Technical Data
FABP4 (Fatty Acid-binding Protein, Adipocyte, Adipocyte-type Fatty Acid-binding Protein, A-FABP, AFABP, Fatty Acid-binding Protein 4, Adipocyte Lipid-binding Protein, ALBP)
Fatty acid binding proteins (FABPs) are small cytoplasmic proteins that are expressed in a highly tissue-specific manner and bind to fatty acids such as oleic and retinoic acid. Adipocyte fatty-acid-binding protein, aP2 (FABP4) is expressed in adipocytes and macrophages, and integrates inflammatory and metabolic responses. Studies in aP2-deficient mice have shown that this lipid chaperone has a significant role in several aspects of metabolic syndrome, including type 2 diabetes and atherosclerosis. It regulates allergic airway inflammation and may provide a link between fatty acid metabolism and asthma.
