Sfxn1 Gene Summary [Mouse]
Enables L-serine transmembrane transporter activity. Involved in serine import into mitochondrion. Acts upstream of or within erythrocyte differentiation and iron ion transport. Located in mitochondrion. Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and integumental system. Orthologous to human SFXN1 (sideroflexin 1). [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 Sfxn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
