Mouse FABP2 ELISA Kit EZ-SetTM (DIY Antibody Pairs)

Fatty acid-binding protein 2 (FABP2), also known as Intestinal-type fatty acid-binding protein (I-FABP) is a protein that in humans is encoded by the FABP2 gene. The intracellular fatty acid-binding proteins (FABPs) belong to a multigene family with nearly twenty identified members. FABPs are divided into at least three distinct types, namely the hepatic-, intestinal- and cardiac-type. Using a human cDNA probe for in situ hybridization studies, they regionalized the assignment to 4q28-q31. The intestinal form of FABP was mapped to mouse chromosome 3 between the amylase and alcohol dehydrogenase-3 loci. Also, they may be responsible in the modulation of cell growth and proliferation.

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.
