Analysis of the Factors Affecting the Configuration of the Anti-parallel G-quadruplex Formed by 22-nt Telomere RNA Fragments / 中国生物化学与分子生物学报

ABSTRACT

G-quadruplexes with different conformations often exhibit different binding abilities to proteins and play different physiological functions. It is of great significance to analyze the factors affecting the configuration of G-quadruplex to explore its physiological function. Different from DNA, RNA sequences have shown parallel G-quadruplex structures in previous reports. However, we found that the only RNA sequence, the 22-nt telomere RNA fragment (ORN-N, A
