Slc3a1 Gene Summary [Mouse]
Enables protein heterodimerization activity. Involved in carboxylic acid transport and gene expression. Located in brush border membrane. Is active in apical plasma membrane. Is expressed in several structures, including brain; genitourinary system; integumental system; intestine; and respiratory system. Used to study cystinuria. Human ortholog(s) of this gene implicated in cystinuria. Orthologous to human SLC3A1 (solute carrier family 3 member 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 Slc3a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
