**Background of Recombinant Human EHD3 Protein**
The Eps15 homology domain-containing protein 3 (EHD3) belongs to the EHD family of ATP-binding proteins involved in membrane trafficking and intracellular vesicle transport. EHD3 is primarily associated with recycling endosomes, where it regulates endocytic sorting, tubular vesicle formation, and cargo recycling to the plasma membrane or other organelles. It plays a critical role in maintaining cellular homeostasis by modulating endocytic pathways, particularly in specialized cells like cardiomyocytes and neurons.
Recombinant human EHD3 protein is engineered using expression systems (e.g., *E. coli* or mammalian cells) to produce a purified, functional form for research. Structurally, EHD3 contains an N-terminal EH domain for binding proteins with asparagine-proline-phenylalanine (NPF) motifs, a central ATP-binding domain, and a C-terminal coiled-coil region mediating oligomerization. These features enable its interaction with membrane lipids, cytoskeletal components, and trafficking machinery.
Studies link EHD3 dysfunction to cardiovascular diseases, neurodegenerative disorders, and cancer, highlighting its role in cellular signaling and organelle dynamics. Recombinant EHD3 is widely used in *in vitro* assays, structural studies, and drug discovery to explore trafficking mechanisms or validate therapeutic targets. Its production accelerates research into membrane biology and disease pathologies tied to vesicular transport defects.
