项目摘要

Project Summary Proper control of gene expression is essential for life. While substantial advances have been made in the discovery of DNA sequences and transcription factors that act combinatorially to regulate transcription, much less is known about later steps in the gene expression program. Nevertheless, it is now clear that substantial regulation of gene expression occurs post-transcriptionally, in pre-mRNA splicing, RNA localization, translation, and RNA decay, and in the coordination of RNAs by RNA binding proteins (RBPs), microRNAs, and RNA chemical modifications. While many sequence motifs are known to mediate post-transcriptional regulation, RNA secondary structures that govern access to these motifs are much less well understood. The long term goal of this project is to enable structural characterization of RNAs on a genome-wide scale. First, we will apply a recently developed method to map secondary structures of most human RNAs in living cells. Second, we will develop methods to follow the fate of RNA secondary structures through the RNA life cycle. Third, we will develop high throughput methods to perturb and test functions of RNA structures. This integrated pipeline of new technologies will enable investigators to identify and decode regulatory RNA elements in the genome with unprecedented speed and accuracy.

项目摘要适当控制基因表达对生命至关重要。尽管在发现与转录作用的DNA序列和转录因子的发现中已经取得了重大进展，但对基因表达程序中的以后步骤的了解少得多。然而，现在很明显，基因表达的大量调节是在转录后发生的，在MRNA剪接，RNA定位，翻译和RNA衰减中，以及通过RNA结合蛋白（RBPS），microRNAS和RNA化学修饰的RNA结合蛋白（RBPS）和RNA对RNA的协调。尽管已知许多序列基序都介导了转录后调节，但控制这些基序的访问的RNA二级结构知之甚少。该项目的长期目标是在全基因组范围内实现RNA的结构表征。首先，我们将采用最近开发的方法来绘制活细胞中大多数人RNA的二级结构。其次，我们将开发通过RNA生命周期遵循RNA二级结构命运的方法。第三，我们将开发高吞吐量方法来驱动和测试RNA结构的功能。这种新技术的综合管道将使研究人员能够以前所未有的速度和准确性来识别和解码基因组中的调节RNA元素。
