Mature autophagosomes in the axon are transported by the microtubule motor dynein, activated by JNK-interacting proteins 3 and 4 (JIP3/4). This motility is regulated by the small GTPases ARF6 and RAB10. The tight regulation of autolysosomal transport is essential for intracellular recycling to maintain neuronal homeostasis.
