Fatty acid binding protein 4 (FABP4), also known as adipocyte FABP or aP2, is a protein involved in the transport and metabolism of fatty acids in cells. It is mainly expressed in adipocytes and macrophages, where it plays a crucial role in lipid trafficking and signaling pathways related to inflammation. FABP4 has been implicated in various metabolic disorders, including obesity, insulin resistance, and atherosclerosis. Research on FABP4 aims to further understand its molecular functions and potential as a therapeutic target for metabolic diseases.
