Regulation of gene expression by RNA-binding proteins and microRNAs
Abstract/Contents
- Abstract
- Circumstantial evidence suggests vast post-transcriptional regulatory networks in eukaryotes. There are scores of examples of mRNAs with rich post-transcriptional lives, and dozens of RNA-binding proteins and noncoding RNAs are suggested to have regulatory functions. While eukaryotic genomes encode hundreds of RNA-binding proteins and metazoans also encode dozens to hundreds of regulatory noncoding RNAs, few RNA-binding proteins or regulatory noncoding RNAs have been studied systematically, leaving unanswered basic questions about the scope and organization of post-transcriptional regulation in any eukaryote. First, I present studies aimed at uncovering some of the basic principles of post-transcriptional regulation in eukaryotes, via searching for the RNA targets of 40 proteins in the yeast Saccharomyces cerevisiae: a selective sample of the approximately 600 annotated and predicted RBPs as well as several proteins not annotated as RBPs. Second, I present a simple biochemical approach to identify direct targets of specific microRNAs, important noncoding regulatory RNAs, that regulate protein synthesis of most mammalian mRNAs. Third, I present experiments that uncover the magnitude and respective contributions of translational repression and mRNA decay of microRNA-mediated regulation. These studies apply simple, yet powerful approaches to systematically dissect various aspects of post-transcriptional regulation and uncover a wealth of novel information regarding regulation by RNA-binding proteins and microRNAs.
