G protein-coupled receptors (GPCRs) are heptahelical transmembrane receptors that convert extra-cellular stimuli into intra-cellular signaling, and ultimately into biological responses. Since GPCRs are natural targets for approximately 40% of all modern medicines, it is not surprising that they have been the subject of intense research. Notwithstanding the amount of data generated over the years, discovering ligands of these receptors with optimal therapeutic properties is not straightforward and has certainly been hampered for years by the lack of high-resolution structural information about these receptors. Luckily, there has been a steady increase of high-resolution crystal structures of these receptors since 2007, and this information, integrated with dynamic inferences from computational and experimental methods, holds great potential for the discovery of new, improved drugs. This book, which provides, for the first time, state-of-the-art views on modeling and simulation of GPCRs, is divided into 4 parts. In the first part, the impact of currently available GPCR crystal structures on structural modeling is discussed extensively as are critical insights from simulations in the second part of the book. The third part reports recent progress in rational ligand discovery and mathematical modeling, whereas the fourth part provides an overview of bioinformatics tools and resources that are available for GPCRs.

This book addresses the differentiation control of skeletal muscle in different locations of the vertebrate body Particular attention is paid to novel regulatory molecules and signals as well as the heterogeneity of origin that have revealed a developmental overlap between skeletal and cardiac muscle. Different functional muscle groups are the product of the evolution of the vertebrate classes, making a phylogenetic comparison worthwhile for understanding the role of muscle stem cells and precursors in myogenesis. New insights into the hierarchy of transcription factors, particularly in the context of these different muscle groups have been gained from detailed investigations of the spatio-temporal and regulatory relationships derived from mouse and zebrafish genetics and avian microsurgery. Importantly, epigenetic mechanisms that have surfaced recently, in particular the role of MyomiRs, are also surveyed. With an eye to the human patient, encouraging results have been generated that identify parallels between embryonic myogenesis and regenerating myofibers due to common regulatory molecules. On the other hand, both processes differ considerably in quality and complexity of the processes employed. Interestingly, the heterogeneity in embryonic sources from which skeletal muscle groups in the vertebrate including the human body take origin is paralleled by differences in their susceptibility to particular muscle dystrophies as well as by the characteristics of the satellite cells involved in regeneration. The progress that has been made in the field of muscle stem cell biology, with special focus on the satellite cells, is outlined in this book by experts in the field. The authors review recent insights of the heterogeneous nature of these satellite cells regarding their gene signatures and regeneration potential. Furthermore, an improved understanding of muscle stem cells seems only possible when we study the impact of the cell environment on efficient stem cell replacement therapies for muscular dystrophies, putting embryological findings from different vertebrate classes and stem cell approaches into context.

The main purpose of this volume is to provide a focused analysis of the function of the G protein-coupled signaling pathways that operate in the interconnected network of retinal neurons as they detect and encode the information carried by light. The organization of this volume will generally follow the path of signal flow in the retina. First we will describe recent advances in understanding the phototransduction cascade of rod and cone photoreceptors, which use signaling cascade based on the GPCR rhodopsin to transduce incident light into neural activity. Chapters will be devoted to unique specializations of the two major types of photosensitive cells that comprise the predominant input for our spatial and color vision. Subsequently, the mechanisms of synaptic information encoding by retinal ON bipolar cells will be described, where the GPCR mGluR6 plays a fundamental role. Chapters in this section will examine macromolecular organization of the mGluR6 signaling pathway as well as current understanding of its function. The functional characteristics of this signaling mechanism will be explored in detail. Additionally, this section will cover the role of dopamine receptors in modulating signal transmission between photoreceptors and ON-bipolar cells. Finally, chapters will be focused on the output neurons of the inner retina, ganglion cells, where the components of the emerging GPCR melanopsin cascade in intrinsically photosensitive ganglion cells will be detailed. Collectively these mechanisms allow the retina to represent visual space over a wide range of light intensities.

Protein expression in a heterologous host is a cornerstone of biomedical research and of the biotechnology industry. Despite the advanced state of protein expression technology improvements are still needed. For example, membrane proteins constitute a significant percentage of the total cellular proteins but as a class are very difficult to overexpress, especially in a heterologous host. The ideal host would have the ability to express any protein, with relevant post-translational modifications, and be as easy to work with as E. coli. In Heterologous Gene Expression in E. coli: Methods and Protocols, expert scientists intimately familiar with the relevant techniques offer chapters that greatly expand the utility of this expression host. The contributions in this detailed volume describe methods, for example, to successfully express proteins in E. coli that would otherwise form aggregates in this host, to add post-translational modifications, to incorporate non-standard amino acid residues or moieties into E. coli expressed proteins, to identify binding partners, and to express membrane proteins. Written in the highly successful Methods in Molecular Biology (TM) format, chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Practical and cutting-edge, Heterologous Gene Expression in E. coli: Methods and Protocols seeks to familiarize the researcher with the myriad of E. coli expression strains available and move E. coli closer to that ideal of the perfect host.
