Structural Polymorphism of the Cytoskeleton: A Model of Linker-Assisted Filament Aggregation
Itamar Borukhov, Robijn F. Bruinsma, William M. Gelbart +1
The phase behavior of charged rods in the presence of inter-rod linkers is studied theoretically as a model for the equilibrium behavior underlying the organization of actin filame…
Inter-filament Attractions Narrow the Length Distribution of Actin Filaments
David Biron, Elisha Moses, Itamar Borukhov +1
We show that the exponential length distribution that is typical of actin filaments under physiological conditions dramatically narrows in the presence of (i) crosslinker proteins…
Effect of Mono- and Multivalent Salts on Angle-dependent Attractions between Charged Rods
Kun-Chun Lee, Itamar Borukhov, William M. Gelbart +2
Using molecular dynamics simulations we examine the effective interactions between two like-charged rods as a function of angle and separation. In particular, we determine how the…
Raft Instability of Biopolymer Gels
I. Borukhov, R. F. Bruinsma
Following recent X-ray diffraction experiments by Wong, Li, and Safinya on biopolymer gels, we apply Onsager excluded volume theory to a nematic mixture of rigid rods and strong ``…
Elastically-Driven Linker Aggregation between Two Semi-Flexible Polyelectrolytes
I. Borukhov, R. F. Bruinsma, W. M. Gelbart +1
The behavior of mobile linkers connecting two semi-flexible charged polymers, such as polyvalent counterions connecting DNA or F-actin chains, is studied theoretically. The chain b…
Polyelectrolyte Titration: Theory and Experiment
I. Borukhov, D. Andelman, R. Borrega +3
Titration of methacrylic acid / ethyl-acrylate copolymers is studied experimentally and theoretically. At low salt concentrations, this polyacid exhibits a plateau in the titration…
