Fatty acid-binding protein

The fatty-acid-binding proteins (FABPs) are a family of transport proteins for fatty acids and other lipophilic substances such as eicosanoids and retinoids.[1][2] These proteins are thought to facilitate the transfer of fatty acids between extra- and intracellular membranes.[3] Some family members are also believed to transport lipophilic molecules from outer cell membrane to certain intracellular receptors such as PPAR.[4] Levels of fatty-acid-binding protein have been shown to decline with ageing in the mouse brain, possibly contributing to age-associated decline in synaptic activity.[5]
