Examining the relationship between RNA function and motion using nuclear magnetic resonance.

The biological function of proteins and nucleic acids relies on their complex structures, yet dynamics provides an additional layer of functional adaptability. Numerous studies have demonstrated that RNA is only able to perform the multitude of functions for which it is responsible by readily changing its conformation in response to binding of proteins or small molecules. Examination of RNA dynamics is therefore essential to understanding its biological function. Nuclear magnetic resonance (NMR) has emerged as a leading technique for the examination of RNA motion and conformational transitions. It can examine domain motions as well as motion with atomic level resolution over a wide range of time scales. This review examines how NMR spectroscopy can be applied to examine the relationship between function and dynamics in RNA.
