Book Synopsis Investigation of ER-Golgi Membrane Proteins Influencing COPII Tethering and Fusion by : Indrani Mukherjee
Download or read book Investigation of ER-Golgi Membrane Proteins Influencing COPII Tethering and Fusion written by Indrani Mukherjee and published by . This book was released on 2016 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein secretion is executed by the secretory pathway, which involves the delivery of membrane and soluble secretory proteins in vesicle intermediates that capture newly-synthesized proteins assembled in the endoplasmic reticulum (ER) and then transport captured cargo to the Golgi apparatus. This fundamental pathway is conserved across all eukaryotes. Genetic, biochemical and structural studies have provided a framework for distinct steps of protein trafficking between the ER and the Golgi in yeast and mammalian cells. Recent studies have also uncovered a novel role for calcium during vesicle budding in the early secretory pathway. Despite the wealth of knowledge available about the early secretory pathway, fundamental questions remain regarding how ER-Golgi associated proteins function in tethering and fusion of ER-derived vesicles with the Golgi apparatus. A proteomic analysis of COPII vesicles identified the ER-Golgi associated proteins Sly41 and Coy1, which influence trafficking in the early secretory pathway but are of unknown function. This thesis investigates the role of Sly41 and Coy1 in ER-Golgi transport. The multispanning membrane protein Sly41 was initially identified as a multicopy suppressor of loss of function mutations in YPT1 and USO1, which are essential for tethering of COPII vesicles to Golgi membranes. Our characterization revealed that Sly41 is packaged into COPII vesicles, cycles between the ER-Golgi compartments, and trafficking of Sly41 between early secretory compartments is required for its suppressive activity. A novel genetic interaction between SLY41 and the Golgi-localized Ca2+/Mn2+ pump encoded by PMR1 indicated a role for Sly41 in cellular calcium homeostasis. In vivo analysis revealed that overexpression of Sly41 produced higher levels of intracellular calcium in yeast cells. In vitro cysteine-disulfide crosslinking assays were used to monitor SNARE-mediated fusion of COPII vesicles with Golgi membranes and indicated that calcium can stimulate membrane fusion in the absence of maximal tethering. Together, these findings provide evidence for a regulatory role for calcium in membrane fusion at the Golgi complex and explain how Sly41 overexpression can suppress deficiencies in COPII vesicle tethering. C̲ASP o̲f y̲east, termed Coy1, was initially identified based on sequence homology to Golgi-localized CASP in mammalian cells. The extended coiled-coil structure encoded by COY1 in addition to genetic interactions with other early secretory pathway genes such as SNARE protein encoding SEC22 and GOS1, suggested a role for COY1 in vesicle tethering. This hypothesis was supported by a novel genetic interaction identified between COY1 and GRH1, which encodes the Grh1 protein known to influence vesicle tethering at the Golgi. Out characterization of Coy1 revealed that the protein is efficiently packaged into COPII vesicles and overexpression of Coy1 led to deleterious effects on in vitro transport and COPII vesicle tethering. Taken together, the data suggest that the Golgi-membrane protein Coy1 influences COPII vesicle tethering at the Golgi.

This book was released on 2012-11-19 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Main Question: G protein coupled receptors are involved in highly efficient and specific activation of signalling pathways. How do GPCR signalling complexes get assembled to generate such specificity? In order to answer this question, we need to understand how receptors and their signalling partners are synthesized, folded and quality-controlled in order to generate functional proteins. Then, we need to understand how each partner of the signalling complex is selected to join a complex, and what makes this assembly possible. GPCRs are known to be able to function as oligomers, what drives the assembly into oligomers and what will be the effects of such organization on specificity and efficacy of signal transduction. Once the receptor complexes are assembled, they need to reach different locations in the cell; what drives and controls the trafficking of GPCR signalling complexes. Finally, defects in synthesis, maturation or trafficking can alter functionality of GPCRs signalling complexes; how can we manipulate the system to make it function normally again? Pharmacological chaperones may just be part of the answer to this question.

Book Synopsis Intracellular Signaling Mediators in the Circulatory and Ventilatory Systems by : Marc Thiriet
Download or read book Intracellular Signaling Mediators in the Circulatory and Ventilatory Systems written by Marc Thiriet and published by Springer Science & Business Media. This book was released on 2012-09-26 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volumes in this authoritative series present a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to phenomenological models of nano- and microscopic events in a corrector scheme of regulated mechanisms when the vessel lumen caliber varies markedly. Therefore, investigation of flows of blood and air in physiological conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning. Volume 4 is devoted to major sets of intracellular mediators that transmit signals upon stimulation of cell-surface receptors. Activation of signaling effectors triggers the release of substances stored in cellular organelles and/or gene transcription and protein synthesis. Complex stages of cell signaling can be studied using proper mathematical models, once the role of each component is carefully handled. Volume 4 also reviews various categories of cytosolic and/or nuclear mediators and illustrates some major signal transduction pathways, such as NFkappaB axis, oxygen sensing, and mechanotransduction.
Book Synopsis Endocytosis in Plants by : Jozef Šamaj
Download or read book Endocytosis in Plants written by Jozef Šamaj and published by Springer Science & Business Media. This book was released on 2012-10-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocytosis is a fundamental cellular process by means of which cells internalize extracellular and plasma membrane cargos for recycling or degradation. It is important for the establishment and maintenance of cell polarity, subcellular signaling and uptake of nutrients into specialized cells, but also for plant cell interactions with pathogenic and symbiotic microbes. Endocytosis starts by vesicle formation at the plasma membrane and progresses through early and late endosomal compartments. In these endosomes cargo is sorted and it is either recycled back to the plasma membrane, or degraded in the lytic vacuole. This book presents an overview of our current knowledge of endocytosis in plants with a main focus on the key molecules undergoing and regulating endocytosis. It also provides up to date methodological approaches as well as principles of protein, structural lipid, sugar and microbe internalization in plant cells. The individual chapters describe clathrin-mediated and fluid-phase endocytosis, as well as flotillin-mediated endocytosis and internalization of microbes. The book was written for a broad spectrum of readers including students, teachers and researchers.

Book Synopsis Sexual Reproduction in Animals and Plants by : Hitoshi Sawada
Download or read book Sexual Reproduction in Animals and Plants written by Hitoshi Sawada and published by Springer. This book was released on 2014-02-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Book Synopsis The Golgi Apparatus and Centriole by : Malgorzata Kloc
Download or read book The Golgi Apparatus and Centriole written by Malgorzata Kloc and published by Springer. This book was released on 2020-09-04 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume takes a closer look how the cell organelles Golgi apparatus (also known as the Golgi complex or Golgi body), and centriole are structurally and functionally intertwined. Initially, it was believed that the role of Golgi complex is limited to the packaging and preparation for secretion of various cellular proteins, while the centriole participates in cell division and cilia formation. However, since their discovery nearly 200 years ago, it became clear that these two organelles are interacting, and that their functions are much more complex and far reaching than previously thought. Recent findings indicate that the Golgi–Centriole relationship may be important for directional protein transport, cell polarization and cell cycle progression. Current studies indicate that Golgi and centriole also participate in development and act as cellular and immunological sensors, and that their abnormalities lead to cell and developmental abnormalities, Alzheimer, cancer, various lipid disorders and neurological and immunological diseases in humans. This volume combines the latest information on the structure, molecular composition, and roles of Golgi and centriole in various cellular functions and diseases. The better understanding of the Golgi–centriole interactions may lead to the development of novel therapies for the treatment of various diseases, including cancer.
