Fatty acid-binding protein (FABP) are carrier proteins for fatty acids and other lipophilic substances. They facilitate the transfer of fatty acids between extra- and intracellular membranes. FABS coordinate lipid trafficking and signaling in cells[1]. Various FABS differ in their tissue expression. IFABP is intestinal; HFABP is heart-type; BFABP is brain-type; LFABP is liver-type; AFABP is adipocyte; LMDABP is from flight muscle; TFABP is from testis.
RelevanceSome FABSs are linked to metabolic and inflammatory pathways.
