**Background of Recombinant Human ZFYVE1 Protein**
ZFYVE1 (Zinc Finger FYVE-Type Containing 1), also known as protrudin, is a multifunctional protein encoded by the *ZFYVE1* gene in humans. It is characterized by an N-terminal FYVE domain, which binds phosphatidylinositol 3-phosphate (PI3P) in membrane bilayers, and a C-terminal region involved in protein-protein interactions. ZFYVE1 plays a critical role in regulating intracellular membrane trafficking, particularly in the endoplasmic reticulum (ER), where it facilitates vesicle formation and cargo transport. Notably, it promotes the extension of neurites in neuronal cells and participates in autophagy-lysosome pathways, impacting cellular homeostasis.
The protein is implicated in lipid metabolism, membrane dynamics, and organelle crosstalk. It interacts with key regulators like Rab11 and SNARE proteins to mediate vesicular transport and membrane fusion. Dysregulation of ZFYVE1 has been linked to neurodegenerative disorders, such as hereditary spastic paraplegia, due to its role in maintaining ER structure and function. Additionally, altered ZFYVE1 expression is observed in certain cancers, suggesting potential involvement in tumor progression.
Recombinant human ZFYVE1 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains functional domains and is widely used to study its biochemical properties, interactome, and therapeutic potential. Its applications span *in vitro* assays, structural studies, and drug screening for diseases associated with membrane trafficking defects.
