ATP- and membrane-binding protein that probably controls membrane reorganization/tubulation upon ATP hydrolysis. Plays a role in early endosomal transport (PubMed:17233914, PubMed:18331452). During sprouting angiogenesis, in complex with PACSIN2 and MICALL1, forms recycling endosome-like tubular structure at asymmetric adherens junctions to control CDH5 trafficking (By similarity). {ECO:0000250|UniProtKB:Q9EQP2, ECO:0000269|PubMed:17233914, ECO:0000269|PubMed:18331452}. This is the function of ENSG00000103966 (EHD4, EH domain containing 4).
