Myosin Vb Interacts with Rab8a on a Tubular Network Containing EHD1 and EHD3
Myosin Vb Interacts with Rab8a on a Tubular Network Containing EHD1 and EHD3
Cells use multiple pathways to internalize and recycle cell surface components. Although Rab11a and Myosin Vb are involved in the recycling of proteins internalized by clathrin-mediated endocytosis, Rab8a has been implicated in nonclathrin-dependent endocytosis and recycling. By yeast two-hybrid assays, we have now demonstrated that Myosin Vb can interact with Rab8a, but not Rab8b. We have confirmed the interaction of Myosin Vb with Rab11a and Rab8a in vivo by using fluorescent resonant energy transfer techniques. Rab8a and Myosin Vb colocalize to a tubular network containing EHD1 and EHD3, which does not contain Rab11a. Myosin Vb tail can cause the accumulation of both Rab11a and Rab8a in collapsed membrane cisternae, whereas dominant-negative Rab11-FIP2(129-512) selectively accumulates Rab11a but not Rab8a. Additionally, dynamic live cell imaging demonstrates distinct pathways for Rab11a and Rab8a vesicle trafficking. These findings indicate that Rab8a and Rab11a define different recycling pathways that both use Myosin Vb.
