Abstract Guanine-quadruplexes (G4s) are non-canonical four-stranded structures that can
be formed in guanine (G) rich nucleic acid sequences. A great number of G-rich sequences …

SUMMARY RNA G-quadruplex (rG4) secondary structures are proposed to play key roles in
fundamental biological processes that include the modulation of transcriptional, co …

Abstract G-quadruplexes (G4s) are non-classical DNA or RNA secondary structures that
have been first observed decades ago. Over the years, these four-stranded structural motifs …

RNA G-quadruplexes (RG4s) are four-stranded structures known to control gene expression
mechanisms, from transcription to protein synthesis, and DNA-related processes. Their …

Abstract RNA G-quadruplexes (RG4s) are non-canonical, disease-associated post-
transcriptional regulators of gene expression whose functions are driven by RNA-binding …

Abstract G-quadruplexes (G4s) are extremely stable DNA or RNA secondary structures
formed by sequences rich in guanine. These structures are implicated in many essential …

Four-stranded G-quadruplex (G4) structures form from guanine-rich tracts, but the extent of
their formation in cellular RNA and details of their role in RNA biology remain poorly defined …

Abstract RNA G-quadruplexes (G4s) are formed by G-rich RNA sequences in protein-coding
(mRNA) and non-coding (ncRNA) transcripts that fold into a four-stranded conformation …

Guanine-rich RNA sequences can fold into four-stranded structures, termed G-quadruplexes
(G4-RNAs), whose biological roles are poorly understood, and in vivo existence is debated …

DNA and RNA can adopt various secondary structures. Four-stranded G-quadruplex (G4)
structures form through self-recognition of guanines into stacked tetrads, and considerable …
