**Background of GP25L2 Recombinant Protein**
GP25L2 (Glycolipid Transfer Protein-like 2), also known as GLTPD2. is a member of the glycolipid transfer protein (GLTP) family, characterized by its ability to bind and transport glycolipids. This soluble protein is evolutionarily conserved and shares structural homology with GLTP, featuring a unique folding pattern termed the GLTP fold, which facilitates lipid recognition and transfer. GP25L2 is encoded in humans by the *GLTPD2* gene, located on chromosome 12. and is expressed in various tissues, including the brain, liver, and immune cells.
Functionally, GP25L2 is implicated in glycolipid metabolism and membrane dynamics. It selectively interacts with glycosphingolipids, such as ceramide and glucosylceramide, playing roles in lipid homeostasis, cell signaling, and membrane trafficking. Studies suggest its involvement in immune regulation, neurodevelopment, and apoptosis, though its precise mechanisms remain under investigation. Dysregulation of glycolipid metabolism is linked to pathologies like lysosomal storage disorders, neurodegenerative diseases, and cancer, highlighting GP25L2's potential relevance in these contexts.
The recombinant form of GP25L2 is typically produced using bacterial (e.g., *E. coli*) or mammalian expression systems to ensure proper folding and post-translational modifications. Purification methods often employ affinity tags (e.g., His-tag) for high yield and purity. Recombinant GP25L2 serves as a vital tool for *in vitro* studies, enabling researchers to dissect lipid-protein interactions, screen therapeutic compounds, and explore its structural biology via techniques like X-ray crystallography or NMR.
Current research focuses on elucidating GP25L2's role in disease pathways and its utility as a biomarker or therapeutic target, particularly in lipid-associated disorders. Its recombinant availability accelerates functional studies, bridging gaps in understanding glycolipid-mediated cellular processes.
