Fatty acid-binding protein 7 (FABP7), also known as brain-type FABP or B-FABP, is a small cytoplasmic protein belonging to the FABP family, which plays critical roles in lipid metabolism, intracellular transport, and signaling. Expressed predominantly in the brain, particularly in astrocytes, radial glial cells, and neural stem cells, FABP7 binds long-chain fatty acids, retinoic acid, and other hydrophobic ligands, facilitating their shuttling between cellular compartments. Its involvement in neurodevelopment, gliogenesis, and synaptic plasticity has drawn significant research interest, particularly in neurodegenerative diseases, brain tumors, and neuroinflammatory conditions.
Recombinant FABP7 protein is engineered using expression systems like *E. coli* or mammalian cells to produce high-purity, functional protein for experimental and therapeutic applications. The recombinant form retains ligand-binding capacity and structural stability, enabling studies on its interaction with fatty acids, membrane dynamics, and gene regulation pathways. Researchers employ it to investigate FABP7’s role in glioblastoma progression, where its overexpression correlates with tumor invasiveness and poor prognosis. Additionally, it serves as a tool to explore links between lipid dysregulation and Alzheimer’s disease, as FABP7 may influence amyloid-beta processing.
In drug discovery, recombinant FABP7 aids in screening inhibitors targeting its ligand-binding pocket, potentially modulating inflammatory or oncogenic pathways. Its application extends to biomarker studies, as FABP7 levels in cerebrospinal fluid or blood may reflect neurological damage. Recent advances in recombinant production (e.g., codon-optimized plasmids, affinity tags like His-tag for purification) have improved yield and functionality, supporting both basic research and translational efforts. However, challenges remain in mimicking post-translational modifications critical for its native activity, necessitating careful system selection. Overall, recombinant FABP7 remains a vital resource for unraveling lipid-mediated mechanisms in brain health and disease. (Word count: 398)
