Book Description
Coding regions or exons of most human genes are interrupted by noncoding intervening regions or introns. Removal of nuclear precursor messenger RNA (pre-mRNA) introns by RNA splicing is an essential step in eukaryotic gene expression. Two types of nuclear pre-mRNA introns are known as U2-dependent or major type and U12-dependent or minor type. Nuclear pre-mRNA introns are removed by two distinct sets of ribonucleoprotein complexes or spliceosomes, which are formed by five small nuclear RNAs (snRNAs) for each spliceosome. U6atac and U12 snRNAs are central to U12-dependent spliceosome and play essential roles in the removal of U12-dependent introns. U6atac and U12 snRNAs bind to the 5' splice site and branch site, respectively of an U12-dependent intron. In addition, it has been predicted that, U6atac and U12 snRNAs interact inter-molecularly to form helix I structure, which appears to be an essential element of the minor spliceosome. We have been studying U6atac and U12 inter-molecular base-pairing interaction using an in vivo mutation suppression assay. In this study, we have characterized U6atac and U12 mediated helix I intermolecular interactions and have shown in vivo existence of the predicted structure. In addition, we have also identified a region of U6atac snRNA which appears to be a structural analog of U12 snRNA stem III element. This element is important for the function of U12 snRNA and functions by binding to a RNA binding 65K protein, which is unique to minor spliceosome. We show that, analogous stem-loop of U6atac snRNA also interacts with 65K - RNA binding protein. However, functional significance of this interaction remained unclear. In summation, we have characterized sequential and dynamic RNA-RNA interactions between U4atac-U6atac and U6atac-U12 snRNAs. Our data show that, extensive and obligatory RNA-RNA interactions are critical to the splicing of U12-dependent introns.

Book Description
The origin story and emergence of molecular biology is muddled. The early triumphs in bacterial genetics and the complexity of animal and plant genomes complicate an intricate history. This book documents the many advances, as well as the prejudices and founder fallacies. It highlights the premature relegation of RNA to simply an intermediate between gene and protein, the underestimation of the amount of information required to program the development of multicellular organisms, and the dawning realization that RNA is the cornerstone of cell biology, development, brain function and probably evolution itself. Key personalities, their hubris as well as prescient predictions are richly illustrated with quotes, archival material, photographs, diagrams and references to bring the people, ideas and discoveries to life, from the conceptual cradles of molecular biology to the current revolution in the understanding of genetic information. Key Features Documents the confused early history of DNA, RNA and proteins - a transformative history of molecular biology like no other. Integrates the influences of biochemistry and genetics on the landscape of molecular biology. Chronicles the important discoveries, preconceptions and misconceptions that retarded or misdirected progress. Highlights major pioneers and contributors to molecular biology, with a focus on RNA and noncoding DNA. Summarizes the mounting evidence for the central roles of non-protein-coding RNA in cell and developmental biology. Provides a thought-provoking retrospective and forward-looking perspective for advanced students and professional researchers.

Book Description
The book provides an overview on the different aspects of gene regulation from an mRNA centric viewpoint, including how mRNA is assembled and self-assembles in a complex consisting of RNA and proteins, and how its ability to be translated at the right time and space depends on many processes acting on the mRNAs, leading to a properly folded complex. This book shows how new technologies have led to a better understanding of these processes and their connected diseases.The book is written for scientists in fundamental and applied biomedical research working on different aspects of gene regulation. It is also targeted to an audience that is not implicated in these fields directly, but wants to gain a better understanding of mRNA biology.

Book Description
Revealing the many roles of RNA in regulating gene expression For decades after the discoveries of messenger RNA, transfer RNA, and ribosomal RNA, it was largely assumed that the role of RNA in the cell was limited to shuttling the genomic message, chaperoning amino acids, and toiling in the ribosomes. Eventually, hints that RNA molecules might have regulatory roles began to appear. With the advent of genomics and bioinformatics, it became evident that numerous other RNA forms exist and have specific functions, including small RNAs (sRNA), RNA thermometers, and riboswitches to regulate core metabolic pathways, bacterial pathogenesis, iron homeostasis, quorum sensing, and biofilm formation. All of these functions, and more, are presented in Regulating with RNA in Bacteria and Archaea, written by RNA biologists from around the globe. Divided into eight sections-RNases and Helicases, Cis-Acting RNAs, Cis Encoded Base Pairing RNAs, Trans-Encoded Base Pairing RNAs, Protein Titration and Scaffolding, General Considerations, Emerging Topics, and Resources-this book serves as an excellent resource for established RNA biologists and for the many scientists who are studying regulated cellular systems. It is no longer a fair assumption that gene expression regulation is the provenance of proteins only or that control is exerted primarily at the level of transcription. This book makes clear that regulatory RNAs are key partners along with proteins in controlling the complex interactions and pathways found within prokaryotes.

Book Description
The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.

Book Description
This book offers a comprehensive and detailed overview of various aspects of long non-coding RNAs. It discusses their emerging significance in molecular medicine, ranging from human cancers to cardiovascular and metabolic diseases. Transcriptomic studies have demonstrated that the majority of genomes found in complex organisms are expressed in highly dynamic and cell-specific patterns, producing huge numbers of intergenic, antisense and intronic long non-protein-coding RNAs (lncRNAs). Thousands of lncRNAs have been identified, and unlike mRNA, they have no protein-coding capacity. A large repertoire of ncRNAs, actively transcribed from the mammalian genome, control diverse cellular processes, both in terms of development and diseases, through a variety of gene regulatory mechanisms. IncRNAs have emerged as a new paradigm in epigenetic regulation of the genome. Given its scope, the book will be of particular interest to molecular, chemical, cell and developmental biologists, as well as specialists in translational medicine involved in disease-oriented research. It also offers a valuable resource for in silico experts seeking a deeper understanding of lncRNA expression and function through computational analysis of the NGS data.
