涉及编码和非编码RNA的构象变化形成了遗传调控元件的基础,并为驱动许多基本生命过程提供了重要的复杂性来源。虽然RNA是高度灵活的,但潜在的动力学是稳健的,并且仅限于保留有利的碱基配对和堆叠相互作用的少数构象之间的转换。细胞过程利用RNA的内在动力学行为并将其引导到功能性生产途径的机制是复杂的。多功能和易于整合到各种各样的遗传电路和生化途径表明RNA动力学在细胞过程中的一般和基本作用。
Conformational changes involving coding and non-coding RNAs form the basis for genetic regulatory elements and provide an important source of complexity for driving many fundamental processes of life. While RNA is highly flexible, the underlying dynamics are robust and limited to transitions between the few conformations that preserve favorable base-pairing and stacking interactions. The mechanisms by which cellular processes harness RNA’s intrinsic dynamic behavior and steer it towards functionally productive pathways are complex. Versatile functions and ease of integration into a wide variety of genetic circuits and biochemical pathways suggests a general and fundamental role for RNA dynamics in cellular processes.
