Available in PDF, EPUB and Kindle. Book excerpt: After transcription in the nucleus, RNA binding proteins (RBPs) recognize cis-regulatory RNA elements within pre-mRNA sequence to form mRNA-protein (mRNP) complexes. Similarly to DNA binding proteins such as transcription factors that regulate gene expression by binding to DNA elements in the promoters of genes, RBPs regulate the fate of target RNAs by interacting with specific sequences or RNA secondary structural features within the transcribed RNA molecule. The set of functional RNA elements recognized by RBPs within target RNAs and which control the temporal, functional and spatial dynamics of the target RNA define a putative “mRNP code”. These cis-regulatory RNA elements can be found in the 5’ and 3’ untranslated regions (UTRs), introns, and exons of all protein-coding genes. RNA elements in 5’ and 3’ UTRs are frequently involved in targeting RNA to specific cellular compartments, affecting 3’ end formation, controlling RNA stability and regulating mRNA translation. RNA elements in introns and exons are known to function as splicing enhancers or silencers during the splicing process from pre-mRNA to mature mRNA. This book provides case studies of RNA binding proteins that regulate aspects of RNA processing that are important for fundamental understanding of diseases and development. Chapters include systems-level perspectives, mechanistic insights into RNA processing and RNA Binding proteins in genetic variation, development and disease. The content focuses on systems biology and genomics of RNA Binding proteins and their relation to human diseases.

Available in PDF, EPUB and Kindle. Book excerpt: The work described in this book is an excellent example of interdisciplinary research in systems biology. It shows how concepts and approaches from the field of physics can be efficiently used to answer biological questions and reports on a novel methodology involving creative computer-based analyses of high-throughput biological data. Many of the findings described in the book, which are the result of collaborations between the author (a theoretical scientist) and experimental biologists and between different laboratories, have been published in high-quality peer-reviewed journals such as Molecular Cell and Nature. However, while those publications address different aspects of post-transcriptional gene regulation, this book provides readers with a complete, coherent and logical view of the research project as a whole. The introduction presents post-transcriptional gene regulation from a distinct angle, highlighting aspects of information theory and evolution and laying the groundwork for the questions addressed in the subsequent chapters, which concern the regulation of the transcriptome as the primary functional carrier of active genetic information.

Available in PDF, EPUB and Kindle. Book excerpt: The work reported in this book represents an excellent example of how creative experimentation and technology development, complemented by computational data analysis, can yield important insights that further our understanding of biological entities from a systems perspective. The book describes how the study of a single RNA-binding protein and its interaction sites led to the development of the novel ‘protein occupancy profiling’ technology that for the first time captured the mRNA sequence space contacted by the ensemble of expressed RNA binders. Application of protein occupancy profiling to eukaryotic cells revealed that extensive sequence stretches in 3’ UTRs can be contacted by RBPs and that evolutionary conservation as well as negative selection act on protein-RNA contact sites, suggesting functional importance. Comparative analysis of the RBP-bound sequence space has the potential to unravel putative cis-acting RNA elements without a priori knowledge of the bound regulators. Here, Dr. Munschauer provides a comprehensive introduction to the field of post-transcriptional gene regulation, examines state-of-the-art technologies, and combines the conclusions from several journal articles into a coherent and logical story from the frontiers of systems-biology inspired life science. This thesis, submitted to the Department of Biology, Chemistry and Pharmacy at Freie Universität Berlin, was selected as outstanding work by the Berlin Institute for Medical Systems Biology at the Max-Delbrueck Center for Molecular Medicine, Germany.

