WB 1/1000 - 1/10000. Predicted molecular weight: 15 kDa.
  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • 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
