詳細
Polyguanylic acid takes up a four-stranded helical structure. It is synthetically produced in Thermus thermophilus from guanosine diphosphate (GDP) and its synthesis is catalyzed by the enzyme polynucleotide phosphorylase.
アプリケーション
Polyguanylic acid (PolyG) is used to study the effects of ionizing radiation on formation and stability of G-quadruplex structures and as a target molecule for physicochemical studies of electronic excitation (vibrational spectra) of guanosine.
Polyguanylic acid potassium salt has been used:
- as a ligand for surface neuropilin-1 (NRP1) for internalization studies
- for intercalation studies with trisubstituted and disubstituted triazole-linked phenyl derivatives CL41, CL42 and CL2r50 using voltammetry method
- as a synthetic polynucleotide for agarose gel electrophoresis analysis
生物化学的／生理学的作用
Polyguanylic acid acts as a ligand for scavenger receptor and reduces the surface expression neuropilin-1 in endothelial cells.

Chromosomes in vertebrates are protected at both ends by telomere DNA composed of tandem (TTAGGG)n repeats. DNA replication produces a blunt-ended leading strand telomere and a lagging strand telomere carrying a single-stranded G-rich overhang at its end. The G-rich strand
