Dynein will initiate translocation of late endosomes to microtubule minus ends only after interacting with betaIII spectrin, which requires the activities of Rab7-RILP and ORP1L..     ///    "Finally, the specific dynein motor receptor Rab7-RILP is transferred by ORP1L to betaIII spectrin. "    ///    "Still, p150(Glued) recruitment by Rab7-RILP does not suffice to induce dynein-driven minus-end transport of LEs. "
