Dynamic stability of spindles controlled by molecular motor kinetics
Otger Campas, Jaume Casademunt, Ignacio Pagonabarraga
We analyze the role of the force-dependent kinetics of motor proteins in the stability of antiparallel arrays of polar filaments, such as those in the mitotic spindle. We determine…

Collective dynamics of molecular motors pulling on fluid membranes
O. Campas, Y. Kafri, K. B. Zeldovich +2
The collective dynamics of weakly coupled processive molecular motors are considered theoretically. We show, using a discrete lattice model, that the velocity-force curves stro…

Chromosome Oscillations in Mitosis
Otger Campas, Pierre Sens
Successful cell division requires a tight regulation of chromosome motion via the activity of molecular motors. Many of the key players at the origin of the forces generating the m…
