Enables identical protein binding activity and protein domain specific binding activity. Involved in several processes, including plasma membrane tubulation; positive regulation of endocytic recycling; and positive regulation of myoblast fusion. Acts upstream of or within cortical actin cytoskeleton organization and endocytosis. Located in caveola; cytosol; and perinuclear region of cytoplasm. Is extrinsic component of membrane. Is expressed in aorta endothelium; blood vessel; brown fat; lymphatic vessel endothelium; and mesenteric artery. Orthologous to human EHD2 (EH domain containing 2).
