, however, formation of G4 was discovered to depend, at least in part, on the contextual backdrop of neighboring sequences. Prediction of G4 folding is thus becoming more challenging as G4 outl...
متن کاملOverview of the RNA G-quadruplex structures.
G-quadruplexes are non-canonical secondary structures which may be formed by guanine rich sequences, both in vitro and in living cells. The number of biological functions assigned to these structural motifs has grown rapidly since the discovery of their involvement in the telomere maintenance. Knowledge of the G-quadruplexes' three-dimensional structures plays an important role in understanding...
متن کاملAn RNA Hairpin to G-Quadruplex Conformational Transition
RNA molecules can fold into noncanonical structures such as the four-stranded structures known as G-quadruplexes. G-quadruplexes in the transcriptome have recently emerged as relevant regulatory elements of gene expression. Conformational transitions in RNA molecules offer an important way to regulate their biological functions. Here we report on the competition between a canonical hairpin stru...
