Available in PDF, EPUB and Kindle. Book excerpt: Processive molecular motors are the proteins that transport various kinds of cargos within a cell. All processive motors have two motor domains that let the protein proceed by taking steps. These motor proteins can carry their cargos for microns by taking hundreds of steps before detaching form the cytoskeletal tracks they walk on. In year 2003 it has been reported that the position of a single fluorescent dye attached to a molecular motor can be located within ∼ 1 nm (with half-a-second temporal resolution) in vitro. This new localization technique is named Fluorescence Imaging with One Nanometer Accuracy (FIONA). Yildiz et al. has shown that FIONA is precise enough to resolve the hand-over-hand steps of the processive molecular motors myosin V, kinesin and myosin VI, in the order. In our study we have searched for the possibilities of working on the same motor proteins in vivo, in other words, inside live cells. In order to overcome the complications of imaging in live organisms we have tracked the cargos (organelles carried by motors) instead of single molecule markers bound to the motors. Fluorescently labeled peroxisomes and dark pigment carrying melanosomes can be tracked in vivo with high spatial (∼1.5 nm) and temporal (∼1 msec) resolution by the derivatives of FIONA. This has enabled us to resolve the stepwise motion of motor proteins conventional kinesin, cytoplasmic dynein, kinesin II and myosin V.

Book excerpt: Recent advances in molecular and biophysical techniques, particularly fluorescence and live cell imaging, are revolutionizing the study of cell motility. New bioprobes not only reveal simple intracellular localization, but also contain details of post-translational modifications, conformational state and protein-protein interactions. Coupling these insights with complementary advances in genetic and biochemical methods is enabling scientists to understand the processes involved in cell motility - from molecular motors to cell movements in vivo in a range of organisms and cell types. This book features landmark essays that provide an up to date and fascinating account of current research and concepts in cell motility.These cover the roles of molecular motors that drive movement and their interactions with the cytoskeleton as well as membrane dynamics that allow cells to change shape and to move. Cell motility plays a key role in development - there are chapters on the genetics of cell migration, the regulation of contact repulsion in growth cones, and the progression from cell migration to cell-cell adhesion. Cell motility is directional - experts describe the molecules that regulate chemotaxis, allowing cells to migrate along pathways specified by chemical gradients. Finally, cell motility can be perturbed by mutation--metastasis occurs when cells lose their normal intercellular interactions and invade other tissue types. All these processes are regulated by signals from the environment, including other tissues in the body, and the various molecules that transmit and transduce these signals are discussed. This book is a 'must read' for cell biologists working in a variety of fields, from development to wound healing, at all levels - post-doctoral fellows, post-graduate students and lab technicians. It is also stimulating reading for molecular and developmental biologists, biophysicists and biochemists.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Many cellular processes are driven by the collective action of motors working in teams. One such example of this type of phenomenon is intracellular transport -- the transport of cargoes carried out by teams of similar or opposite polarity motors (kinesin and dynein). In most cells, long-range transport occurs along microtubules that are oriented with their plus ends towards the cell periphery, and minus ends towards the cell body. Despite the presence of opposite polarity motors, the mechanism by which cargoes are directed to specific locations in the cell is not well understood. A set of microtubule-associated proteins (MAPs) and scaffolding molecules have been shown to have some effect on motility and cargo directionality, but the mechanism by which these molecules tune motor specific processivity is not well understood. Defects in intracellular trafficking can result in severe developmental and neurodegenerative diseases. One prominent example is Huntington’s disease (HD), which is an autosomal dominant neurodegenerative disorder caused by an extension of the CAG repeat region in the N-terminus of the huntingtin gene. Though it is clear that wild-type huntingtin plays a role in intracellular trafficking by interacting with motor and motor-associated proteins, it is unclear how post-translational modifications (PTMs) modulate the activity of motor proteins and the specific biophysical mechanism behind this activity. In HD, mutated huntingtin aggregates in neurons, disrupting cargo transport. Disruption in vesicle transport results in abnormal cell signaling and impaired clearance of damaged proteins and organelles. This suggests a mechanism where defects in transport are due to misregulation of motor protein activity by vesicle-bound huntingtin.In addition to scaffolding molecules like huntingtin, transport is also regulated by microtubule-associated proteins (MAPs) that bind along the microtubule surface. Tau is a neuronal MAP that stabilizes axonal microtubules by crosslinking them into bundles. It also indirectly modulates cargo motility by serving as a roadblock to motors. Misregulation of tau leads to a range of neurodegenerative diseases known as tauopathies, including Alzheimer’s disease (AD). In AD, tau hyperphosphorylation leads to the development of fibrillary bodies that aggregate to form neurofibrillary tangles (NFTs). Varying concentration of tau inhibits single motor and multiple motor activity. Yet, despite the presence of tau in healthy neurons, teams of motors are still able to navigate efficiently over long distances in the axon without being inhibited. Similar to tau, MAP7 (ensconsin) also binds along microtubules and stabilizes them. It organizes the microtubule cytoskeleton in mitosis and neuronal branching. MAP7 not only promotes the interaction of kinesin-1 to microtubules but also competes with tau for binding along microtubules to regulate kinesin transport. Since bidirectional motility is a hallmark of intracellular transport, understanding how MAPs regulate teams of kinesin and dynein motors will provide insight into how transport is regulated"--

Available in PDF, EPUB and Kindle. Book excerpt: Molecular motors convert chemical energy (typically from ATP hydrolysis) to directed motion and mechanical work. Biomolecular motors are proteins able of converting chemical energy into mechanical motion and force. Because of their dimension, the many small parts that make up molecular motors must operate at energies only a few times greater than those of the thermal baths. The description of molecular motors must be stochastic in nature. Their actions are often described in terms of Brownian Ratchets mechanisms. In order to describe the principles used in their movement, we need to use the tools that theoretical physics give us. In this book we centralize on the some physical mechanisms of molecular motors.