Download or read book Regulation by RNA binding Proteins written by Maria Sarah Alexis and published by . This book was released on 2019 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA-binding proteins (RBPs) regulate all aspects of RNA metabolism, such as splicing, localization, translation, and degradation. RNA processing is a critical component of gene expression regulation, and adaptive changes in RNA processing underlie many phenotypic differences between species. RBPs regulate RNA processing by recognizing RNA sequence elements (motifs) within RNAs. Studying the determinants of these RBP:RNA interactions is therefore key to understanding how RBPs select their targets, and how RNA processing evolves over time. This thesis presents three chapters revolving around these questions. First, I present a large-scale analysis of the evolution of gene expression across tissues, species, and studies. This study differs from previous studies in its usage of inter-sample distances to model gene expression divergence, a method that allowed us to reconcile disparate findings in the field. Second, I present a comprehensive study of the affinity landscapes of 78 human RBPs using RNA Bind-N-Seq (RBNS), an unbiased assay that determines the sequence, structure, and context preferences of RBPs. Integrated analysis of all 78 motifs reveals an unexpectedly low diversity of RNA motifs, implying frequent convergence of binding specificity towards a relatively small set of RNA motifs, many with low compositional complexity. Offsetting this trend, RBPs show extensive preferences for contextual features distinct from short linear motifs, including spaced "bipartite" motifs, biased flanking nucleotide composition, and bias away from or toward RNA structure. These results emphasize the importance of contextual features in RNA recognition, which likely enable targeting of distinct subsets of transcripts by different RBPs that recognize the same linear motif. Lastly, I compile a catalog of all known RBP specificities and examine their conservation patterns, in vivo binding patterns, and evolutionary trajectories across species. This work demonstrates that RNA regulation can be well conserved despite rapid evolution of RBP binding sites, and highlights mechanisms that may contribute to this robustness. This phenomenon is well-characterized for transcriptional regulation at promoters, but has not well been described for RNA regulation. Taken together, these studies advance our understanding of RBP target selection and how it evolves over time, thereby furthering our understanding of the basic mechanisms that govern gene regulation.

Download or read book Biochemical and Functional Characterization of Human RNA Binding Proteins written by Peter Dale Freese and published by . This book was released on 2018 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA not only shuttles information between DNA and proteins but also carries out many other essential cellular functions. Nearly all steps of an RNA’s life cycle are controlled by approximately one thousand RNA binding proteins (RBPs) that direct RNA splicing, cleavage and polyadenylation, localization, translation, and degradation. Despite the central role of RBPs in RNA processing and gene expression, they have been less well studied than DNA binding proteins, in part due to the historical dearth of technologies to probe RBP binding and activity in a high-throughput, comprehensive manner. In this thesis, I describe the affinity landscapes of the largest set of human RBPs to date elucidated through a highthroughput version of RNA Bind-N-Seq (RBNS), an unbiased in vitro assay that determines the primary sequence, secondary structure, and contextual preferences of an RBP. The 78 RBPs bound an unexpectedly low diversity of RNA motifs, implying convergence of binding specificity toward a small set of RNA motifs characterized by low compositional complexity. Offsetting the low diversity of sequence motifs, extensive preferences for contextual features beyond short linear motifs were observed, including bipartite motifs, flanking nucleotide content, and preference for or against RNA structure. These features likely refine which motif occurrences are selected in cells, enabling RBPs that bind the same linear motif to act on distinct subsets of transcripts. Additionally, RBNS data is integrated with complementary in vivo binding sites from enhanced crosslinking and immunoprecipitation (eCLIP) and functional (RNAi/RNA-seq) data produced through collaborative efforts with the ENCODE consortium. These data enable creation of “RNA maps” of RBP activity in pre-mRNA splicing and gene expression levels, either with (eCLIP) or without (RBNS) crosslinking-based assays. The mapping and characterization of RNA elements recognized by over 200 human RBPs is also presented in two human cell lines, K562 and HepG2 cells. Together, these novel data augment the catalog of functional elements encoded in the human genome to include those that act at the RNA level and provide a basis for how RBPs select their RNA targets, a fundamental requirement in more fully understanding RNA processing mechanisms and outcomes.

