Enables icosatetraenoic acid binding activity and long-chain fatty acid transporter activity. Involved in several processes, including long-chain fatty acid transport; response to fatty acid; and response to insulin. Located in cytosol and sarcoplasm. Human ortholog(s) of this gene implicated in hypertension and type 2 diabetes mellitus. Orthologous to human FABP3 (fatty acid binding protein 3). [provided by Alliance of Genome Resources, Apr 2022]
