abstract：:Eps15 homology domain (EHD) proteins are conserved adenosine triphosphatases that are involved in membrane remodeling. EHD family members are structurally similar to the guanosine triphosphatase (GTPase) dynamin, and both are essential for the fission step of clathrin-mediated endocytosis.
