Twenty years have elapsed since cytoplasmic proteins exhibiting high-affinity binding of long-chain fatty acids were first identified (Ockner et al., Science 177:56-58, 1972). These cellular fatty acid-binding proteins (FABPs) are now well established to comprise a ligand-defined group of macromolecules belonging to a family of cytoplasmic lipid binding proteins. Unique features of the FABPs are the existence of distinct types of FABP and that these are found in a variety of tissues in remarkable abundance, with some cells expressing more than one type. The physiological significance of the...
