Involved in endocytosis negative regulation, probably by influencing actin organization. Acts in early endocytic membrane fusion and membrane trafficking of recycling endosomes. Exhibits an inhibitory effect on endocytosis when over-expressed. GTP + H2O = GDP + H(+) + phosphate Homooligomer, and heterooligomer with EHD1 (PubMed:18547399). Interacts with AP-4 complex subunit sigma (At2g19790) (PubMed:19936242). The coiled coil domain (488-546) is required to inhibit endocytosis. Early flowering in short-day growth conditions. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. EHD subfamily.
