Mouse Fatty acid-binding protein, intestinal,FABP2 ELI

FABP are thought to play a role in the intracellular transport of long-chain fatty acids and their acyl-CoA esters.

FABP2 is probably involved in triglyceride-rich lipoprotein synthesis.

Binds saturated long-chain fatty acids with a high affinity, but binds with a lower affinity to unsaturated long-chain fatty acids.

FABP2 may also help maintain energy homeostasis by functioning as a lipid sensor.
