  • 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.
  • Tissue specificity

    Expressed in the small intestine and at much lower levels in the large intestine. Highest expression levels in the jejunum.
  • Sequence similarities

    Belongs to the calycin superfamily. Fatty-acid binding protein (FABP) family.
  • Domain

    Forms a beta-barrel structure that accommodates the hydrophobic ligand in its interior.
  • Cellular localization

  • ab60272 antibody (0.001µg/ml) staining of I-FABP in Human Duodenum lysate (35µg protein in RIPA buffer)
    Predicted band size: 15 kDa
    Observed band size: 16 kDa
    why is the actual band size different from the predicted?

    Primary incubation was 1 hour. Detected by chemiluminescence.
  • ab60272 staining I-FABP in Human small intestine by Immunohistochemistry (Formalin/ PFA-fixed paraffin-embedded tissue sections). The tissue sections underwent antigen retrieval by steam with citrate buffer pH 6.0. The AP staining procedure was used for detection.
