SHAPE Profiling to Probe Group II Intron Conformational Dynamics During Splicing
- 61 Downloads
手机体育投注平台Selective 2′-hydroxyl acylation analyzed by primer extension (SHAPE) is a widely used technique for studying the structure and function of RNA molecules. It characterizes the flexibility of single nucleotides in the context of the local RNA structure. Here we describe the application of SHAPE-MaP (mutational profiling) to study different conformational states of the group II intron during the self-splicing reaction.
