Fads2 Gene Summary [Mouse]

Enables acyl-CoA 6-desaturase activity and stearoyl-CoA 9-desaturase activity. Involved in fatty acid derivative biosynthetic process and fatty acid metabolic process. Is active in endoplasmic reticulum membrane. Is expressed in several structures, including adrenal gland; genitourinary system; nervous system; and retina. Orthologous to human FADS2 (fatty acid desaturase 2). [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 Fads2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
