Model | Experimentally Observed Cargo Behavior | ||
---|---|---|---|
End of run | Pause state | Rescue from pause | |
Tug-of-War | Stall due to stochastic motor detachment or attachment of opposing motor |
Both motors stalled in “a draw” (with potential cargo deformation). |
One motor wins, other motor detaches or backsteps (with potential recoil of cargo) |
Microtubule Tethering |
Motor switches to diffusive state |
Both motors bound in diffusive state |
Motor switches to moving state |
Mechanical Activation |
Motor switches into inactive state |
Either both detached or both bound and stalled |
Thermal or motor-driven mechanical activation |
Steric Disinhibition |
Motor switches into inhibited state |
Both detached, or one or both attached but inactive |
Release from inhibited state |
