The interactions of cytoskeletal motors and filaments can be studied by gliding (or motility) assays,
in which the motors are immobilized on solid surfaces and act to pull the filaments along
As one increases the surface density of the filaments, these systems undergo
isotropic-nematic phase transitions
The nematic ordering is enhanced by increasing the
motor density because the motors lead to an effective lengthening of the filaments.
The transport of individual filaments by two species of motors, slow and fast ones, leads to different motility regimes with distinct transport patterns , in close analogy to the stochastic tug-of-war between two antagonistic teams of motors .
