Entropic forces drive contraction of cytoskeletal networks

M Braun, Z Lansky, F Hilitski, Z Dogic, S Diez - BioEssays, 2016 - Wiley Online Library
The cytoskeleton is a network of interconnected protein filaments, which provide a three‐
dimensional scaffold for cells. Remodeling of the cytoskeleton is important for key cellular …

Stochastic ratcheting on a funneled energy landscape is necessary for highly efficient contractility of actomyosin force dipoles

JE Komianos, GA Papoian - Physical Review X, 2018 - APS
Current understanding of how contractility emerges in disordered actomyosin networks of
nonmuscle cells is still largely based on the intuition derived from earlier works on muscle …

Pivoting of microtubules driven by minus-end-directed motors leads to spindle assembly

L Winters, I Ban, M Prelogović, I Kalinina, N Pavin… - BMC biology, 2019 - Springer
Background At the beginning of mitosis, the cell forms a spindle made of microtubules and
associated proteins to segregate chromosomes. An important part of spindle architecture is …

Theory of antiparallel microtubule overlap stabilization by motors and diffusible crosslinkers

M Lera‐Ramirez, FJ Nédélec - Cytoskeleton, 2019 - Wiley Online Library
Antiparallel microtubule bundles are essential structural elements of many cytoskeletal
structures, for instance, the mitotic spindle. Sliding of microtubules relative to each other can …

Mechanisms of Chromosome Positioning During Mitosis

I Sigmund, D Božan, I Šarić, N Pavin - PRX Life, 2024 - APS

Embedding dual function into molecular motors through collective motion

N Saito, K Kaneko - Scientific reports, 2017 - nature.com
Protein motors, such as kinesins and dyneins, bind to a microtubule and travel along it in a
specific direction. Previously, it was thought that the directionality for a given motor was …
