| 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 (By similarity). {ECO:0000250}. |

| Subcellular location: | |
Cytoplasm. |
| Tissue specificity: | |
Expressed in the small intestine. Expression in the mucosal cells of the ileum extends from the midvillar region to the villus tips. {ECO:0000269|PubMed:9139712}. |
| Induction: | |
By peptide YY. {ECO:0000269|PubMed:9139712}. |
| Domain: | |
Forms a beta-barrel structure that accommodates the hydrophobic ligand in its interior. |
| Similarity: | |
Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family. {ECO:0000305}. |
