**Recombinant Human VPS41 Protein: Background**
VPS41 (Vacuolar Protein Sorting 41) is a critical component of the HOPS (Homotypic Fusion and Vacuole Protein Sorting) complex, which regulates endosome-lysosome fusion, autophagosome maturation, and vesicular trafficking in eukaryotic cells. As a member of the Sec1/Munc18 protein family, VPS41 facilitates membrane tethering and fusion by interacting with RAB7A, STX17. and other partners, ensuring proper lysosomal degradation and organelle homeostasis. Structurally, VPS41 contains conserved CLATHRIN and DYSM domains, essential for its role in membrane dynamics.
Dysregulation of VPS41 is linked to neurological disorders (e.g., Parkinson’s disease) and rare conditions like Chediak-Higashi syndrome, where mutations impair lysosomal function and melanosome biogenesis. Recombinant human VPS41 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains functional domains and post-translational modifications, enabling studies on its structure, interaction networks, and pathological mechanisms.
Applications include *in vitro* reconstitution of membrane fusion, drug screening for lysosomal disorders, and gene therapy research. Its recombinant form often incorporates tags (e.g., His-tag) for purification and detection, ensuring utility in biochemical assays and therapeutic development. Research on VPS41 highlights its dual role in cellular quality control and disease, making it a target for precision medicine in neurodegeneration and lysosomal storage disorders.
