Energy and information flows in autonomous systems

J Ehrich, DA Sivak - Frontiers in Physics, 2023 - frontiersin.org
Multi-component molecular machines are ubiquitous in biology. We review recent progress
on describing their thermodynamic properties using autonomous bipartite Markovian …

Dynamic and thermodynamic bounds for collective motor-driven transport

MP Leighton, DA Sivak - Physical Review Letters, 2022 - APS
Molecular motors work collectively to transport cargo within cells, with anywhere from one to
several hundred motors towing a single cargo. For a broad class of collective-transport …

Performance scaling and trade-offs for collective motor-driven transport

MP Leighton, DA Sivak - New Journal of Physics, 2022 - iopscience.iop.org
Motor-driven intracellular transport of organelles, vesicles, and other molecular cargo is a
highly collective process. An individual cargo is often pulled by a team of transport motors …

Sliding of motor tails on cargo surface due to drift and diffusion affects their team arrangement and collective transport

S Yadav, A Kunwar - Physical Biology, 2022 - iopscience.iop.org
Kinesin is a microtubule-associated motor protein which works in teams to carry the cellular
cargo transport. Lipid rafts on membranous cargos reorganize, causing the motors present …

Cooperation and competition in the collective drive by motor proteins: mean active force, fluctuations, and self-load

C Karan, D Chaudhuri - Soft Matter, 2023 - pubs.rsc.org
We consider the dynamics of a bio-filament under the collective drive of motor proteins. They
are attached irreversibly to a substrate and undergo stochastic attachment–detachment with …

Bidirectional sliding of two parallel microtubules generated by multiple identical motors

J Allard, M Doumic, A Mogilner, D Oelz - Journal of mathematical biology, 2019 - Springer
It is often assumed in biophysical studies that when multiple identical molecular motors
interact with two parallel microtubules, the microtubules will be crosslinked and locked …

Stiffness of cargo–motor linkage tunes myosin VI motility and response to load

R Shrivastava, A Rai, M Salapaka… - Biochemistry, 2019 - ACS Publications
We examine the effect of cargo–motor linkage stiffness on the mechanobiological properties
of the molecular motor myosin VI. We use the programmability of DNA nanostructures to …

Stall force of a cargo driven by N interacting motor proteins

D Bhat, M Gopalakrishnan - Europhysics Letters, 2017 - iopscience.iop.org
We study a generic one-dimensional model for an intracellular cargo driven by N motor
proteins against an external applied force. The model includes motor-cargo and motor-motor …

Theoretical analysis of cargo transport by catch bonded motors in optical trapping assays

N Sundararajan, S Guha, S Muhuri, MK Mitra - Soft Matter, 2024 - pubs.rsc.org
Dynein motors exhibit catch bonding, where the unbinding rate of the motors from
microtubule filaments decreases with increasing opposing load. The implications of this …

the impact of Rate formulations on Stochastic Molecular Motor Dynamics

R Blackwell, D Jung, M Bukenberger, AS Smith - Scientific reports, 2019 - nature.com
Cells are complex structures which require considerable amounts of organization via
transport of large intracellular cargo. While passive diffusion is often sufficiently fast for the …
