Slc9a1 Gene Summary [Mouse]
Enables sodium:proton antiporter activity. Acts upstream of or within several processes, including cardiac muscle cell differentiation; response to acidic pH; and sodium ion transport. Located in apical plasma membrane. Part of transporter complex. Is expressed in several structures, including alimentary system; early conceptus; gonad; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 19 and congestive heart failure. Orthologous to human SLC9A1 (solute carrier family 9 member A1).

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 Slc9a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
