This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.

The ubiquitin-proteasome pathway consists of ubiquitin, substrate proteins, E1 enzymes, E2 enzymes, E3 enzymes, and proteasome, which acts in a series of enzymatic reaction chains to ubiquitinate substrate proteins such as surplus and misfolded proteins for degradation by the proteasome to maintain the balance between protein synthesis and degradation in a cell and tissue. Moreover, deubiquitinating enzymes can remove the attached ubiquitin chain, which results in a reverse ubiquitination-deubiquitination process involved in multiple biological processes in a cell and tissue. The changes of components in the ubiquitin-proteasome pathway are associated with multiple pathophysiological processes, such as cancers and neurodegenerative diseases. This book presents the new advances in concepts, analytical methodology, and application of ubiquitin-proteasome pathway for clarification of molecular mechanisms and discovery of new therapeutic targets and drugs in different diseases.

In Single Molecule Studies of Proteins, expert researchers discuss the successful application of single-molecule techniques to a wide range of biological events, such as the imaging and mapping of cell surface receptors, the analysis of the unfolding and folding pathways of single proteins, the analysis interaction forces between biomolecules, the study of enzyme catalysis or the visualization of molecular motors in action. The chapters are aimed at established investigators and post-doctoral researchers in the life sciences wanting to pursue research in the various areas in which single-molecule approaches are important; this volume also remains accessible to advanced graduate students seeking similar research goals.

This volume details novel and popular approaches to decipher the Ubiquitin Code. Chapters guide readers through ubiquitin chain complexity, methods to generate non-hydrolysable ubiquitin-NEDD8, a fully synthetic method for the linear synthesis of fluorescently labelled rhodamine LC3A and LC3B, a HECT ligase-mediated ubiquitylation in vitro, a RNAi-based screening to identify DUBs, a Yuh1 activity assay, a pull-down to isolate K48 and K63 chains using specific nanobodies, identification of NeDDylated protein based in a NEDD8R74K mutant, in vivo identification of NEDDylated proteins from liver diseases, UbL-ID method to identify ubiquitin-like modified proteins, a LC3/GABARAP capturing system, and methods to isolate peptides that are closely associated with proteasomes or trapped inside the core particle of proteasomes in eukaryotic cells, among others. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls.
