G4 self-assembly as an intrinsic nucleic acid function

Anna Varizhuk; Vyacheslav Severov; Galina Pozmogova

Volume 9, Issue 2 , February 2018, Pages 91-96

https://doi.org/10.5185/amlett.2018.2003

Abstract
  It is now commonly acknowledged that G-rich polynucleotide sites can fold into G-quadruplex (G4) structures in vivo. In terms of molecular programming, the G4-folding propensity can be regarded as a build-in nucleic acid function with multiple implications for genomic regulation. Here we review several ...  Read More
