Structural basis of DNA quadruplex recognition by an acridine drug.
The crystal structure of a complex between the bimolecular human telomeric quadruplex d(TAGGGTTAGGGT)2 and the experimental anticancer drug BRACO-19, has been determined, to 2.5 A resolution. The binding site for the BRACO-19 molecule is at the interface of two parallel-folded quadruplexes, sandwiched between a G-tetrad surface and a TATA tetrad, and held in the site by networks of water molecu...
متن کاملStructural studies of oligonucleotides containing G-quadruplex motifs using AFM.
G-quadruplex DNAs are cyclic arrays of four guanine bases binding by Hoogsteen hydrogen bonds, found in the telomeric regions of chromosomes and in transcriptional regulatory regions of several important oncogenes. Here, we used high resolution atomic force microscopy (AFM) to observe a specific guanine (G) tetrad mediated complex formation of oligonucleotides containing a G-quadruplex motifs (...
متن کاملNucleic acid clamp-mediated recognition and stabilization of the physiologically relevant MYC promoter G-quadruplex
The MYC proto-oncogene is upregulated, often at the transcriptional level, in ∼80% of all cancers. MYC's promoter is governed by a higher order G-quadruplex (G4) structure in the NHE III1 region. Under a variety of conditions, multiple isoforms have been described to form from the first four continuous guanine runs (G41-4) predominating under the physiologically relevant supercoiled conditions....
