Before revision:  However, unlike other ligands, the length of a MT can change with time because of its polymerization-depolymerization kinetics . The simple model developed here is motivated by the MTs linked to the cell cortex by dynein motors .
After revision:  However, unlike other ligands, the length of a MT can change with time because of its polymerization-depolymerization kinetics , while multiple motor receptors tend to walk actively along the MT length. These processes, combined with force-mediated unbinding of the motors, result in an elaborate behavior of the MT connection to the cell cortex by dynein motors .
