Enables several functions, including long-chain fatty acid transporter activity; monocarboxylic acid binding activity; and phospholipid binding activity. Involved in several processes, including intestinal absorption; long-chain fatty acid transport; and positive regulation of fatty acid beta-oxidation. Located in several cellular components, including apical cortex; cytosol; and peroxisomal matrix. Part of protein-containing complex. Orthologous to human FABP1 (fatty acid binding protein 1).
