FABP2, also known as the intestinal fatty acid binding protein (I-FABP), is expressed in the absorptive intestinal villous cells. It is mainly involved in intracellular transport and intestinal absorption of lipids. FABP2 has been considered a marker of mucosal injury and ischemia and serum I-FABP level is used as a tissue damage indicator. In addition, it is a marker of differentiated intestinal epithelial cells.
