Fabp4 Gene Summary [Rat]
Predicted to enable hormone receptor binding activity; long-chain fatty acid binding activity; and long-chain fatty acid transmembrane transporter activity. Involved in several processes, including fatty acid metabolic process; response to glucocorticoid; and response to gravity. Predicted to be located in cytoplasm. Predicted to be active in cytosol and nucleus. Biomarker of impotence and muscular atrophy. Orthologous to human FABP4 (fatty acid binding protein 4).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Fabp4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
