Fatty acid-binding protein, intestinal (FABP2)

Links to databases


Fatty acid-binding protein, intestinal (also called Fatty acid-binding protein 2) is one of a family of >15 intracellular fatty acid-binding proteins that participate in the uptake, transport and intracellular metabolism of long-chain fatty acids. FAB2 is specifically expressed in the intestines, with highest levels seen in the jejunum of the small intestine, and generally much lower levels in the large intestine.