Book excerpt: Life is an enduring mystery. Yet, science tells us that living beings are merely sophisticated structures of lifeless molecules. If this view is correct, where do the seemingly purposeful motions of cells and organisms originate? In Life's Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. Below the calm, ordered exterior of a living organism lies microscopic chaos, or what Hoffmann calls the molecular storm -- specialized molecules immersed in a whirlwind of colliding water molecules. Our cells are filled with molecular machines, which, like tiny ratchets, transform random motion into ordered activity, and create the "purpose" that is the hallmark of life. Tiny electrical motors turn electrical voltage into motion, nanoscale factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city -- an unfathomable, complex collection of molecular workers working together to create something greater than themselves. Life, Hoffman argues, emerges from the random motions of atoms filtered through these sophisticated structures of our evolved machinery. We are agglomerations of interacting nanoscale machines more amazing than anything in science fiction. Rather than relying on some mysterious "life force" to drive them -- as people believed for centuries -- life's ratchets harness instead the second law of thermodynamics and the disorder of the molecular storm. Grounded in Hoffmann's own cutting-edge research, Life's Ratchet reveals the incredible findings of modern nanotechnology to tell the story of how the noisy world of atoms gives rise to life itself.

Book excerpt: Molecular motors' shuttling of cargo along cytoskeletal filaments is essential for many cellular processes. Motors are mechanoenzymes, and their response to external forces can influence their function. These responses have been largely mapped in dilute in vitro media. The cytosol, however, is crowded with a high concentration of macromolecules which can alter protein conformation, binding rates, reaction kinetics, and, therefore, motor function. Using live cell imaging and single-molecule optical trap measurements, the consequences of macromolecular crowding on cargo transport by kinesin-1 motors is investigated. Surprisingly, it is found that crowding significantly slows transport by teams of motors, while having no effect on single motor velocity. This emergent property of kinesin teams results from the individuals' increased sensitivity to hindering load in a crowded medium. To better understand how individual motor properties lead to emergent properties of kinesin teams, transport by multiple motor teams and their responses to force was simulated in silico. These simulations give results that are similar to those found in the in vitro experiments. Together, these results explain the long observed variability of cargo velocity in living cells, and suggest the use of crowding as a control parameter to study kinesin's mechanochemical cycle

It is only in the last few decades that technological breakthroughs in sensitive fluorescence microscopy and single-molecule manipulation techniques have made it possible to observe and manipulate single biomolecules and measure their individual properties. The methodologies presented in Single Molecule Techniques: Methods and Protocols are being applied more and more to the study of biologically relevant molecules, such as DNA, DNA-binding proteins, and motor proteins, and are becoming commonplace in molecular biophysics, biochemistry, and molecular and cell biology. The aim of Single Molecule Techniques: Methods and Protocols is to provide a broad overview of single-molecule approaches applied to biomolecules on the basis of clear and concise protocols, including a solid introduction to the most widely used single-molecule techniques, such as optical tweezers, single-molecule fluorescence tools, atomic force microscopy, magnetic tweezers, and tethered particle motion. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Single Molecule Techniques: Methods and Protocols serves as an ideal guide to scientists of all backgrounds and provides a broad and thorough overview of the exciting and still-emerging field of single-molecule biology.

Available in PDF, EPUB and Kindle. Book excerpt: This book develops the theory of continuous and discrete stochastic processes within the context of cell biology. In the second edition the material has been significantly expanded, particularly within the context of nonequilibrium and self-organizing systems. Given the amount of additional material, the book has been divided into two volumes, with volume I mainly covering molecular processes and volume II focusing on cellular processes. A wide range of biological topics are covered in the new edition, including stochastic ion channels and excitable systems, molecular motors, stochastic gene networks, genetic switches and oscillators, epigenetics, normal and anomalous diffusion in complex cellular environments, stochastically-gated diffusion, active intracellular transport, signal transduction, cell sensing, bacterial chemotaxis, intracellular pattern formation, cell polarization, cell mechanics, biological polymers and membranes, nuclear structure and dynamics, biological condensates, molecular aggregation and nucleation, cellular length control, cell mitosis, cell motility, cell adhesion, cytoneme-based morphogenesis, bacterial growth, and quorum sensing. The book also provides a pedagogical introduction to the theory of stochastic and nonequilibrium processes – Fokker Planck equations, stochastic differential equations, stochastic calculus, master equations and jump Markov processes, birth-death processes, Poisson processes, first passage time problems, stochastic hybrid systems, queuing and renewal theory, narrow capture and escape, extreme statistics, search processes and stochastic resetting, exclusion processes, WKB methods, large deviation theory, path integrals, martingales and branching processes, numerical methods, linear response theory, phase separation, fluctuation-dissipation theorems, age-structured models, and statistical field theory. This text is primarily aimed at graduate students and researchers working in mathematical biology, statistical and biological physicists, and applied mathematicians interested in stochastic modeling. Applied probabilists should also find it of interest. It provides significant background material in applied mathematics and statistical physics, and introduces concepts in stochastic and nonequilibrium processes via motivating biological applications. The book is highly illustrated and contains a large number of examples and exercises that further develop the models and ideas in the body of the text. It is based on a course that the author has taught at the University of Utah for many years.
