Extended Data Fig. 2: Circular dichroism (CD) spectra of the three G4 sequences in the absence or presence of tag-free YY1 protein.
From: YY1 interacts with guanine quadruplexes to regulate DNA looping and gene expression
a-c, CD spectra of cMYC G4 (a), YY1 (b) and cMYC G4-YY1 complex (c). d-f, Comparison of CD spectra for G4 probes in the presence or absence of YY1 protein. The CD spectra for the G4 probes in the presence of YY1 protein were obtained by subtracting the CD spectrum of the YY1 protein from the composite spectra of the protein-G4 DNA complexes.
