The Eps15 homology (EH) domain-containing protein, EHD1, has recently been ascribed a role in the recycling of receptors internalized by clathrin-mediated endocytosis. A subset of plasma membrane proteins can undergo internalization by a clathrin-independent pathway regulated by the small GTP-binding protein ADP-ribosylation factor 6 (Arf6). Here, we report that endogenous EHD proteins, as well as transgenic tagged EHD1, are associated with long, membrane-bound tubules containing Arf6. EHD1 appears to induce tubule formation, which requires nucleotide cycling on Arf6 and intact microtubules. Mutations in the N-terminal P-loop domain or deletion of the C-terminal EH domain of EHD1 prevent association of EHD1 with tubules or induction of tubule formation. The EHD1 tubules contain internalized major histocompatibility complex class I (MHC-I) molecules that normally traffic through the Arf6 pathway. Recycling assays show that overexpression of EHD1 enhances MHC-I recycling. These observations suggest an additional function of EHD1 as a tubule-inducing factor in the Arf6 pathway for recycling of plasma membrane proteins internalized by clathrin-independent endocytosis.
