VPS29 (Vacuolar Protein Sorting 29) is a conserved component of the endosomal sorting complex required for transport (ESCRT) system, which plays a central role in membrane remodeling and cargo trafficking in eukaryotic cells. As part of the ESCRT-III subcomplex, VPS29 interacts with other ESCRT proteins like VPS26 and VPS35 to form the retromer complex, essential for retrograde transport of transmembrane receptors from endosomes to the trans-Golgi network. This process is critical for maintaining cellular homeostasis, receptor recycling, and lysosomal function. Structurally, VPS29 contains a phosphoesterase-like α/β-fold domain, enabling metal ion binding and protein-protein interactions.
Recombinant VPS29 protein is produced through heterologous expression systems (e.g., E. coli or mammalian cells) for functional studies. Its recombinant form allows researchers to investigate retromer assembly, endosomal sorting mechanisms, and membrane dynamics in vitro. Applications include studying ESCRT-mediated processes like viral budding, cytokinesis, and autophagy. Dysregulation of VPS29 is linked to neurodegenerative diseases (e.g., Alzheimer’s, Parkinson’s) due to impaired protein sorting and lysosomal dysfunction. Recombinant VPS29 is often tagged (e.g., His-tag) for purification and used in structural analyses (X-ray crystallography, NMR), interaction assays, or cellular rescue experiments in VPS29-deficient models. Current research focuses on its role in disease pathology and as a potential therapeutic target for membrane trafficking disorders.
