Download or read book Endocytosis and Signaling written by Christophe Lamaze and published by Springer. This book was released on 2018-08-10 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the context dependency of cell signaling by showing how the endosomal system helps to structure and regulate signaling pathways. The location and concentration of signaling nodes regulate their activation cycles and engagement with distinct effector pathways. Whilst many cell signaling pathways are initiated from the cell surface, endocytosis provides an opportunity for modulating signaling networks’ output. In this book, first a series of reviews describe the endocytic and endosomal system and show how these subcellular platforms sort and regulate a wide range of signaling pathway components and phenotypic outputs. The book then reviews the latest scientific insights into how endocytic trafficking and subcellular location modulate a set of major pathways that are essential to normal cellular function and organisms’ development.

Download or read book The Ins and Outs of Protein Trafficking Pathways written by Hirendrasinh Bhupatsinh Parmar and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorting and trafficking of integral membrane proteins to the plasma membrane is essential for cellular homeostasis. Our understanding of the pathways and sorting signals that regulate protein trafficking is far from complete, particularly as it relates to protein exit from the Golgi. The reovirus fusion-associated small transmembrane (FAST) proteins are small integral membrane proteins that traffic through the ER-Golgi pathway to the plasma membrane where they cause cell-cell membrane fusion. The small sizes of FAST proteins and their simple structures provide an excellent system to identify factors and pathways affecting plasma membrane trafficking. Using the reptilian reovirus p14 FAST protein, I discovered that a polybasic motif (PBM), located four residues downstream of the transmembrane domain in the cytoplasmic tail of p14, is required for p14 export from the Golgi to the plasma membrane. Extensive mutagenesis of the PBM indicated that the number, but not the identity or position, of basic residues in the PBM directs p14 trafficking to the plasma membrane, with a minimum of three basic residues being required for efficient Golgi export. Insertion of the PBM into a Golgi-resident ERGIC-53 chimeric protein resulted in protein trafficking to the plasma membrane, indicating the p14 PBM functions as an autonomous Golgi export signal. I also discovered that the PBM can serve diverse trafficking roles depending on its proximity to the transmembrane domain. The PBM exerts no effect when located at internal positions in the 68-residue p14 cytoplasmic tail, it functions as an ER retention signal when located at the C-terminus, and when present at both membrane-proximal and -distal locations promotes export to and retrieval from the Golgi complex. Interestingly, the conflicting signals provided by membrane-proximal and -distal PBMs induce extensive ER tubulation and segregation of luminal ER components. A single trafficking motif can therefore exert remarkably diverse, position-dependent effects on protein trafficking and membrane compartment morphogenesis. To determine how the p14 PBM directs Golgi-plasma membrane transport, I examined the effects of various trafficking factors and pathways on this process. Yeast two-hybrid analysis identified Rab11A as a genetic interaction partner of p14. Co-immunoprecipitation (co-IP) determined that p14 interacts preferentially with GTP-bound activated Rab11A in a PBM-dependent manner. Overexpression of dominant-negative Rab11A, but not Rab5, significantly reduced p14 surface expression. Fluorescence resonance energy transfer (FRET) microscopy indicated activated Rab11 directly interacts with p14 dependent on the PBM, the first example of activated Rab11 directly interacting with membrane cargo for Golgi-plasma membrane trafficking. Furthermore, RNA interference revealed that both Rab11 and adaptor protein 1 (AP1), but not AP3 or AP4, are required for efficient p14 trafficking from the trans-Golgi network (TGN) to the plasma membrane. This is also the first indication of Rabs regulating adaptor proteins at the TGN for anterograde vesicle traffic, and provides a clear indication that AP1 can mediate anterograde traffic from the Golgi to the plasma membrane. I conclude that the p14 PBM functions as a novel autonomous tribasic Golgi export signal by directing interaction with activated Rab11, resulting in p14 sorting into AP1-coated vesicles at the TGN for trafficking to the plasma membrane, either directly or via endosomal recycling pathways.
Download or read book Membrane Sorting in the Endocytic Pathway written by Valentina Mercanti and published by . This book was released on 2007 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: During my thesis work I studied membrane sorting in the endocytic pathway, in mammalian cells and in the amoeba "Dictyostelium discoideum". In the first part (1), I studied sorting of membrane proteins devoid of known endocytosis signals. My results show that, in addition to cytoplasmic tails of membrane proteins, then transmembrane regions determine whether they are excluded or not from clathrincoated pits, and thus controls their access to endosomal compartmemts. In the second part (2), I studied membrane sorting during phagocytosis and macropinocytosis. I used for this the amoeba "Dictyostelium discoideum". My results show that several plasma membrane proteins are excluded from the membrane of the newly formed phagosome. This exclusion starts in the membrane delimiting the phagocytic and the macropinocytic cups. Analysis of mutant strains revealed that clathrin-associated adaptor complexes were not necessary for this selective exclusion. In third part (3), I characterized the previously uncharacterized recycling endosomes in "Dictyostelium discoideum"
Download or read book Protein Trafficking in Plant Cells written by J. Soll and published by Springer Science & Business Media. This book was released on 1998-08-31 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The highly structured eucaryotic cell with its complex division of biochemical labour requires a distinct protein complement in each cellular structure and compartment. Nuclear coded and cytosolically synthesized polypeptides are specifically sorted to every corner of the cell in a post- or co-translational manner. The presence of separate genomes and protein translation machineries in plastids and mitochondria requires further coordination not only on the transcriptional, translational but also most likely on the protein import level. Numerous different protein transport systems have developed and coexist within plant cells to ensure the specific and selective composition of every sub-cellular compartment. This volume summarizes the current knowledge on protein trafficking in plant cells. Aside from the fundamental aspects in cell biology of how specific pre-protein sorting and translocation across biological membranes is achieved, a major focus is on transport, modification and deposition of plant storage proteins. The increasing use of plants as bioreactors to provide custom-designed proteins of different usage requires detailed understanding of these events. This text is directed not only at students and professionals in plant cell and molecular biology but also at those involved in horticulture and plant breeding. It is intended to serve as a text and guide for graduate-level courses on plant cell biology and as a valuable supplement to courses in plant physiology and development. Scientists in other disciplines who wish to learn more about protein translocation in plants will also find this text an up-to-date source of information and reference.
