Recycling of endocytic cargoes utilizes multiple pathways employing Rab small GTPases.
Rab11a is associated with slow recycling pathways that are responsible for plasma membrane recycling in
non-polarized cells and the apical recycling system in polarized cells. Rab11a assembles multiple protein
complexes along the recycling pathway utilizing multiple Rab11-Family Interacting Proteins and Class V
myosins. Rab8a also assembles regulatory complexes associated with recycling pathways. While myosin V
species are involved in both Rab11a- and Rab8a-dependent pathways, the details of interactions between
these trafficking pathways remains unclear.
