RNA-Protein Interactions : A Practical Approach


Book Description

RNA-protein interactions play a fundamental role in gene expression and protein synthesis. Recent research into the role of RNA in cells has elucidated many more vital interactions with proteins. This book provides an up-to-date and comprehensive guide to a wide range of laboratory procedures to investigate the interactions between RNA and proteins. - ;RNA-protein interactions play a vital role in gene transcription and protein expression. Interactions such as the synthesis of mRNA by RNA polymerases, to the essential modification of RNA by the proteins of the spliceosome complex, and the highly catalytic action of the ribosome in protein synthesis, are established as being fundamental to the function of RNA. Recent research into, for example, the role of RNA as a catalyst, has elucidated many more interactions with proteins that are vital to cell function. RNA - Protein Interactions: A Practical Approach provides a clear and comprehensive guide to the experimental procedures used in studying RNA - protein interactions. The approaches covered range from those initially used to detect a novel RNA-protein interaction, various biochemical and genetic approaches to purifying and cloning RNA binding proteins, through to methods for an in depth analysis of the structural basis of the interaction. The volume includes a number of procedures that have not previously been covered in this type of manual. These include the production of site-specifically modified RNAs by enzymatic and chemical methods and in vivo screening for novel RNA - protein interactions in yeast and E. coli . This is the first volume to gather in one place this wide array of approaches for studying RNA - protein interactions. As is customary for the Practical Approach series, the writing is characterized by a clear explanatory style with many detailed protocols. This informative book will be a valuable aid to laboratory workers in biochemistry and molecular biology - graduate students, postdoctoral and senior scientists - whose research encompasses this field. -

RNA'Protein Interaction Protocols


Book Description

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.

Protein-Protein Interactions


Book Description

Proteins are indispensable players in virtually all biological events. The functions of proteins are coordinated through intricate regulatory networks of transient protein-protein interactions (PPIs). To predict and/or study PPIs, a wide variety of techniques have been developed over the last several decades. Many in vitro and in vivo assays have been implemented to explore the mechanism of these ubiquitous interactions. However, despite significant advances in these experimental approaches, many limitations exist such as false-positives/false-negatives, difficulty in obtaining crystal structures of proteins, challenges in the detection of transient PPI, among others. To overcome these limitations, many computational approaches have been developed which are becoming increasingly widely used to facilitate the investigation of PPIs. This book has gathered an ensemble of experts in the field, in 22 chapters, which have been broadly categorized into Computational Approaches, Experimental Approaches, and Others.
