General annotation (Comments)
| Function | 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. Ref.4 |
| Subcellular location | |
| Tissue specificity | Expressed in the small intestine. Highest expression levels in the proximal ileum. Ref.5 |
| Domain | Forms a beta-barrel structure that accommodates the hydrophobic ligand in its interior By similarity. |
| Sequence similarities | Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family. |
