Displacement versus time against an optical trap for a PA-SSLB prepared from rat brain releasate. The SSLB initially shows dynein-driven (minus-directed) motion on a polarity-labeled MT. The SSLB is removed from the MT at the time point indicated and then placed back on the MT after a few seconds. This separation from the MT may allow rotational diffusion of the SSLB. Direction of motion reverses when the SSLB is placed back on the MT, presumably because a new area of the SSLB (now containing kinesin-1 motors) is now proximal to the MT.
