Slc4a2 Gene Summary [Mouse]
Enables chloride:bicarbonate antiporter activity. Involved in several processes, including amelogenesis; negative regulation of CD8-positive, alpha-beta T cell activation; and positive regulation of enamel mineralization. Located in basolateral plasma membrane. Is expressed in brain; cornea; and testis. Human ortholog(s) of this gene implicated in osteopetrosis. Orthologous to human SLC4A2 (solute carrier family 4 member 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 Slc4a2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
