The actin cortex is an important part of the motile machinery of a eucaryotic cell. The cortex is steadily reorganized, for example, through the action of molecular motors forming active crosslinks between pairs of actin filaments. Here, the effect of correlations between molecular motors on the induced relative motion of two aligned filaments is investigated. It is found that the average relative velocity between filaments depends nonmonotonically on the motor concentration. Depending on the… CONTINUE READING
