Recombinant Human FABP3 Protein

Fatty acid binding protein 3 (FABP3; also termed heart-type fatty acid binding protein) is a member of the intracellular lipid-binding protein family that may be essential in fatty acid transport; cell growth; cellular signaling and gene transcription. Previously FABP3 was involved in apoptosis-associated congenital cardiac malformations. FABP3 knockdown exhibited significant toxic effects on cardiac development and mitochondrial function; which may be responsible for the knockdown of FABP3-induced apoptosis. FABP3 as a candidate gene underlying the etiology of congenital heart defects. Overexpression of FABP3 inhibited cell growth and proliferation via negative regulation of the cell cycle and down-regulation of cell growth factors; but enhances cell survival in hypoxic or ischemic conditions. FABPs are known to be carrier proteins for transporting fatty acids and other lipophilic substances from the cytoplasm to the nucleus; where these lipids are released to a group of nuclear receptors such as peroxisome proliferator-activated receptors (PPARs).
