Book Description
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.

Book Description
Gene expression in eukaryotes is regulated at different levels, which need to be coordinated to implement the information in the genome. Now it is clear that post-transcriptional regulation of gene expression such as pre-mRNA splicing, mRNA transport, editing, turnover and translation are as important as the control of transcription. In all aspects

Book Description
In eukaryotes, gene regulation is a complex multilevel process comprising of transcriptional, post-transcriptional, and post-translational control. Although the regulation at transcriptional and post-translational levels is gradually being understood, protein machinery and the mechanisms underlying the post-transcriptional regulation remain to be elucidated. In the first study of this dissertation, I designed and implemented a database of RNA Binding Protein (RBP) Expression and Disease Dynamics (READ-DB: darwin.soic.iupui.edu), a non-redundant, curated database of human RBPs. This RBP knowledge base includes data from different experimental studies providing a one stop portal for understanding the expression, evolutionary trajectories, and disease dynamics of RBPs in the context of post-transcriptional regulatory networks. Despite the existence of several experimental procedures to understand the function of RBPs, a lack of a proper computational method to profile differential occupancy limits the scope of research. In the second study, I built a scalable framework for comparing genome-wide protein occupancy profiles among cell-types data, to uncover alterations in protein-RNA interactomes. diffHunter (github.com/Sasanh/diffHunter), is a window based peak calling and profile comparison method that can efficiently store the base-pair level read information of every given sample in a NoSQL (Not Only SQL) database. It identifies and quantitates the genome-wide binding differences between a pair of samples in two stages: Peak Calling and Differential Binding Identification. Identifying such regions enables us to compare the biologically important regions that differ between two conditions. Finally, I studied A-to- I RNA editing as one of the special functions of an RBPs' family. ADAR family RBPs are the primary driver in the conversion of adenosine to inosine (A-to-I) within mRNA. I developed a Cancer-specific RNA-editing Identification using Somatic variation Pipeline (CRISP: github.com/Sasanh/CRISP) a computational framework for accurate identification of A-to-I editing events contributing to the prognosis and stratification of glioblastoma subtypes as well as the editing events that can serve as molecular classifiers for therapeutic approaches. I proposed two models that explains the cis-regulatory role of A-to-I editing events in noncoding regions in modulating the post-transcriptional regulation of target transcripts in glioblastoma.

Book Description
Detailed characterization of fuzzy interactions will be of central importance for understanding the diverse biological functions of intrinsically disordered proteins in complex eukaryotic signaling networks. In this volume, Peter Tompa and Monika Fuxreiter have assembled a series of papers that address the issue of fuzziness in molecular interactions. These papers provide a broad overview of the phenomenon of fuzziness and provide compelling examples of the central role played by fuzzy interactions in regulation of cellular signaling processes and in viral infectivity. These contributions summarize the current state of knowledge in this new field and will undoubtedly stimulate future research that will further advance our understanding of fuzziness and its role in biomolecular interactions.

Book Description
It has become evident over the last years that abnormalities in RNA processing play a fundamental part in the pathogenesis of neurodegenerative diseases. Cellular viability depends on proper regulation of RNA metabolism and subsequent protein synthesis, which requires the interplay of many processes including transcription, pre--‐mRNA splicing, mRNA editing as well as mRNA stability, transport and translation. Dysfunction in any of these processes, often caused by mutations in the coding and non--‐ coding RNAs, can be very destructive to the cellular environment and consequently impair neural viability. The result of this RNA toxicity can lead to a toxic gain of function or a loss of function, depending on the nature of the mutation. For example, in repeat expansion disorders, such as the newly discovered hexanucleotide repeat expansion in theC9orf72 gene found in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), a toxic gain of function leads to the formation of RNA foci and the sequestration of RNA binding proteins (RBPs). This in return leads to a loss of function of those RBPs, which is hypothesized to play a significant part in the disease progression of ALS and FTD. Other toxicities arising from repeat expansions are the formation of RNA foci, bi--‐directional transcription and production of repeat associated non--‐ATG (RAN) translation products. This book will touch upon most of these disease mechanisms triggered by aberrant RNA metabolism and will therefore provide a broad perspective of the role of RNA processing and its dysfunction in a variety of neurodegenerative disorders, including ALS, FTD, Alzheimer’s disease, Huntington’s disease, spinal muscular atrophy, myotonic dystrophy and ataxias. The proposed authors are leading scientists in the field and are expected to not only discuss their own work, but to be inclusive of historic as well as late breaking discoveries. The compiled chapters will therefore provide a unique collection of novel studies and hypotheses aimed to describe the consequences of altered RNA processing events and its newest molecular players and pathways.

Book Description
RNAs form complexes with proteins and other RNAs. The RNA‐infrastructure represents the spatiotemporal interaction of these proteins and RNAs in a cell‐wide network. RNA Infrastructure and Networks brings together these ideas to illustrate the scope of RNA‐based biology, and how connecting RNA mechanisms is a powerful tool to investigate regulatory pathways. This book is but a taste of the wide range of RNA‐based mechanisms that connect in the RNA infrastructure.

Book Description
Proteins lie at the heart of almost all biological processes and have an incredibly wide range of activities. Central to the function of all proteins is their ability to adopt, stably or sometimes transiently, structures that allow for interaction with other molecules. An understanding of the structure of a protein can therefore lead us to a much improved picture of its molecular function. This realisation has been a prime motivation of recent Structural Genomics projects, involving large-scale experimental determination of protein structures, often those of proteins about which little is known of function. These initiatives have, in turn, stimulated the massive development of novel methods for prediction of protein function from structure. Since model structures may also take advantage of new function prediction algorithms, the first part of the book deals with the various ways in which protein structures may be predicted or inferred, including specific treatment of membrane and intrinsically disordered proteins. A detailed consideration of current structure-based function prediction methodologies forms the second part of this book, which concludes with two chapters, focusing specifically on case studies, designed to illustrate the real-world application of these methods. With bang up-to-date texts from world experts, and abundant links to publicly available resources, this book will be invaluable to anyone who studies proteins and the endlessly fascinating relationship between their structure and function.
