Book Synopsis Protein Homeostasis by : Richard I. Morimoto
Download or read book Protein Homeostasis written by Richard I. Morimoto and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper folding of proteins is crucial for cell function. Chaperones and enzymes that post-translationally modify newly synthesized proteins help ensure that proteins fold correctly, and the unfolded protein response functions as a homeostatic mechanism that removes misfolded proteins when cells are stressed. This book covers the entire spectrum of proteostasis in healthy cells and the diseases that result when control of protein production, protein folding, and protein degradation goes awry.

Book Synopsis Protein Homeostasis, Second Edition by : Richard I. Morimoto
Download or read book Protein Homeostasis, Second Edition written by Richard I. Morimoto and published by Perspectives Cshl. This book was released on 2019 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: The entire life cycle of a protein-from synthesis and folding to transport and degradation-is carefully controlled by the proteostasis network. This network, consisting of many interconnected pathways and processes, manages protein homeostasis by dynamically responding to the needs of the cell. Stress and aging can challenge the proteostasis network, resulting in the aggregation of misfolded proteins-a feature of numerous neurodegenerative conditions. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology provides a comprehensive update on how the proteostasis network functions in healthy cells and the diseases that result when protein quality control goes awry. The contributors examine the relevant biochemical attributes of proteins (e.g., solubility), the functions of normal protein aggregates (e.g., biofilm formation in bacteria), and the various heat shock proteins, chaperones, translocation machineries, proteasomes, signaling factors, and transcriptional programs involved in proteostasis. The roles of specific subcellular structures-the endoplasmic reticulum, mitochondria, ribosomes, lysosomes, and cytoplasm-in protein quality control are covered, as is the regulation of proteostasis at the organismal level (e.g., via neuronal activity). Discussions of the responses by cells when errors in protein quality control occur, the medical disorders that can result (e.g., Alzheimer disease), and pharmacologic approaches to ameliorate protein conformational disorders are also included. This book is therefore an essential reference for biochemists, cell biologists, and all biomedical scientists wishing to understand the pathological consequences of and potential therapies for proteostasis deficiencies in common human diseases.

The coverage mainly focuses on the basics of maintaining proteostasis, the consequences of proteostatic system failure, and how chaperone systems constantly maintain proteostasis. In addition, the book presents in detail different treatment strategies for diseases caused by proteostatic system failure, as well as the inhibition of proteostatic failure using small molecule compounds. It examines advances in the modulation of proteopathies, providing a comprehensive source of key mechanistic insights on these diseases. As such, the book offers a valuable resource for beginners and more experienced investigators alike who are looking for detailed and reliable information on protein homeostasis, the diseases that can develop due to related imbalances and the essential role of molecular and chemical chaperones.
Book Synopsis Plant Proteases by : Mercedes Diaz-Mendoza
Download or read book Plant Proteases written by Mercedes Diaz-Mendoza and published by Frontiers Media SA. This book was released on 2020-01-24 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant proteases are involved in most aspects of plant physiology and development, playing key roles in the generation of signaling molecules and as regulators of essential cellular processes such as cell division and metabolism. They take part in important pathways like protein turnover by the degradation of misfolded proteins and the ubiquitin-proteasome pathway, and they are responsible for post-translational modifications of proteins by proteolysis at highly specific sites. Proteases are also implicated in a great variety of environmentally controlled processes, including mobilization of storage proteins during seed germination, development of seedlings, senescence, programmed cell death and defense mechanisms against pests and pathogens. However, in spite of their importance, little is known about the functions and mode of actions of specific plant proteases. This Research Topic collects contributions covering diverse aspects of plant proteases research.
Book Synopsis The Discovery and Characterization of Small Molecule 20s Proteasome Activators by : Evert Njomen
Download or read book The Discovery and Characterization of Small Molecule 20s Proteasome Activators written by Evert Njomen and published by . This book was released on 2019 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintenance of proteome fidelity is required to preserve the health of an organism in defiance of developmental fluxes, environmental insults, infectious diseases, and the challenges of aging. This crucial role is the responsibility of the proteostasis (protein homeostasis) network, a multicomponent and unified system involving protein synthesis, folding, and degradation. The degradation system is regulated by the proteasome and the autophagy pathways. These proteolytic systems have thus emerged as therapeutic targets for numerous proteostasis disorders. However, their therapeutic regulation is only feasible if there is a fine understanding of how they function, and the mechanisms of crosstalk underlying their cooperative nature. After more than three decades since the discovery of the proteasome, there is still so much to be known about this exquisite enzyme. Proteolysis by the proteasome could be 20S- or 26S-mediated and may or may not be ubiquitin-dependent. The goal of this dissertation was to discover and characterize small molecules that allow for the decoding of 20S-mediated proteolysis and its role in the regulation of autophagy, with the hope of finding new vulnerabilities for proteostasis drug discovery.In this endeavor, two classes of 20S proteasome activators; imidazolines and phenothiazines were identified via high throughput screening (HTS). In a mechanistic study consisting of cellular, biochemical, biophysical and computational approaches, the imidazoline, TCH-165, was found to stabilize the open-gate active conformation of the human 20S proteasome. This translated into enhanced degradation of cancer-driving intrinsically disordered proteins (IDPs) such as c-Myc, and sensitization of both established and primary cancer cells to this molecule. TCH-165 was also found to enhance 20S-mediated clearance of two key SNARE proteins; SNAP29 and STX17, with subsequent inhibition of autolysosome formation. These observations implicate the 20S proteasome as a key regulator of autophagic flux. The clearance of ubiquitinylated proteins was not affected at concentrations required to boost 20S-mediated degradation of these IDPs. Thus, the 20S-ubiquitin-independent pathway could be enhanced without significantly affecting the 26S-ubiquitin-dependent pathway. These findings provide a new targetable vulnerability for IDP-driven cancers and autophagy-associated chemoresistance.In a proof-of-concept approach, the phenothiazine, chlorpromazine was modified to diminish its dopamine D2 receptor (D2R) activity while retaining its ability to enhance 20S-mediated proteolysis of IDPs associated with neurodegenerative disorders. Using these molecules as controls, the AlphaLISA technology was applied in a proteasome-protein degradation system thereby allowing for the development of an assay that allows for the measurement of 20S activation at the cellular and protein levels. These small molecule 20S agonists can therefore serve as leads to further explore the therapeutic potential of 20S activation in proteostasis disorders or as new tools to provide insight into the ambiguous mechanics of 20S-gate regulation and signaling.In an expanded exploration to cover infectious diseases, some imidazolines were found to inhibit the growth of Mycobacterium tuberculosis (Mtb), the causative agent for tuberculosis (TB). Given the structural differences between human and Mtb proteasome, CRISPRi/dCas9 system was used to validate the Mtb proteasome as a target for this anti-mycobacterium activity.
