Fatty acid-binding protein 7 (FABP7) is also known as Brain-type fatty acid-binding protein (B-FABP), Brain lipid-binding protein (BLBP), Fatty acid-binding protein, brain (FABPB), Mammary-derived growth inhibitor related (MRG). FABP7 / BLBP/ B-FABP belongs to the calycin superfamily and Fatty-acid binding protein (FABP) family. FABP7 is expressed in brain and other neural tissues. FABP7 / B-FABP could be involved in the transport of a so far unknown hydrophobic ligand with potential morphogenic activity during CNS development. It is required for the establishment of the radial glial fiber system in developing brain, a system that is necessary for the migration of immature neurons to establish cortical layers.
