Fabp4 Gene Summary [Mouse]
Enables hormone receptor binding activity; long-chain fatty acid binding activity; and long-chain fatty acid transmembrane transporter activity. Involved in long-chain fatty acid transport and positive regulation of cold-induced thermogenesis. Acts upstream of or within several processes, including brown fat cell differentiation; cellular response to lithium ion; and negative regulation of macromolecule metabolic process. Located in cytoplasm and nucleus. Is expressed in several structures, including adipose tissue; central nervous system; gut; heart; and integumental system. Orthologous to human FABP4 (fatty acid binding protein 4). [provided by Alliance of Genome Resources, Jul 2025]

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 mouse 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.
