The elaborate control of biogenesis and turnover is essential for circular RNAs (circRNAs) to exert their functions properly in eukaryotic cells, whereas how circRNAs are degraded remains unclear. A recent study by Fischer et al. reveals a novel structure-mediated circRNA decay that selectively degrades highly structured RNAs by UPF1 and G3BP1.
真核细胞中精确的生物发生和周转控制对于环状 RNA（circRNA）发挥其功能至关重要，然而circRNA 的降解机制仍不清楚。Fischer 等人的一项最新研究揭示了一种新的结构介导的 circRNA 降解机制，该机制通过 UPF1 和 G3BP1 选择性地降解高度结构化的 RNA。