Download or read book RNA Protein Interaction Protocols written by Susan R. Haynes and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular characterization of RNA and its interactions with proteins is an important and exciting area of current research. Organisms utilize a variety of RNA–protein interactions to regulate the expression of their genes. This is particularly true for eukaryotes, since newly synthesized messenger RNA must be extensively modified and transported to the cytoplasm before it can be used for protein synthesis. The realization that posttranscriptional processes are critical components of gene regulation has sparked an explosion of interest in both stable ribonucleoprotein (RNP) complexes and transient RNA–protein interactions. RNA is conformationally flexible and can adopt complex structures that provide diverse surfaces for interactions with proteins. The fact that short RNA molecules (aptamers; see Chapter 16) can be selected to bind many different types of molecules is evidence of the structural variability of RNA. RNA molecules are rarely entirely single- or double-stranded, but usually contain multiple short duplexes interrupted by single-stranded loops and bulges; in some RNAs, such as tRNAs, the short duplexes stack on each other. Further variability is generated by the presence of non-Watson-Crick base pairs, modified nucleotides, and more complex structures, such as pseudoknots and triple-strand interactions.

Download or read book RNA Binding Proteins written by Kathryn Sandberg and published by Springer. This book was released on 2001-12-31 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA binding proteins are an exciting area of research in gene regulation. A multitude of RNA-protein interactions are used to regulate gene expression including pre-mRNA splicing, polyadenylation, editing, transport, cytoplasmic targeting, translation and mRNA turnover. In addition to these post-transcriptional processes, RNA-protein interactions play a key role in transcription as illustrated by the life cycle of retroviruses. Unlike DNA, the structure of RNA is highly variable and conformationally flexible, thus creating a number of unique binding sites and the potential for complex regulation by RNA binding proteins. Although there is a wide range of topics included in this volume, general themes have been repeated, highlighting the overall integrative nature of RNA binding proteins. The chapters have been separated into three different sections: Translational Control; mRNA Metabolism; and Hormonal and Homeostatic Regulation. The chapters of this volume were written with the seasoned investigator and student in mind. Summaries of key concepts are reviewed within each chapter as well as guiding questions that can be used to stimulate class discussions. The Editors of this volume hope that this compendium educates, enthralls, and stimulates the readers to look to the future possibilities in this rapidly evolving field.

Download or read book Understanding Regulation of Messenge Ribonucleic Acid by Ribonucleic Acid Binding Proteins written by Alexander De Jong Robertson and published by . This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Posttranscriptional regulation of mRNA by RNA-binding proteins plays key roles in regulating the transcriptome over the course of development, between tissues and in disease states. The specific interactions between mRNA and protein are controlled by the proteins' inherent affinities for different RNA sequences as well as other features such as translation and RNA structure which affect the accessibility of mRNA. The stabilities of mRNA transcripts are regulated by nonsense-mediated mRNA decay (NMD), a quality control degradation pathway. In this thesis, I present a novel method for high throughput characterization of the binding affinities of proteins for mRNA sequences and an integrative analysis of NMD using deep sequencing data. This thesis describes RNA Bind-n-Seq (RBNS), which comprehensively characterizes the sequence and structural specificity of RNA binding proteins (RBPs), and application to the developmentally-regulated splicing factors RBFOX2, MBNL1 and CELF1/CUGBP1. For each factor, the canonical motifs are recovered as well as additional near-optimal binding motifs. RNA secondary structure inhibits binding of RBFOX2 and CELF1, while MBNL1 favors unpaired Us but tolerates C/G pairing in UGC-containing motifs. In a project investigating how NMD shapes the embryonic transcriptome, this thesis presents integrated genome-wide analyses of UPF1 binding locations, NMD-regulated gene expression, and translation in murine embryonic stem cells (mESCs). Over 200 direct UPF1 binding targets are identified using crosslinking/immunoprecipitation-sequencing (CLIP-seq). Results from ribosome foot printing show that actively translated upstream open reading frames (uORFs) are enriched in transcription factor mRNAs and predict mRNA repression by NMD, while poorly translated mRNAs escape repression.
