Data for: Topological defects produce kinks in biopolymer filament bundles

Qingda Hu, Maximilian Grill, Elliot Botvinick, Wolfgang Wall, Valentin Slepukhin & Alex Levine
Bundles of stiff filaments are ubiquitous in the living world, found both in the cytoskeleton and in the extracellular medium. These bundles are typically held together by smaller cross-linking molecules. We demonstrate, analytically, numerically, and experimentally, that such bundles can be kinked, that is, have localized regions of high curvature that are long-lived metastable states. We propose three possible mechanisms of kink stabilization: a difference in trapped length of the filament segments between two cross-links,...
