**Background of PLEKHF2 Recombinant Protein**
PLEKHF2 (Pleckstrin Homology and FYVE Domain-Containing Protein 2) is a member of the Plekstrin homology (PH) domain-containing protein family, which plays critical roles in membrane dynamics, intracellular signaling, and vesicular trafficking. The protein is characterized by its unique structural composition: an N-terminal PH domain, which binds phosphoinositides to facilitate membrane association, and a C-terminal FYVE domain, which specifically interacts with phosphatidylinositol 3-phosphate (PI3P) enriched in endosomal membranes. These domains enable PLEKHF2 to act as a scaffold or adaptor protein, coordinating interactions between membranes, cytoskeletal components, and signaling molecules.
Functionally, PLEKHF2 is implicated in endocytic trafficking, autophagy, and lysosomal biogenesis. Studies suggest its involvement in regulating endosome-lysosome fusion, a process vital for degrading cellular waste and maintaining homeostasis. Dysregulation of PLEKHF2 has been linked to pathologies, including cancer and neurodegenerative disorders, where disrupted membrane trafficking contributes to disease progression. For instance, mutations in PLEKHF2 are associated with impaired autophagosome-lysosome fusion, potentially exacerbating protein aggregation in conditions like Alzheimer’s disease.
Recombinant PLEKHF2 protein is engineered for research applications, typically produced in bacterial or mammalian expression systems to ensure proper post-translational modifications. It serves as a tool to study protein-protein interactions, lipid-binding specificity, and functional mechanisms in vitro or in cell-based assays. Researchers also utilize it to investigate PLEKHF2’s role in disease models, aiding drug discovery and mechanistic insights into membrane trafficking disorders.
Unlike other PLEKHF family members (e.g., PLEKHF1), PLEKHF2’s distinct domain architecture may confer unique cellular roles, making its recombinant form valuable for comparative functional studies. Ongoing research aims to clarify its regulatory networks and therapeutic potential.
