Fatty acid-binding protein

Jump to: navigation, search

The fatty-acid-binding proteins (FABPs) are a family of carrier proteins for fatty acids and other lipophilic substances such as eicosanoids and retinoids.[1] These proteins are thought to facilitate the transfer of fatty acids between extra- and intracellular membranes.[2] Some family members are also believed to transport lipophilic molecules from outer cell membrane to certain intracellular receptors such as PPAR.[3]
